[0002] Polishing machines, also known as grinders, are often used for mechanical grinding, polishing, and waxing. A motor drives a sponge or wool polishing disc mounted on the polisher to rotate at high speed. The disc and polishing compound work together to rub against the surface to be polished, removing paint contamination, oxide layers, and shallow scratches. The disc's speed is infinitely variable and can be adjusted as needed during application.

[0003] During the grinding and polishing process, different materials need to be selected for polishing according to the product. During polishing, different polishing heads are replaced according to the product conditions.
