The following are the most common metallographic abrasives: Silicon Carbide. SiC is a manufactured abrasive produced by a high temperature reaction between silica and carbon. It has a hexagonal-rhombohedral crystal structure and has a hardness of approximately 2500 HV. It is an ideal abrasive for cutting and grinding because of its hardness and ...

Summary. It is well known that abusive grinding may damage a workpiece, but the ways in which damage arises and the metallurgical factors influencing its occurrence are less widely appreciated. In fact, the surface of a workpiece is always altered metallurgi-cally to some extent by the passage of the grinding wheel.

Grinding force has an important impact on the ground precision and quality of a workpiece. At present, the effects of the workpiece structure and the change in the abrasive wheel diameter on grinding force are ignored during profile grinding. Therefore, to reduce the grinding force and improve the grinding integrity, profile grinding experiments were conducted on the …
