Whether you are here to learn about CNC milled parts or you are looking for a manufacturer that can service your milling project, you can find the answers to your questions by reading this article. Next, let's learn what milled parts are, what are their advantages, and more about CNC milled parts!
What are CNC Milled Parts?
CNC milled parts are customized machined parts made of metal, polymer, wood, or plastic, by a special computerized process known as CNC milling. CNC milling is one of the most important machining techniques used to manufacture various custom parts for different industries. It includes the use of highly mechanical gears and multi-point cutting tools to cut the material into different shapes.
The CNC milling parts are created by removing the unwanted parts of the material and turning it into a customized shape and design. The CNC milling parts produced at DEK use different axis for rotating tools whereas the workpiece stays in its place. DEK supports CNC milling for a wide range of materials. Using our advanced milling machines, we can create smaller-sized and custom-designed CNC milled parts for you.
What are the Advantages of CNC Milled Parts?
CNC milled parts include items that we use in our everyday life without even noticing, in fact, we depend on many of the milled products in our industries. They vary from simplest designs to customized and intricate models for prototypes and large production batches. DEK produces high-quality CNC milled parts that serve the following advantages:
- They are used to develop prototypes for the new product, you can test the prototype for quality and functionality before placing a large quantity order.
- CNC milled parts can easily be customized into any desired shape or design, and they can be made into perfectly finished products.
- CNC milled parts have their applications in every industry, including but not limited to; automotive, medical, food, mechanical, construction, aerospace, and kitchen utensils.
- These parts save money for business when ordered at a larger scale, and they make testing the prototype easier without wasting many assets.
What is the Difference Between 3-Axis, 4-Axis, and 5-Axis CNC Milling?
At DEK, we promise to develop precise CNC milled parts using our range of different axis milling machines. The most common CNC milling is done using 3-axis, 4-axis, and 5-axis machines, and the main difference between them is their movement. Here is a brief comparison of the three machining systems of CNC milling:
3-axis CNC Milling
This type of machine is used for performing the simplest kind of CNC milling operation, where the workpiece is kept stationary and the pointer works in the vertical direction. The 3-axis milling machines are suitable for the CNC milled parts in 2D geometry, due to the single fixture setup. The movement of the pointer is only possible in linear directions, such as x, y, and z axes. 3-axis milling is comparatively cheaper than other milling operations.
4-axis CNC Milling
Normally, the most commonly used CNC machine at any milling center like DEK is the 4-axis, because, unlike the 3-axis, it can rotate. The 4-axis spindle can not only move in x,y, z axes, it has an additional rotatory direction known as the A-axis. The workpiece in this type of machining is attached to the x-axis whereas the spindle can rotate and perform its milling in both horizontal and vertical manner.
5-axis CNC Milling
The 5-axis milling machines can perform the rotation in 2 more axes, which can either be B-axis and C-axis or A and C axes. The 5-axis milling can create the most elaborate and complex customized CNC milled parts with the finest finishing. DEK uses advanced 5-axis machines to produce complex 3D designs of milled parts for our clients, all over the globe.
What Materials can be Made into CNC Milled Parts
There is a wide range of materials that can be used to produce custom CNC milled parts, according to your requirement, budget, workability, and design. Here are some of the typical materials that DEK uses to manufacture CNC milled parts, are divided into two main types:
Metals
There is a large number of metals that can be used to develop CNC milled parts. Metals are used in milling when the milled parts need to be of high resistance, strength, and hardness. The following metals are frequently used in CNC milling:
Aluminum
Aluminum has all the properties that make a metal suitable for customized milling processes. Aluminum and its alloys have the greatest workability for any design of the CNC milled parts.
Brass
Brass is a soft metal alloy made from zinc and copper and serves a great purpose in the milling processes as it can be milled without lubrication. A great number of CNC milled products used in the auto industry are made from brass.
Titanium
Titanium holds such characteristics that make it easy to be welded and milled into customized shapes and designs. It is corrosion-resistant, lightweight, and tough in nature which makes it best for CNC milling.
Stainless Steel
Stainless steel has countless applications in almost every industry, thus a great material to be made into CNC milled parts. Different alloys of stainless steel are continuously being used in milling processes with their ability to be readily machined.
Plastics
Plastics are very lightweight yet they possess toughness and strength equal to some of the metal alloys, making them a renowned choice for milling materials. Several types of plastics can be used for making CNC milled parts, such as ABS, POM, Acrylic, Nylon, and HDPE, etc. Each kind of plastic used in milling has its own applications and benefits on a larger scale.
ABS
ABS (Acrylonitrile Butadiene Styrene) is a tough, impact-resistant thermoplastic polymer composed of acrylonitrile, butadiene, and styrene.
POM(Acetal/Derlin)
Delrin, also known as polyoxymethylene (POM), is a specific brand name of Acetal and is manufactured by DuPont. It offers high strength, high stiffness, excellent wear resistance, low friction, low water absorption, chemical resistance and high dimensional stability.
Acrylic(PMMA)
Acrylic, also known as PMMA, is a polymer material with excellent optical transparency, weatherability and chemical resistance. Acrylic is lightweight but strong, unbreakable and has excellent processing properties.
Nylon
Nylon has excellent thermal, mechanical, abrasion and chemical resistance, and is easy to machine, making it a versatile material for a wide range of CNC machining applications.
PTFE(Teflon)
Polytetrafluoroethylene (PTFE), commonly known as Teflon, is a high-performance synthetic polymer famous for its nonstick properties and versatility.
Are CNC Milled Parts Suitable for Small Batches or Large Quantities?
At DEK, we offer CNC milled parts for small batches as well as for large quantities, because we value your need and work according to your budget. However, CNC milling is best suited for large quantities as it creates a smooth workflow. For large quantities of the CNC milled parts, the components of each part are created in a separate step using specialized machines to create a large batch in the end.
This process saves time, creates parts with much more accuracy, and the speed of the production is increased. As opposed to the small-batch production of the CNC milled parts, the large quantities reduce the overall cost of the production, with minimum raw materials and faster end products. Despite all this, small-batch production has its own significance especially when your business needs unique designs for metal and plastic prototypes.
Which Surface Treatment is Used for CNC Milled Parts?
Most of the CNC milled parts require surface treatment after completing the milling operation. Surface treatment provides excellent finishing to the product’s surface. DEK uses different treatments and methods for the surface finishing of the CNC milled parts. Some of them include:
Anodizing
Anodizing is an electrochemical process that enhances metals' corrosion resistance, durability, and appearance, particularly aluminum.
Sandblasting
Sandblasting(Bead blasting) is one of the surface treatments used for the milled parts where the workpiece is sprayed with water coming out with really high pressure. The high-speed water contains some abrasive substance that covers the metal surface and gives it a better finishing.
Black Oxide
Get functional and aesthetic benefits in one with Black Oxide surface finishing. It's a matte black finish that also adds protection to metals, reducing corrosion and wear over time.
Electropolishing
Electropolishing enhances the corrosion resistance of metal by removing impurities and creating a clean, passive surface.
Powder Coating
This method of surface finishing is achieved by spraying some powdered coating onto the metal surface of the workpiece. Powder coating is done by the static electricity process, which sprays the powder evenly on the CNC milled parts. This method creates highly corrosion-free and strong final products.
