CNC Milling–What You Need To Know

/in /by

When we talk about CNC machines, one of the types that we must attend to know everything about them are milling machines. Like the other machines that are manipulated by Computerized Numerical Control, CNC milling services machines are an update of conventional milling machines carried out by modernizing wave of recent times.

In basic terms, there is not much differentiation between CNC milling machines and conventional milling machines, so much so that there are special kits capable of converting a common milling machine into a CNC machine. Both formats have the same moving parts, such as the table, cutting head, spindle, and lateral and transverse displacement carriages.

However, CNC service machines do not have levers to operate these parts; instead, they have a screen inserted into a control panel, as well as a metal case to house the electronic and mechanical components of the device. These components include the CNC, which is primarily responsible for the movements of the milling machine.

CNC milling

CNC milling machine components

As we said before, a CNC mill shares some parts with its more basic and conventional counterparts. In the following list we will expose the components of a basic model of CNC  machine , highlighting those exclusive parts of them:

  1. -Column
  2. –Work piece
  3. -Strawberry
  4. -Milling table
  5. -Cutter head with spindle motor included
  6. -CNC control panel
  7. -Hoses for coolant liquid

On the other hand, CNC milling machines have two main axes for movement and two complementary axes for the cutting head.

Function of the Computerized Number Center

The main function of the CNC in a milling machine is to control the movements of the table, the transverse or lateral carriages and / or the spindle along the main axes by means of numerical data. Controlling the movements requires an almost perfect synchronization of all the components that allow the execution of the CNC process, such as the following:

  • Axes of displacement, main and complementary.
  • Transmission systems
  • Clamping systems for parts
  • Tool changers.

CAD and CAM programs

The use of CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing) programs is practically mandatory on all CNC milling machines. The intervention of each one facilitates the manufacturing process in an unequaled way. We will detail below the function of each one, also including the control software:

  • CAD: It is responsible for the design of the piece.
  • CAM: It takes care of the calculation of the displacements of the axes for the machining of the part, in addition to adding the speeds of the turns and the various cutting tools.
  • Control software: Each CNC milling includes its own. It receives the commands from the CAM program and executes the orders to move the moving parts of the milling machine according to these commands.

CNC milling services machines are adapted to milling profiles, cavities, surface contours and other operations. The milling table generally requires manual control of two or three axes of travel for the table in this type of work. However, depending on the complexity of the job and the type of machine, the process can be completely automatic.

Differences between a CNC milling machine and a conventional milling machine

An advancement of the CNC machining services over the conventional milling machine is the ability offered by the computer that controls them to carry out movements that cannot be performed manually, such as circles, diagonal lines and complex three-dimensional figures. It should be taken into account that a CNC machine allows the programming of the milling operations through numerical codes, to execute them by themselves without the need for an operator to handle them.

The computer of a machine controls the position and speed of the motors that drive the axes of the machine; as well as the movement of the table, the carriage and the spindle. An advantage that enables uniform production, through improved precision, as well as the quality of the final part.

Why Custom Machining Medical Parts?

/in /by

CNC medical componentsRecently, cutting tool concepts have been introduced that increase efficiency and optimize productivity in small part machining for the medical industry. As sliding head machines evolve for small CNC machined parts, so do cutting tools to deliver the performance required for maximum machine utilization. In UYEE industry, many tool areas have reached new levels of performance, of which rotary head threading and high-pressure coolant turning are two excellent examples.

The growth in the production of large volumes of long and thin screws in high performance metals, such as bone screws, evolves in parallel with the competitive pressure of their manufacture. This is the typical case for providers in the UYEE industry, where bone screws, for example, are machined in increasing volumes and for whom rotary head threading is an established method. The inherent stability of the process makes it the method of choice for high volume machining and demanding metals.

Choosing the Right Cutting Tools

The main benefit is a longer tool life, which means less Medical device prototyping machine downtime during the production process. In addition, the robustness of the cutting edge line can be optimized to achieve sharper and more reliable edges. Taking advantage of advances in other areas of machining, and developing specific index able cutters and inserts for rotating head threading of small CNC machined parts, offers great advantages in the manufacturing economy of CNC medical components.

The developments in inserts have provided the necessary means to achieve a new concept of cutting edges, which takes more advantage of the benefits of threading with rotary head. Coated carbide inserts, for example, offer longer and more predictable service lives, as well as the ability to achieve higher cutting speeds. This has resulted in higher productions and more CNC machined parts within required tolerance and finish levels. New insert grades, such as those with PVD / TiAlN coating, feature a genuine thin coating layer with excellent adhesion to the insert substrate. The grade has proven to be especially advantageous for the sharp cutting edges required for rotary head threading of materials such as those used in bone screws.

The Skills of Milling Medical Components

Operational safety and tool handling are additional essential features for higher performance in rotary head threading. The precision of the tool determines the quality of the insert seat, the rectification of the insert and the ease and reliability of the correct location of the insert at all times. Newly developed insert clamping for rotary head threading mills has improved cutting edge positioning accuracy, machining safety, and ease and time of tool change. Also, to ensure the high precision and surface finish required during the process, a smooth tangential cutting action is required.

