The polisher is mainly used to rub with other materials to make the surface smooth and even mirror-like. The motor drives the sponge, wool or grinding wheel installed on the polishing machine, and the polishing disk rotates at high speed. Because the polishing disk and the polishing material work together and rub against the surface to be polished, the purpose of removing surface pollution, oxide layer and shallow marks can be achieved. There are many types of polishing machines than grinding machines and grinding machines. The main categories are manual polishing machines and automatic polishing machines.

The type of manual polishing machine is relatively simple, mainly composed of a motor and a single shaft with a polishing wheel for polishing. Due to the more professional pursuit of efficiency, automatic polishing machines will have different machines for different products, resulting in many types of automatic polishing machines. For example: surface polishing of hardware products, flat products and articles, etc., can achieve the effect of mirror surface. It is a processing equipment that can achieve the brightest effect in processing.
