The purpose of polishing

- Jul 26, 2019-

Polishing refers to the processing method of reducing the surface roughness of a workpiece by mechanical, chemical or electrochemical action to obtain a bright and smooth surface. It is a modification process of the surface of the workpiece by using polishing tools and abrasive particles or other polishing media.

Polishing does not improve the dimensional accuracy or geometric accuracy of the workpiece, but rather for the purpose of obtaining a smooth surface or specular gloss, and sometimes for eliminating gloss (extinction). A polishing wheel is usually used as a polishing tool. The polishing wheel is generally formed by stacking a plurality of layers of canvas, felt or leather, and the two sides are clamped by a metal circular plate, and the rim is coated with a polishing agent uniformly mixed with fine powder abrasive and grease.