Today, in rotary head threading, end mills should include precision ground specialty inserts and pre forms should be compatible with most types and brands of tailstock spindle. Despite already being a high-volume production process, meeting higher production and new CNC medical components demands requires new tool technology to achieve more advanced ring concepts in rotary head threading.

In one example of rotary head bone screw threading fabrication, with volumes of around half a million per year, in varied small batches, installing the modern index able insert tool resulted in machining savings that greatly increased manufacturing competitiveness . The long service life of the new tool allowed nine times as many components to be Medical device prototyping machined before having to change the cutting edge, when CNC medical components dimensions began to fall outside tolerance requirements. In addition to eliminating machine downtime, the easy maintenance of the cutter saved a lot of time in the tool room.

The Development of Coolant on Machines

Medical Device PrototypingThe coolant supply available in today’s sliding head machines offers new possibilities for optimized small CNC machined parts production. Replacing the conventional flow of coolant in the machining zone with a high pressure coolant system offers many machining advantages. In addition, the introduction of this assisted cutting means does not have to involve complicated and elaborate installations, since there are standard tools for this and the supply of internal coolant is already a very common practice.

In recent years, high pressure coolant machining has been continuously developed, resulting in today’s efficient concept. The great advantage of this system lies in the optimization of performance and chip evacuation when machining demanding materials, from the point of view of chip control, such as low carbon steels or super alloys.

The application of a tool concept to precisely direct the jets of high-pressure coolant to the cutting area is now also available for machining small CNC medical components. The current solution combines precisely directed coolant jets with a simple and safe clamping system.

This opens new doors for the efficient machining of demanding materials, especially in sliding medical device head machines, where groups of small tools are in very tight spaces and whose change and adjustment is slow and complicated. Both machining and tool change are optimized with the new tool holder system, equipped with location, locking system and connections for the coolant, on the machine.

 

Aluminum Handle Prototype

What Is The Most Commonly For Aluminum CNC Machining?

/in /by

Aluminum alloy is the most widely used non-ferrous metal material in the industry. It has low density, high strength, good plasticity, excellent electrical conductivity, thermal conductivity, and corrosion resistance. It can be manufactured for various products. It has been used widely in industry, such as our common electronic product housings, frames, and home windows. These are all aluminum alloy materials. According to different properties and application fields, it can be divided into ordinary aluminum alloy, high-strength aluminum alloy, and heat-resistant aluminum alloy. The most commonly used are 6061,5052，6063, 6082,7075 .The most commonly for aluminum CNC machining that there are main four points as below:

The Application Of Rapid Prototyping Industry

Due to the continuous update and change of technology in the rapid prototyping industry, CNC machining is already a very mature manufacturing technology, which is mainly suitable for processing complex curved surfaces, deeper inner cavity shells, multiple procedures, and high precision parts. Compared with traditional processing Way, obviously its production efficiency has been greatly improved, and in some respects it is no longer replaceable. When customers require CNC Aluminum Prototype and low volume production, its higher flexibility and superiority are presented. For example, making aluminum handle, because it is solid and heavier, and the surface requires fine sandblasting and black anodizing . 3D printing is also possible, but the surface will be rough and it will take a long time to polish, so the cost will be much higher. The CNC machined surface will be very smooth, as long as the burr is removed off. And if the customer needs to modify the design after received the prototype, it only needs to modify or adjust the programming accordingly in the subsequent production.

CNC Aluminum prototype machining

Applications In Automotive and Aerospace Fields

The traditional automobile industry usually pursues efficiency and scale. Now people have put forward higher requirements for automobile functions. This also requires automobile parts to meet higher accuracy. The application of CNC manufacturing technology can promote automobile processing enterprises to gradually become small-scale , Personalization and high-efficiency are developing rapidly to improve work quality and work efficiency.

In aerospace equipment, the most commonly used lightweight materials are titanium alloys and aluminum alloys. If the traditional methods are used to cut titanium alloys and aluminum alloys, it is easy to cause heat and deformation of the parts. In this way, the processing accuracy and the overall the quality will have a bad influence and the safety will be greatly reduced. However, through the use of CNC technology combined with professional high-speed machining technology, this problem can be solved well and the production safety and reliability are guaranteed. At the same time, the speed is faster and the quality is better to meet the needs of the equipment.

Aluminum Mold Making

Since aluminum alloy is a relatively soft metal compared to steel, it can be machined faster and cost less, usually saving 30% to 50% of cycle time. It is also much more convenient to repair the mold later. However, the life of aluminum mold is relatively shorter, which is why aluminum mold have not been widely used and promoted, and the application ratio in the injection molding industry is still not high.

Machinery Manufacturing

In work and life, we can see products and components which are made out of aluminum almost everywhere. These parts are basically produced through by molding, CNC machine, sheet metal, and profile extrusion, of which CNC machining occupies a certain proportion. With the development of society, people are more and more inclined to personalized customization. Due to market competition, new product designs are updated and the delivery time is shorter, which promotes the continuous development and higher demand of CNC technology.

