Pneumatic grinding machine
The utility model relates to a pneumatic grinding machine, the pneumatic grinding machine comprises a grinding head and ventifact pen, pen pen body and includes a windmill windmill installation department, take the pen body with the rotor, the rotor is arranged on the installation part. The grinding head includes a rotating body, a rotating shaft and a grinding layer. The rotating body is an elastic rotating body, one end of the rotating shaft is arranged in the rotating body, and the other end of the rotating shaft is arranged on the mounting part, and the polishing layer is covered on the outer wall of the rotary main body. Pneumatic grinding machine grinding surface such as mobile phone shell, because the rotating body is elastic, uneven surface grinding head can cater to the mobile phone shell in the grinding process, no grinding down when bumps, avoid grinding after extremely or step edge, improve the yield rate of the mobile phone shell, reduce scrap, and gas pneumatic grinding machine instead of manual polishing, which can improve the production efficiency, save labor cost.
