Background

The polishing machine is classified into a mechanical polishing machine and an electrochemical polishing machine according to different operation modes. Mechanical polishing machines, also known as grinders, are often used for mechanical grinding, polishing, and waxing. The working principle is as follows: the motor drives the sponge or wool polishing disc arranged on the polishing machine to rotate at a high speed, and the polishing disc and the polishing agent act together and rub the surface to be polished, so that the aims of removing paint surface pollution, oxide layer and shallow mark can be achieved. The electrochemical polishing machine is a machine device for achieving brightness and smoothness of a metal surface through regular dissolution. In the electrochemical polishing process, a passive oxide film is continuously formed on the surface of the steel part, and the oxide film is continuously dissolved, and the former is stronger than the latter.
