Description

Technical Field

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface. It is a modification process on the surface of a workpiece using polishing tools and abrasive particles or other polishing media; polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but is intended to obtain a smooth surface or mirror gloss, and is sometimes used to eliminate gloss.

[0003] In the prior art, when polishing metal parts, the metal parts are fixed on a workbench and polished with a polishing machine, or the operator holds the metal parts and moves them to the working end of the polishing machine for polishing.
