Custom Finishes Guidelines For Precision CNC Machining Aluminum Parts
There are many surface treatments available for CNC machining of aluminum alloy parts,The most common being anodizing and sandblasting,For information on choosing anodized colors,Please refer to the RAL color chart and the Pantone color chart.
The initial surface of the part after CNC machine tool machining
This treatment can conceal minor scratches and imperfections on the surface after CNC machining, giving the parts a matte finish with a delicate, silky texture.
Anodizing not only covers CNC machining marks but also prevents surface oxidation, providing corrosion and wear resistance. It is also available in a variety of colors to meet different aesthetic requirements.
We use a polishing process to remove machining marks, making the surface of the parts smooth and refined.
Powder coating can be customized with different colors, matte/gloss finishes, and various other textures. This surface treatment offers high wear resistance and acid resistance, while also concealing minor imperfections on CNC-machined surfaces.
Sandblasting can better cover CNC tool marks, The surface is a matte finish, And it is available in a variety of colors. This surface treatment also enhanced corrosion and wear resistance.
