1.This is a new-designed, high-efficient mobile polisher equipped with world-famous converter to create stepless speed change and turn over automatically. It is mainly used to remove burrs, rusts and oxides of workpieces of metal, nonmetal, plastics, chamfer and polish them at the same time. It has fine looks, reasonable construction, easy operation, wide range of speed adjustment, high efficiency, low noise. The overlapping of workpieces and unevenly polishing happened in vibratory machine will be solved in this machine. It especially suits for workpieces of small sizes, of thick oxide layer and big burrs, of special and complicated shape even of thin walls that can not bear strong mechanical stress. It takes much less time than vibratory polisher to get the fine workpieces, the precision can raise 1 to 2 grades. Its efficiency is ten times to the vibratory polisher and 20 times to the roll polisher. 2. The machine is mainly used to remove the burrs and ruts oxide of suffice of pressing. Found. Heat treated workpieces that made of mental. Plastic. Chinaware. Especially for the complex and distorting easily workpieces.