CNC Machining Is Playing More and More Key Role in Rapid Prototyping Industry

/in /by

In the industry of the manufacture of various objects, we can see how new methods are emerging every day that have completely covered the needs of many customers, who before did not even dream of creating everything we have today. It is thanks to this evolution that we have the opportunity to standardize certain processes and techniques, but above all, that we can use the production line as an efficient enough way to achieve perfection in many of the creations and ideas that we need to materialize. This is how we have come to today, where there is a method that has definitely become one of the most important to start the creation of any part or object, it is practically mandatory to stop at this workstation to ensure that the development of the rest of the process is given properly; this is how the creation of the CNC Prototype and other types was born.

Machining in rapid prototype manufacturing

Creating a prototype is a task that all factories should take into account before starting to mass-produce objects, however, the technique that is used to start in this production line is also important. Machining has proven to be the most efficient way we currently have to achieve rapid and perfect prototypes and this technique intervenes in a very exact, economical and fast way. In whatever materials the technique is applied to, it will show that it is the best choice for prototypes.

CNC Prototype

Thanks to the existence of the CNC Prototype, we have been able to experience great changes in favor of the industry of the creation of objects and parts, and it is that this type of procedure allows the creation of rapid prototypes. This means that in the CNC Prototype manufacturing industry, there is the opportunity to use the material in a specific way, without wasting too much of it, and also immediately correcting certain errors that may occur at that moment.

CNC Aluminum Prototype

We can include in this list several materials that can be used for the manufacturing industry, an example of this variety can include some metals, such as aluminum. The CNC Aluminum Prototype is ideal for the handling and reservation of a rapid prototype, since, unlike other materials, it is easy to manipulate, and it also has all the advantages of the material due to aluminum material is the most commonly used metal in industry . Sometimes it is one of the preferred processes of those who want to be noticed in the market of a certain industry, and this material helps them a lot, since it is very easy to machine a prototype of these. Aluminum Machined Parts is one of the techniques most used in metals , and it is that it allows the creation of parts and objects that have exceeded certain levels of complexity. In this way, it presents a great advantage for the creation of rapid prototypes, since machining does not limit any of the people who require this service.

The Importance of Prototype During New Product Development

/in /by

Thanks to the birth of the prototype, we can create any object from a very simple idea. We can say that today we have a certain advantage over many aspects that we did not know in the past, and that is that it is inevitable to compare what we have now thanks to technology, to what we had before it. This applies to all aspects, that is, to all industries, so we can say that both evolution and innovation are capable of reaching every corner of the earth and every aspect of our lives. Its existence has positively marked the creation and development of ideas that range from the most everyday to the most complex. Thanks to this evolution, we can be sure that the way in which we perceive the world has improved remarkably, this brought as a consequence the simplicity in some processes, and the materialization of ideas that were believed unthinkable, especially in the world of the manufacturing.

The idea is the first step to build prototype.

Within all this great advance, a key figure has emerged that has been the driving force behind the manufacturing process in any area, managing to ensure the operation of any product, even if it has not yet been chosen to start a mass production process how the prototype took shape. Surely you have already heard about the rapid prototype, and although it is currently a known term, its importance is not sufficiently understood by everyone, and it is that we must speak openly about the importance of the prototype, so many could understand that since its creation , evolution has become present.

prototype model

This is how the Custom Rapid Prototypes figure was created

Many manufacturers understood this perfectly, and this is why they have dedicated themselves to adding areas intended for the creation of these figures, and, as we all know, the ideas for creating objects today are quite different from each other, making the standard disappear completely, giving way to the Custom Rapid Prototypes.

Importance of Prototypes and Custom Rapid Prototypes

As a fundamental part of the manufacturing process, it is important to recognize that the prototype has helped in many aspects to improve both the product and labor relations, which is why today we highlight its importance.

  • Improve solutions and teamwork

Usually, when working as a team, it is very important to take into account the various contributions that the team may have for the project, since in this way the most efficient solution can be determined to apply in the most unfavorable aspects of the work. Prototypes can show the most creative and innovative side of all those involved, since they can clearly see the limitations and shortcomings that the project may have, in real time.

  • Outperforms any sketch

Prototypes in ancient times were nothing more than sketches and drawings, which showed in a very theoretical way everything that could happen when the object was recreated, however, it was almost never possible to determine with certainty what would happen once these pieces or objects were in operation. By creating a prototype, you can study the object or part more deeply, without having to risk more elements in production, so it can be said that it is a safe way to have and test and sketch.

  • It is an excellent strategy to attract customers

We have seen how even the most famous inventors have shown in front of some investors a product, whose result and tests were ruined because they did not use a prototype to improve it. Creating a prototype for clients is a very good idea, since once they test the operation of the products, they can establish the faults that this may have, and they will be sure that this can be corrected effectively.

