Features of various types of centerless grinding wheels
Monolithic centerless grinding wheel
1. Single-piece grinding wheel, one-time pressing;
2. The width of the grinding wheel ring is relatively large;
3. The surface of the grinding wheel is seamless;
4. The outer diameter and thickness are not large.
Combined centerless grinding wheel
1. Multi-piece grinding wheel combination;
2. When the width of the grinding wheel ring is relatively small, it is conducive to uniform molding;
3. The multi-grain combined grinding wheel can be designed in sections in the axial direction;
4. It can be used as grinding wheel with large diameter and high thickness;
