CNC Turning Anodized Aluminum

Turning is generally divided into rough car and fine car (including half fine car) two categories. The rough lathe strives to improve the turning efficiency by using large cutting depth and large feed without reducing the cutting speed, but the machining accuracy can only reach IT11, and the surface roughness is Rα 20-10 micron. Semi-finishing car and finishing car try to use high speed and small feed and cutting depth, machining accuracy up to IT10 ~ 7, surface roughness Rα10 ~ 0.16 micron. The precision can reach IT7 ~ 5 and the surface roughness is Rα0.04 ~ 0.01 micron. This turning is called "mirror turning". If the concave and convex shape of 0.1 ~ 0.2 micron is refined on the cutting edge of the diamond turning tool, the turning surface will produce very small concave and convex and neatly arranged stripes, which will present a damask luster under the action of light diffraction, and can be used as a decorative surface. This turning is called "rainbow turning".
