Plunge grinding process of some fine ceramics is experimentally analyzed with metal bond diamond wheels, investigating wheel wear, grinding force, surface roughness, grinding ratio and so on. The wheel wear of diamond wheel becomes larger in the order of alumina, silicon carbide and silicon nitride, and wheel wear in alumina is as much as that in SCM 435 steel. Furthermore wheel wear increases with increasing setting depth of cut, speed ratio of work to wheel and grinding speed. Grinding force becomes higher in the order of silicon carbide, alumina and silicon nitride, and grinding force in silicon carbide is less than that in SCM 435 steel. Grinding force increases with increasing setting depth of cut and speed ratio and with de-creasing grinding speed. Surface roughness is mainly affected by grain size of diamond wheel, but not affected by work materials of fine ceramics or grinding conditions such as setting depth of cut, speed ratio and grinding speed. Grinding ratio which indicates grindability of work materials becomes higher in the order of silicon nitride, silicon car-bide and alumina of normal sintering ceramics, and that of reaction sintering silicon carbide be-comes lower.
