Abstract
In this research, the reduction of the crack due to the grinding of ceramics was investigated by changing the modulus of elasticity of bonding materials of grinding wheels, and as the results, the following conclusion was obtained. (1) The occurrence of crack due to the grinding of ceramics was reduced as the modulus of elasticity E of the bonding materials of grinding wheels decreased. (2) The crack due to the grinding of ceramics reduced its depth of penetration with the decrease in the modulus of elasticity E of the bonding materials of grinding wheels. (3) The decrease in the modulus of elasticity E of bonding materials decreased the size of the cracks due to grinding, and lowered also the rate of crack growth. (4) As the rate of cooling of grinding fluid was larger, the occurrence of the crack due to grinding was promoted, and the cracks became larger.