  • Usage tests are more realistic

Products should not reach their final phase to be able to do some use tests with them, where the reality regarding the user experience is determined, of course with the opportunities for improvements. This will allow the object to be fully optimized, this being based on errors at the end of the production line. The advantages of prototype manufacturing bring on all levels of production in industries are endless, and they allow all kinds of tests to be done on them, so it is important to have a valuable ally like UYEE.

 

 

PPSU CNC prototype machining

CNC Plastic Machining –Perfect Solution For Prototyping and Low Volume Production

/in /by

Plastics have come into our lives for many years now and have become such a part of our daily lives. However, plastics remain a really interesting technical solution which today exhibits amazing characteristics. These materials today cover a very wide range which therefore makes it possible to respond to many user issues, to the point that some suppliers are now developing specific plastics for each application requested in response to aesthetic and technical specifications. It has the added benefit of being formed in different ways; molding ,thermoforming, blowing, machining, etc.

Plastic machining, a relevant solution:

Usually, the plastic product is molded according to mass production forming processes ,thus making it possible to manufacture the same part in a repeatable manner at very low production costs. These processes make it possible to easily produce billions of parts. However, machining remains one of the processes for working the plastic to give it the desired shape. CNC plastic machining is easy and the diversity of plastics and sources makes it easy to find a technical solution to your expectations.The most important is that when you are looking for short run production ,in the meantime,the plastic part can not be made by 3D printing , machining will be very useful ,or we can say it is necessary.

Plastic machining helps to reduces costs:

Most of the time, CNC plastic machining is of interest in the production of prototyping and low volume manufacturing parts. It is favored over other processes because the machining has no fixed start-up costs, or very low compared to other forming processes. This therefore makes it possible to follow the development of a product, and to release different versions of the same product in a prototype and product development phase .

Machining can also make it possible to validate part geometry before launching production tooling with a view to controlling a schedule and a budget. Most of customers often use 3D printing or CNC prototype machining before launching and developing the production tooling to verify that the part meets their expectations in order to avoid or to limit as much as possible the subsequent retouching on the tooling leading to longer production times, additional costs and premature wear of the tooling .The diversity of sources and types of plastics makes it possible to ensure a supply in the right format (bar – plates – sheets – panels – etc.). Thanks to this multiplication of sources, it is possible to reduce CNC machined times and costs, to offer you an economical and inexpensive solution.

Take PPSU prototype machining as an example :

TYPICAL PROPERTIES OF PPSU

PPSU (Polysulfone) is an unfilled amorphous thermoplastic with excellent mechanical, thermal and electrical properties. PPSU distinguishes itself from PEI and PSU by a better impact resistance and chemical resistance. Also, the material exhibits superior hydrolysis resistance, in fact, it can be safely said that PPSU has virtually unlimited steam sterilizability, making it a very popular material for medical and pharmaceutical equipment that requires frequent steam sterilization.

Due to PPSU High softening temperature, relatively high cutting available Speed does not cause stickiness. The inherent toughness of these materials allows deep and smooth cuts without chipping or threshing. If cooling is required, the effect of spraying water is very good. . It is recommended to use a cutting speed of 150 m/min to 600 m/min and a feed rate of 0.05 mm/rev to 0.25 mm/rev. Milling can be completed at high speed without coolant or lubricant. The cutting tools used for aluminum machining work well. For example, a 13 mm wide and 2.5 mm deep groove can be end milled at a feed rate of 115 mm/min and a speed of 1,750 rpm.

PPSU CNC prototype machining

Above image of showing is CNC plastic prototype in PPSU material which we made for one of our customers in the past years. It applied for the kitchen device, when customer demanding a few pieces for test and checking the design CAD model during new product development phase. Obviously it’s impossible to be molded or 3D printed .Currently 3D printing can not work with PPSU material .It’s a type of not commonly used engineering material .and very expensive .So CNC machining is the only one choice .

Conclusion

Today,With the continuous innovation and globalization of 3D printing technology,it has been widely used in many sectors,from a small medical component to house building .However ,we can not still leave CNC plastic machining technology due to it’s quickness ,efficiency as well as almost no limitation on materials choice .

Does Prototype Equal to The End Product ?

/in /by

prototype model

 

Today ,When people are talking about rapid prototyping ,usually it’s involved in a question: is the prototype same as the end product ? especially on the function and performance of material .Most of designer or engineers have expressed concern about this question, in fact ,we should treat this question dialectically. That means it depends on what type of prototypes you discussed .Hereby ,as a prototyping manufacturer ,we are mainly discussing three pointing as below:

 

 

 3D Printing Prototype

As we all know. It is formed by resin or metal powder layer by layer for 3d printing prototype ,including SLA ,FDM ,etc .The principle of prototype manufacturing is the same. Obviously these procedures are totally different from the mass production in molding ,and also ,the materials of features and performance are a little bit different too .So we can say 3D printing prototype is not the same as the end product .However , in some industries,3D printing can not be replaced ,such as : in jewelry and medical sector ,due to the particularity of the industry, in most cases, customers demand to develop small and irregular shaped product with low volume manufacturing ,it’s a not good choice by molding or impossible , thus ,3D printing is a good option ,or it is necessary .In this situation, the prototype is just the final product .

