A polishing machine, also known as a grinding machine, is often used for mechanical grinding, polishing, and waxing.

Its working principle is that the electric 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 polishing agent, it rubs against the surface to be polished, thereby achieving the goal of removing paint pollution, oxidation layer, and shallow marks.

The speed of the polishing disc is generally between 1440-3000 r/min, and it can also be made into a continuously variable speed, which can be adjusted as needed during construction.
