Claims

[Scope of Claim for Utility Model Registration] (1) A disc-shaped or cylindrical grinding wheel that grinds a workpiece by rotating a peripheral grinding surface on which a twisted groove is formed, which has a recess on at least one end surface. A grinding wheel characterized in that a grinding fluid supply hole is provided in communication between the concave portion and the twisted groove. (2) The grinding wheel according to claim 1, wherein the recess is an annular groove. (3) The grinding wheel according to claim 2 of the utility model registration claim, wherein the annular groove is a dovetail groove. (4) The grinding wheel according to claim 1, wherein the concave portion is formed in the shape of a short column. (5) The grinding wheel according to claim 1, wherein the grinding fluid supply hole communicates with the vicinity of the end of the outer peripheral grinding surface of the helical groove.
