Characteristics:
1. Process of the centerless grinding.

2. Cast iron hollow grinding roller features good wear resistance &l ong service life.

3. Either easily & quickly adjusting or processing adaptability.

Mine function:
These centerless grinding machines can process surface of needle roller, cylindrical roller, oil-needle, pin, and inner-outer ring of bearing etc. They can effectively improve the surface roundness and the geometrical precision of workpiece. Also the machines can widely reduce the work-piece surface roughness, featuring simple structure, high processing efficiency, & low cost etc.