Vacuum Casting In Soft Tooling

It’s a process of using RTV molding to cast plastic and rubber prototype parts .In this sector ,usually the material of prototypes are collectively called PU. There are some materials similar with ABS ,Nylon ,POM…etc .But they are not the real end product materials .The type of rapid prototyping process can produce low volume products quickly .RTV molding is silicone soft tooling ,it can save so much money and time to compare with steel molding .Is this type of prototype treated as the end product ? It had better check with the prototyping company where your product applied is ? what condition does the product work ? Usually for the housing shell of consumer electronics product with the short run requirements.It can be replacement totally.

CNC Prototype Machining

In most cases ,we can say this type of CNC prototyping is almost the same as the end product .Because no matter on prototype or final production phase ,both processes are not changed too much,they are all CNC manufacturing ,unless a bit difference on both efficiency and production cost ,such as: in the final production stage ,the vendor will add up more fixtures or  automation equipment ,or customers just request the finished of prototype as machined in order to save the cost ,but for later mass production ,they want a nice finished ,for example : anodized ,plated ,powder coated ..etc. However ,the manufacturing essence has not changed. There are two points as following worth discussion individually :

(1) CNC Metal Prototype :

For most metal products of industries ,the shape and structure is simple ,once the engineers confirmed the plan to create CNC prototype , then ,the final production will also be CNC machining way.We can say that the prototype equals to the end product due to both taking the same manufacturing process . Of course ,some of metal product is special and exclusive ,such as : the shell of automobile engine,in the beginning of product development test step ,building prototype in CNC , but for later mass production .Obviously it’s the best choice by molding due to the structure is quite complicated ,the production cost will be increase greatly in CNC machining , it dose not make any sense.

(2) CNC Plastic Prototype:

basically there are two cases custom plastic prototype ,one is for big prototype model in ABS or Polycarbonate ,ABS is the most commonly engineering  material ,and it’s the cheapest too .So when building a big model ,it can be split in a few small pieces and glue again after that in order to save the cost .It’s convenient to handle this process .Obviously it can not equivalent to the final product .Another one is for the stiff engineering material ,such as: Acetal/Delrin, PEEK. People must take CNC  because of 3D printing limitation for using material currently,if short run production for later requirements , It is still the best choice by CNC machining .At the moment ,plastic machining is playing more and more important role in rapid prototyping industry .

Conclusion

According to the analysis and statement above ,how to judge if the prototype equivalents to the final product ? It will depend on many factors : material ,application,manufacturing processes ..etc. If you are not sure ,then ,you had better check it with the manufacturer along with your design and details .They will answer you from a professional perspective。

 

CNC Titanium parts

Titanium Material Are Widely Applied in Defense and Aerospace Industry

/in /by

Today why are titanium machined parts more and more widely used in the industry ,this is because of the material special features . Titanium has several properties that make it an excellent metal for use in different industries: among them the aerospace and defense industries stand out. For this, titanium needs to be combined with a large number of metals, thereby forming much more stable and resistant structures.

Titanium when placed in union with steel, acquires surprising properties. The characteristics that stand out are resistance to corrosion, resistance to extreme temperatures, and finally a low weight. This makes it excellent for use in the manufacture of aircraft or vehicle parts that need little weight to prioritize over speed. Followed by that, there is one of the most common alloys on the market: the alloy with aluminum and iron. This alloy allows extreme hardness but at the same time maintaining a light weight and some flexibility. Being a flexible alloy, it is used for the direct manufacture of aircraft, and in some cases for prosthetics of all kinds.

Titanium in the aerospace area

The use of titanium is not very frequent in the commercial area because it is extremely expensive, which is why its main use is in the development of aerospace technology. For the manufacture of aircraft, the materials with the best properties are required, which must meet at least the following qualities:

  • Low friction and high resistance.
  • High temperature stability and thermal shock.
  • Dimensional stability over a wide range of temperatures.
  • Low gas emission under high vacuum conditions.
  • Electrical insulation from a wide range of temperatures and high voltages.

The component of titanium machining aerospace meets these properties so its use is capable of improving the safety and performance of aircraft engines and systems in extreme environments.

Titanium in the defense area

Just as many of the powers of titanium can be used for the manufacture of different aircraft, titanium also has the virtue of being used for the manufacture of defense devices and some vehicles. First of all, given the composition and structures formed through its alloys, it ends up creating materials that are resistant to friction, and that, despite having great hardness, is not hard to machine as long as taking the right manufacturing processes and cutting tools. This leads to the creation of critical components, such as helicopter landing gear, hydraulics and exhaust ducts. They are found on the propeller shafts of fighting boats because they are resistant to corrosion in salt water, and that is the same reason they are used for salt water aquariums, fishing lines, and even scuba diver knives. Special Forces. Some submarines are even made of this alloy.

