The process of CNC machining of aluminum alloys is generally carried out by CNC machining centers (3 axes, 4 axes and 5 axes) / engraving machines on aluminum materials (6061, 6063, 7075 and other materials). Many products will require subsequent surface processing, such as sandblasting. Anodizing treatment / surface powder spraying / electrophoresis, etc.
