Surface Treatment Of CNC Machined Parts

Nov. 04, 2019

CNC machining produces parts with tight tolerances and fine parts from a variety of metal or plastic materials. Due to the reduction in the machining process, the surface of the part will have a small tool mark after machining. However, we can use a variety of methods to improve the surface roughness, visual performance and wear resistance of CNC machined parts. The most common metal CNC machining surface treatments listed below by CNC Precision Machining Parts Manufacturer can help you choose the surface treatment that best suits your application.

Knurled Round Thumb Screws

1, such as machining

Complete the option, the fastest turnaround time. Parts have small visible tool marks and possibly sharp edges and burrs that can be removed as required. The standard machined surface roughness (Ra) is 3.2 μm. Surface finish requirements can be increased to 1.6, 0.8 and 0.4 μm.

2, bead blasting

Bead blasting adds a uniform matte or satin finish to machined parts to remove tool marks. Mainly used for visual purposes.

3. Anodizing (Type II or Type III)

Type II A corrosion-resistant ceramic layer is added to the surface of CNC Machining Parts. Can be dyed in different colors - the most common are transparent, black, red and gold. 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 than the O type and provides better protection. Only for aluminum and titanium.

4, powder coating

This is the process of spraying a powder coating onto a part and then baking it in an oven. This results in a rugged, corrosion-resistant layer that is more durable than standard coating methods. It has higher impact resistance than anodizing. Available in a variety of colors. Can be applied to any metal.

5, plating

This is a process that uses current to reduce dissolved metal cations so that they form a thin coherent metal coating on the electrodes. The coating helps prevent corrosion and improves wear resistance, electrical conductivity, reflectivity and aesthetics.

6, custom finishing

CNC machining is a manufacturing process that increases efficiency by enabling a higher level of automation and allowing the machine and its computer to do all the work. It is conceivable that CNC machining has several advantages in custom machining CNC parts.

1. Automation: CNC machining eliminates the need for the operator to do everything except part of the job. The CNC machine can remain unattended for hours or even days, allowing the operator to focus on other tasks. .

2, repeatability: Once the design is sent to the computer, the CNC machine can repeat the manufacturing process multiple times. In addition, you will always get high precision in your components.

3, material range: CNC processing can be used to manufacture a variety of materials. These include bronze, steel, aluminum, and gold and silver. Polymers such as ABS, polycarbonate and Teflon can also be used with machines.

4. Flexibility: CNC machines can be completely reprogrammed in a matter of hours to produce completely different products.