Also, it is a material that is excellent in the manufacture of radar devices for combat troops that require fast movements and lightness in combat. Titanium radar devices are highly frequented by these groups since they have the necessary hardness not to lose quality, and at the same time they have an extreme lightness. Adding to the fact that several of these have different camouflage paints.

CNC Titanium parts

UYEE and the use of titanium

UYEE is a company that is aware of the properties and use of titanium in rapid prototyping industry. Therefore, he has begun to apply his knowledge to be able to use all the advantages of this metal not only for the creation of titanium components of defense devices, and for the creation of aircrafts, but also for the creation of prototype parts and pieces of machinery. That way, UYEE ended up creating a precision titanium machining specialized in the creation of these parts, not only to give quality to their machinery, but to make it as efficient and precise as those used in the defense and aerospace fields .Through the machining of this metal, it ends up creating pieces of true quality, impossible to break, and with all the faculties that a piece that would normally be used in other areas could have.

 

Aluminum Anodized

Why Custom Low Volume Aluminum Parts Through by CNC Machining?

/in /by

For the creation of any object, manufacturers have developed various possibilities so that the ideal shape can be chosen for the development of the project. Not in all the productions we can see that similar requirements are met for the creation of products, this is how the services that are given in a personalized way arise, to meet all the specifications of each of the clients. Being part of the manufacturing process of any product is not an easy task, since both manufacturers and customers must try to meet all the objectives in order to be accepted by their future customers and users, and these may have certain differences that must find a common ground. One of the aspects that many manufacturers must consider when recreating their clients’ projects is the quantity and quality of each of the objects that they will offer for them.

Why use aluminum machining ?

It is one of those techniques capable of achieving all the goals that are set in low volume manufacturing. For many, low-volume manufacturing seems very similar to other types of manufacturing, but the truth is that it is very difficult to achieve, because, being a very small production, you have to consider many economic aspects, and use the materials very intelligence and care. For this reason, there are not many processes that support low volume manufacturing, because balancing these aspects is a complicated task, however, to the relief of many customers, aluminum CNC machining service.

The  aluminum machining is a really effective way to treat this type of materials, since it is capable of creating a perfect piece, without wasting too much material, without molding cost, that is, it will use only what is necessary. The aluminum CNC service is undoubtedly a good strategy to be able to recreate low-volume manufacturing parts, since that interaction between the quantity and the quality of the object that is created is quite good.

The Application for Anodizing Aluminum Parts

As a prototype machining manufacturer, we often encounter that clients request their aluminum parts to be anodized .You’ve probably heard of the anodizing process if you work in the automobile sector or as an architect constructing tall buildings. However, anodizing is primarily utilized in the aerospace and electronics sectors, where specific parts must be ‘corrosion-proofed.’ There are several procedures to which various metals used in those sectors may be subjected. Because anodizing can be used for a wide range of metals, from aluminum to titanium, it is typically the best approach to preserve any particular aluminum surface. Aluminum is the most adaptable of them.

As a result, we’ll go through the essential components of anodizing aluminum pieces. We will discuss sealing anodized CNC machined aluminum parts, sharp dip anodizing, etching, voltage, and time, as well as going through and comparing the many types of anodizing procedures, such as hard coating.

Aluminum Anodized

Passivation Process

It is a chemical conversion process that enters the aluminum component and alters its stability. Anodizing creates an exterior barrier of aluminum oxide, which makes the material passive. This coating increases the object’s strength and durability while also protecting its attractiveness.

Anodizing’s Advantages

Electrical and thermal insulation is provided by the most widely utilized anodic oxidation coatings in industrial anodizing. Compared to applying paint to bare metals, the technique enhances the adherence of paint primers and glues. It’s also great for avoiding the galling of threaded components, which is a type of wear produced by adhesion between two moving surfaces.

Rectifiers, Chillers, and Process Equipment

If you’re wondering what type of equipment is required to complete the anodizing process, you might be surprised to learn that there are tiny anodizing kits designed for in-home usage. However, these “anodized aluminum at-home kits” are intended for relatively modest tasks, and they still need extensive knowledge to assure safe application. Several automated anodizing tanks for aluminum anodizing can be used in the apparatus.

Chillers

During the anodizing process, a significant amount of heat is generated. To effectively anodize a part, that heat must be removed, which implies that necessary procedures must be put in place to keep temperatures at an ideal level. Chillers are utilized to level out the metallic oxide deposition, and either water or air chillers aid in the chilling process. The temperature is regulated by using sensors to detect and valves to control it.

Voltage and timing

In two minutes, the technique is explained by Larry Chesterfield’s two-minute read on anodizing current density versus voltage. He provides a few mathematical calculations to assist you in calculating the appropriate voltage and duration to be utilized in proportion to the size of the object being anodized. It may anticipate the time required to produce the desired coating thickness if the current is fixed during the anodized cycle.

