Computer numerical control machining, referred to as CNC machining, is a subtractive manufacturing process, it utilizes computerized controls to operate and manipulate machine and cutting tools to produce custom machined parts, by removing layers of material from the workpiece.
Precision CNC machining is with automated nature,it greatly increases reliability and repeatability, while reducing the potential for human error，meanwhile allows the CNC machining parts of high precision and high accuracy.
CNC machining process is appropriate for a large vary of materials, including metals, plastics, wood, foam, and composites, and finds application in a variety of industries, for example automotive, aerospace, construction and agriculture, it is able to produce a range of products, such as automobile frames, surgical equipment, airplane engines and garden tools, etc.

Surface finishes for CNC machined parts
CNC machining can produce parts with tight tolerances and fine detail from a variety of metal or plastic materials. Due to the subtractive nature of machining process, the surface of the part will have minor tool marks after machining. However,We can use a number of methods to improve the surface roughness, visual properties and wear resistance of the CNC machined parts. The most common metal CNC finishes listed below , which will help you to select the most suitable surface finish for your application.
The finish option with the quickest turnaround. parts have minor visible tool marks and potentially sharp edges and burrs, which can be removed upon request. The standard as -machined surface roughness (Ra) is 3.2 μm. Surface finish requirements can be increased to 1.6, 0.8 and 0.4 μm.
Bead blasting adds a uniform matte or satin surface finish on a machined part, removing the tool marks. Mainly for visual purposes.
Anodized (Type II Or Type III)
Type II adds a corrosion resistant, ceramic layer to the surface of the machined part. Can be dyed to different colors – clear, black, red, and gold are the most common. It is usually associated with aluminum and Titanium.
Type III adds a wear and corrosion resistant ceramic layer to the surface of the part. It is thicker and Offers greater protection than Type II. Available only for Aluminum and Titanium.

This is a process where powdered paint is sprayed onto a part which is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. Has a higher impact resistance compared to anodizing. Large range of colors available.Can be applied to any metal.
It is a process that uses an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode. The coating film will help to prevent corrosion and improve wear resistance, conductivity, reflection, and cosmetic appearance.
Advantages of CNC Machining
CNC machining is a manufacturing process which allows for increased efficiency through higher levels of automation and by allowing the machine and it’s computer controls to do all the work. As you can imagine, CNC machining provides a variety of advantages in custom machined CNC parts.
Automation: CNC machining remove the need of an operator for all but a few parts of the work.CNC machines can be left unattended for hours or even days if necessary, allowing operators to focus on other tasks.
Repeatability: Once a design has been fed into the computer, the CNC machine can repeat the manufacturing process multiple times. Also, you will always get a high level of precision in the component.
Range of Materials: CNC machining can be used to manufacture products from a variety of materials. These include bronze, steel, aluminum, as well as gold and silver. Polymers such as ABS, polycarbonate, and PTFE can be used with the machine as well.
Flexibility: A CNC machine can be completely reprogrammed in a matter of hours to produce a completely different product.
