In order to investigate the characteristics of diamond wheel grinding of ceramic materials, grinding resistance, surface roughness of ground surface and image of grinding wheel were acquired wing experimental method. Through the experiments, this makes it possible to observe grinding wheel behavior by grinding resistance, surface roughness and cutting edge ratio. In case of Al₂O₃ cutting edge ratio is bigger than that of ZrO₂ and Si₃N₄. That's because Al₂O₃has a characteristic of low fracture toughness and bending stress.

In this study, experiments were carried out to investigate the characteristics of grinding and wear process of diamond wheel during grinding ceramic materials. Normal component of grinding resistance was decreasing while increased of spindle speed. The resistance of vitrified bond wheel was less than that of resinoid bond wheel because of imbedded large holes on the surface of cutting edge. Surface roughness was decreasing while of spindle speed. The surface roughness using vitrified bond wheel was less than that of resinoid bond wheel because of small elastic deformation. After continuous grinding of ceramics, cutting edge ratio of resinoid bond wheel decreased. For the case of vitrified bond wheel, cutting edge ration did not change.
