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 smooth surface; the working principle of a polishing machine is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed.
