Main Applications and Structural Features

1. Model MM 1332 precise cylindrical grinder is used for grinding the rotary workpieces such as cylindrical or conical parts which have higher requirements of accuracy and roughness. Longitudinal travel is realized by hydraulic drive at stepless speed, or by handwheel. Rapid hydraulic advance and with drawal is effected in transverse, and the transversal feed is controlled by handwheel.

2. Wheelhead is supported by hydro-static-dynamic hybrid bearings, which have high accuracy and excellent rigidity.

3. Workhead has A. C. Freq-converted by dense-ball type bearing, which has excellent rigidity.

4. The machine is equipped with grinding indicating instrument, benefiting high-accuracy grinding.
