This is a new-designed, high-efficient mobile polisher. It is mainly used to remove burrs, rusts and oxides from the surface of parts made by metal, nonmetal, plastics and chamfer and polish them at the same time. It has the features such as fine looks, reasonable construction, and easy operation, wide range of speed adjustment, high efficiency, and low noise. The workpieces overlap and polishing non-equality that happened in vibratory machine could be solved in this machine. It especially suits for small workpieces, workpieces with thick oxide layer and big burrs, special and complicated workpieces and thin walls that can not bear strong mechanical stress. It takes much less time than vibratory polisher to get the fine workpieces and the precision of workpieces can raise 1 to 2 grades. Its efficiency is ten times to the vibratory polisher and 20 times to the roll polisher.