Makeup as a Solution

Anodizing aluminum is a labor-intensive process that requires the use of chemical baths and large equipment. Before commencing the procedure, determine the number of liters or gallons of solution required, considering the recommended acid-to-bath ratio (15 percent to 18 percent).

The Oxide Coating Structure

The anodic oxide structure is formed by the aluminum substrate and is fully composed of aluminum oxide. The aluminum atoms are progressively removed from the metal’s surface while the aluminum portion is submerged in the chemical bath, and a current is sent through it.

Pore Composition

The thickness of the aluminum oxide coating layer depends on the voltage applied to the bath and the amount of time the item is submerged in it. Higher voltage accelerates oxidation, and the time of the process influences the coating. Temperature and electrolyte properties, such as temperature and pressure, impact the dissolution rate of the metal surface.

Anodizing Varieties

One (Type II) is commonly referred to as’ regular ‘anodizing, while the other (Type III) is referred to as’ hard ‘anodizing. So, what happened to Type I, and are there any more processes that aren’t covered by the initial classification? We’re here to help you break things down equally and make them more understandable.

CNC aluminum parts

A cost-effective production process

During the low-volume machining process, keep in mind that the end product will be in your hands in no time, as the machines are very precise and fast when milling and turning. Aluminum machining simply takes care of “sculpting” the part until it is able to take the desired shape. The most convenient thing about this type of low-volume production through machining is that the delivery time is very fast, a lot of raw material is saved, and it is possible to work even with the piece that comes from a very complex design. For custom aluminum machining pieces there are no limitations, since the machines are really effective when creating parts, removing all products from any margin of error that may exist, creating parts that were previously believed impossible, and making the dream come true from any manufacturer, even if it is a very small project. If this is the process you need to start your business, go to an expert manufacturer, who can intelligently process your requests, and who is capable of giving you an excellent result, no matter how complex the creation of the parts.

Creation of parts from the service of CNC aluminum machining

Aluminum Heat Sink Parts

CNC Machining For Aluminum Heat Sink Manufacturing

/in /by

There are specific industries that require a helping hand to help them create components capable of fulfilling all their functions. In the electronics industry, it is important to gather all the necessary characteristics to create elements that are really useful, functional, and that can fit perfectly with a whole, that is, with many more elements, which together fulfill a function.

Aluminum MachiningIt is not easy to create quality pieces, it takes an expert in the field to achieve it, and also the knowledge and application of the correct technique. It is extremely important that each piece meets quality standards, and at least with the basic characteristics of itself, which will allow you to develop the multiple tasks that you will have. Well, we know then that in the manufacture of materials and parts used in electronics, it is very necessary to create very precise parts, which ensure the perfect operation of the entire system, which is why very exact and modern procedures are required.

Why Take Aluminum For Heat Sink ?

Metals are the best allies for the manufacture of certain pieces, and one of the most used is aluminum. There are some fundamental pieces that must be created from metals such as aluminum, since it has certain characteristics that absorb and distribute heat very efficiently, and likewise, can release it quickly to continue operating. These very important parts within an electronic circuit are often called heat sinks, and their role within a computer is really key to its operation.

Heat sinks are parts through which the temperature of a component can flow, so that it remains in operation, without heating, or at least that it remains at a temperature that is acceptable enough to continue its normal operation. Normally this piece distributes the heat throughout its surface area, preventing the rest of the components from collapsing. One of the techniques that has achieved excellent results in terms of the manufacture of components such as the heat sink, has been the aluminum CNC machining .

Why Get Heat Sink Made By CNC Machining ?

CNC Aluminum Heat SinkFor the most part, this group of components is manufactured through CNC Aluminum Machining, a technique that has been effective in creating so many other pieces of different metals and their alloys as well. There are so many benefits that aluminum machining is capable of bringing both manufacturers and their customers, however, there are a couple that are more decisive than others. The thermal conductivity of the heat sinks created from CNC machining aluminum is impressive, so they can easily be classified as the best on the market. The heat sinks that are built from the CNC aluminum prototype, usually achieve what could not be done with other previous techniques, and we know that the forms that these components come to acquire are really interesting. Otherwise, they would not be able to fulfill their main functions.

The manufacturers of these components have opted for aluminum CNC machining service to create them, and this allows them to devise new complex geometric shapes that can fulfill their heat sink functions in a more practical way. This is an opportunity that you will certainly not find anywhere, since it is difficult to accomplish a task like this, luckily machining has already come to our lives, to facilitate them, and to allow the creation of so many opportunities for the world. There are many industries that require machining services, so it is important that you can have complete control of the material.

Where Does Heat Sink Apply ?

aluminum Heat SinkOn many occasions, heat sinks are found in multiple places, as they are used in industries such as electricity, transportation, among others, so not all customers will want their components to have similar characteristics to each other. It is here where another of the properties of  aluminum prototype presents diversified solutions, and that is that they are capable of adapting to multiple environments, without risking the integrity of the component, combating humidity, corrosion and other damages.

The complexity to create a quality heat sink is really high, perhaps that is why it is not so common to find reliable manufacturers so that you can recreate these objects, however, there will always be UYEE, a company that is always able to overcome any challenge that is proposed to you, creator of the best quality components.

