Abstract

Profile grinding of Hot Isostatically Pressed alumina and Silicon Nitride ceramics using Vitrified Crusliable diamond wheels in the creep feed mode is discussed. The influence of feed rate, cutting speed and diamond abrasive size on profile shape, surface finish and material removal rate were studied. The biaxial strength of the ground ceramic material was also measured.

Grinding wheels with the finest diamond abrasive particles produced the best surface finish (0.15 µm Ra).

When Silicon Nitride was ground at high material removal rates the coarsest diamond abrasive was found to give a lower biaxial bend strength (400 MPa) than that produced using the finest diamond abrasive wheel (960 MPa). In the case of alumina tile profile deviation at constant material removal rate was found to be lower using the finest diamond abrasive.
