PURPOSE:To uniformize the load of a grindstone at working time and to perform a uniform work without unevenness, by performing the grinding of a work after forming the outer peripheral and inner peripheral angular parts of a grindstone on a slight inclined face by dressing. CONSTITUTION:The outer peripheral angular part 2 and inner peripheral angular part 3 of a grindstone 1 are formed on slightly inclined faces 2a, 3a by dressing. The corners of the outer peripheral angular part and inner peripheral angular part which are at acute angles become to be removed and the angular part of the grindstone 1 consisting of the lower end face 1a and inclined faces 2a, 3a of the grindstone 1 is formed. This angular part makes an obtuse angle by the inclined faces 2a, 3a and the grinding of a work W is performed by the angular part making this obtuse angle. |
