Mechanical polishing is a polishing method that removes the convex part of the surface of the workpiece by cutting or plastically deforming the surface of the material to obtain a smooth surface. Generally, oil stone strips, wool wheels, sandpaper, etc. are used, and manual operation is mainly used. A method o1.2 Chemical polishing
Chemical polishing is a process in which a material in a chemical medium causes a slightly convex portion of the surface to preferentially dissolve, thereby obtaining a smooth surface. The method can polish a workpiece with a complicated shape, and can polish many workpieces at the same time, and h1.3 Electrolytic polishing
The basic principle of electropolishing is the same as chemical polishing, which is to selectively dissolve the surface of the material to make the surface smooth. Compared with chemical polishing, it can eliminate the influence of the cathode reaction and has a good effect.See more on machinemfg polishing of mould steel
