Two methods are proposed to prevent chipping of the work corners in grinding of ceramics : one is to press a splint to the work end with a loading system (splint press type), the other to fix it to the work end with adhesive (splint adhesion type). The applicability of these methods are experimentally investigated in single point grinding and theoretically confirmed by estimating the deformation constraint of the work, i.e., the resistance to the penetration of the swelled work into the splint. It is found that the size of chipping becomes small under appropriate conditions : it is recommended to use soft splint such as aluminum under sufficient compression in the splint press type, and to adopt thin adhesive with high Young's modulus in the splint adhesion type.
