Claims

[Scope of Claim for Utility Model Registration] A generally disc-shaped top plate connected to a rotationally driven grinding wheel shaft, a peripheral wall protruding from the top plate toward the object to be ground, and the peripheral wall to be ground. A cup-shaped rotary grindstone comprising an abrasive grain section provided on an end surface on the object side, wherein the top plate section has a cooling device that communicates the inside and outside of the enclosure formed by the top plate section and the peripheral wall section. A liquid supply hole is provided, and a cooling liquid discharge part is provided on the cup-shaped rotary grindstone at a portion that approaches the processing surface of the workpiece to communicate between the inside and outside of the enclosure formed by the peripheral wall part. Features a cup-shaped rotating whetstone.
