For CNC aluminum alloy parts, tumbling and black anodised surface treatment has the following multiple functions:
Functions of Tumbling:
1. Remove burrs and sharp edges: Make the edges and surfaces of aluminum alloy parts smoother, reducing the potential risk of scratches.
2. Improve surface roughness: Obtain a more uniform and fine surface, improving the appearance quality and touch.
3. Enhance dimensional accuracy: By removing a small amount of material, further improve the dimensional accuracy and consistency of the parts.
4. Increase fatigue strength: Reduce surface defects and stress concentration points, enhancing the durability of the parts when subjected to repeated forces.
Functions of black anodization:
1. Enhance corrosion resistance: Form an oxide film on the surface of the aluminum alloy to effectively block the erosion of external corrosive media.
2. Increase hardness: Improve the hardness of the surface and enhance the wear resistance.
3. Improve the appearance: Form a uniform black appearance with decorative properties to meet specific design requirements.
4. Improve electrical insulation: In some electronic equipment applications, it helps to improve the insulation performance.
The combination of these two surface treatment processes can significantly enhance the performance, appearance and service life of CNC aluminum alloy parts, making them better meet the requirements of various industries and application fields.
