Trueing manner and grinding process manner of grindstone

摘要

PPROBLEM TO BE SOLVED: To provide a method of truing a grindstone without causing grinding burn at a corner formed between an outer peripheral surface and an end surface of a workpiece, and a grinding method using the grindstone in grinding the outer peripheral surface of the workpiece with a narrower width than a width of a grinding surface of the grindstone by means of the grinding surface of the grindstone. PSOLUTION: The grindstone 25 has reduced contact pressure with the corner of the workpiece on a contact area of the grinding surface of the grindstone since a curvature is given to the contact area 25bb of the grinding surface 25ba with which the corner Wc formed between the outer peripheral surface Wa and the end surface Wb of the workpiece W comes into contact. Since heat flux of the corner of the workpiece can thus be reduced, the grinding burn of the corner can be prevented, thereby improving the quality of the workpiece. In addition, since the grinding burn of the corner of the workpiece can be prevented, grinding efficiency can be improved and a grinding cycle time can be shortened, thereby reducing a cost of grinding.
