Advanced ceramics have some excellent properities as the material for the mechanical components. It is, however, very difficult to grind ceramics with high efficiency because of their high strength, hardness and brittleness. In this paper, experiments are carried out to obtain the basic knowledge of ceramics grinding with high efficiency. Representative advanced ceramics, such as Al₂O₃, ZrO₂, SiC and Si₃N₄ are grond with diamond wheels. Special attention is paid to comparison between the conventional and creep feed grinding of ceramics. Results obtained in this study provide some useful informations to attain the high efficiency grinding of advanced ceramics.
