Aluminum Machined and Anodized Prototype
Project Overview:
CNC machining usually started from coarse milling with big cutting tools to fast remove unwanted material, to gradually fine milling by smaller tools.
For 3 axis CNC milling, workpiece was rotated manually and repositioned accurately to mill the part side by side, tolerance around ± 0.1 mm.
Customized fixture was usually applied to assist milling for high efficiency and tolerance. One deep hole was bored as it was out of milling capability.
The CNC machined prototype prior to surface finishing. All cutting lines and burrs on the surface were removed by sanding and beadblasting.
The final finishing of anodizing color. The anodized film provided aesthetic feeling as well as corrosion & abrasion resistance to the part.
Generally, 6061/6063 and 5052 were preferred series of aluminum material to get quality anodizing finishing of consistent color and texture.
