[0002] Polishing machine, also known as grinder, is often used for mechanical grinding, polishing and waxing. Its working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer and shallow marks can be removed. The speed of the polishing disc is generally 1500-3000r / min, most of which are stepless speed change, and can be adjusted at any time according to needs during construction.
