Grinding Operation - an overview | ScienceDirect Topics

The abrasive particles of the wheel with the softer grade would preferentially be pulled off rather than rupturing the surface and causing clogging of the grinding wheel. This is, in effect, a continuous process of self-dressing of the grinding wheel, thus ensuring that the surface of the grinding wheel always has sharp, fresh abrasive particles.