Assembly CNC Aluminum Prototype

Assembly CNC Aluminum Prototype Parts

/in /by

When we make an assembly with parts, each part ends up being an important piece in the total function of the machinery. If for some reason, one of the parts fails, it could end up having a massive failure, which would end up generating large losses for any company. For this reason, maximum precision in the elaboration of own assembly parts is of utmost importance, much more so if it is prototype parts: the part must be elaborated with the utmost precision and without margin of error.

Why use Aluminum?

CNC Aluminum Parts

In the Assembly CNC aluminum prototype parts creation industry there is a specific reason why the use of this metal is paramount. First of all, it should be noted that the most used material is its own aluminum alloys. The elements of these soft alloys tend to be extremely malleable and it is also added that they are recyclable. In this way a large amount of energy is conserved and subsequent damage to the environment is avoided.

In addition to this, aluminum has the property of joining other elements such as: magnesium, copper, zinc and silicon. By adding heat to the formula, they end up creating quite resistant alloys, which allow to have a great overload, without deforming. This fact is extremely important in the industry, since the slightest deformation can lead to massive damage to machines that can cost thousands of dollars. The fact of creating parts so resistant to pressure and rupture, allows the risk of damage to be minimal, if properly maintained.

And also,aluminum can be anodized with all kinds of colors ,when fitting some components up ,people not only want to test and check the function of the whole device , but also want to get the better visual experience and enjoyment，so with colorful components to fit up together , it will be easier to get this achivement . That’s why aluminum is quite welcomed and boomed in all kinds of industry.

Is the CNC viable for prototyping?

Most different industries are viewing 3D printing as a force that directly dominates the rapid prototyping market. But given this, CNC machining also becomes an important process when manufacturing aluminum prototype parts. This process allows us to understand the reason for the product, the forms that the prototype can take and finally allows the reasoning of the reason for being of these prototypes. CNC machined prototypes can perform many different functions with comparing to 3D printing way .

Machining could become an excellent manufacturing option when creating prototype parts, but for this we must take into account the different natures that a prototype can present. What will the device be used for? What material will it be made of? What material will be applied to the last part? If the user clearly investigates everything necessary, he ends up having much more acceptable prototypes.Sometime ,for some of rare metals ,machining is the only option to produce the relative parts .

UYEE as a solution for the inspection and verification of Aluminum Prototype

Watch Case Making By CNC Machining

/in /by

watch case machiningWe have some of customers are from Watch & Jewellery industry . They often place some orders for the watch case making ,from prototype to low volume manufacturing .We make them by CNC machining .For a watch ,the case is the main component of the whole body, it is designed and built to house the movement and all the components needed for the correct functioning of the watch. There are many different shapes of cases, from the simplest to the most complex with various materials .The most important for watch case making is that focus on detail and tolerance ,because it’s a type of small and high precision product .The use of equipment such as precision machine and special tools enable us to reduce production cost and obtain a case with high-level technical and aesthetic characteristics .Precision and attention to detail are our trademark.

There are three metal materials that we often use and recommend:

(1)Stainless Steel 316L Watch Case

Stainless Steel is one of the most used materials for the manufacturing of watch cases since it has always been recognized as an excellent metal given its excellent properties, however, there are different types, each with their own technical and specific characteristics. Here we often use 316 L as one of the best for making excellent watch cases. The “L” indicates that it has fewer parts of carbon (low carbon) inside and therefore has a greater resistance to wear.Sometimes, perhaps machining stainless steel 316L case may get difficult, however, we have the know-how to mill high-quality 316L case time and time again.

(2)Titanium Grade 5 Watch Case

watch case polishedTitanium is used in many sectors, it is recognized as a prestigious material due to its characteristics, it is in fact light, resistant in itself and corrosion. Therefore, even when we talk about owning a titanium watch we mean having a valuable product, with excellent technical characteristics and long-lasting .The disadvantage is that titanium machining turns out to be a harder work, in fact, dedicated tools are needed and some operations, which are good for other metals, must be completely rethought to adapt to the characteristics of titanium. We always prefer to use grade 5 because, even if it is more difficult to work as it is harder, but it allows for better polishing and has superior technical performances.In particular.it has a perfect finishing using PVD surface treatment .

(3) Bronze Watch Case

Bronze is a material that has been used a lot in the watch industry in recent years ,it is easy to work with but has the serious problem of oxidation, despite this it is used a lot because from a chromatic point of view, different and fascinating results are obtained .The problem of oxidation makes the management of the material more difficult, especially when you have finished pieces but not yet ready to be delivered to the customer, therefore greater care is needed than other metals and a deep knowledge of the material itself to know its reactions and features. Bronze must be protected and stored under certain conditions, it is always necessary to take into account the various factors that can alter the surface of the finished pieces, such as: humidity and high temperatures. Machining bronze case is a easy job ,because it’s not hard like Stainess Steel and Titanium metal .
