Grinding is the finishing process of the parts. The surface roughness of the grinding can reach R_a0.2~0.012 (▽9～▽14). The surface quality is good, and the overall high precision can be obtained, including dimensional accuracy, geometric precision and partial positional accuracy. The roundness and cylindricity error can be less than 1μm, and the inch precision can reach 1-3μm. Grinding can process various metal materials such as steel, cast iron, aluminum, and hard alloy, and can also process non-metal products such as glass and ceramics. In the machinery industry, bushings and drills with high precision requirements are generally required.
