Bearing cylinderical wide-wheel centerless grinding machine for the outer surface of the bearing ring parts grinding .

Main Characteristics

About bearing cylinderical wide-wheel centerless grinding machine

1)   Wheel thickness wide grinding by the margin can be increased,  reduce the number of repeated grinding to improve productivity .  

2)    Machine tools for the layout of double-sided mobile bracket on the bed, the guide pulley only adjust the movement, the same workpiece position easily with a variety of feeders, easy automation.  

3)  The wheel rack with hydrostatic guide,   move sensitive  to achieve micro feed and has a certain vibration resistance, rail easy to wear.

4) The guide wheel speed control by AC frequency conversion stepless speed .
