The key to the operation of the polisher is to try to achieve the maximum polishing rate in order to remove the damaged layer created during polishing as quickly as possible. At the same time, the polishing damage layer does not affect the finally observed tissue, i.e. false tissue is not caused. The former requires the use of a coarser abrasive to ensure a greater polishing rate to remove the abraded damaged layer, but the polished damaged layer is also deeper; the latter requires the use of the finest materials, which results in a shallow polishing damage layer, but a low polishing rate.
In industrial production, a polishing machine is a common device, and is mainly used for polishing the surface of an object, improving the surface roughness of the object and improving the surface performance of materials.
