A brief introduction to the working procedure of the surface mirror of the workpiece on a plane poli
The surface polishing machine makes the surface of the workpiece mirror, not the last polishing process, but through the rough grinding, semi fine grinding, fine grinding and other processes. The lower the numerical requirement of the workpiece surface roughness is, the more the pre grinding process is before polishing, and the reduction of the surface roughness is gradual, the abrasive grain is coarse, the cutting ability is strong, the grinding efficiency is high, and the grinding surface quality is low. The plane polishing machine has fine abrasive grain, weak cutting ability and low grinding efficiency, and the surface quality of the grinding surface is high. Therefore, in order to improve the grinding efficiency, the size of the abrasive should be selected from coarse to fine, graded and lapping to the surface roughness required by the workpiece.
