Claims

[Scope of utility model registration request]

(1) It is equipped with a plurality of through holes that penetrate through the thickness direction and open to the grinding surface, and is closely fixed to the plywood and driven to rotate, and the grinding fluid supplied through the center hole of the plywood is supplied through the through holes. In the thick-walled disk-shaped double-headed surface grinding wheel that is delivered to the grinding surface, the plurality of through-holes have substantially equal flow cross-sectional areas, and the center of the plurality of through-holes and the base plate. A relay passageway is formed between the plywood and the grinding wheel, and the flow cross-sectional area is smaller than the flow cross-sectional area of the through-hole, and a substantially uniform flow rate of grinding fluid is sent through the through-hole. A double-headed surface grinding wheel characterized by:

(2)' The relay passage includes a radial concave groove formed radially from the center of the grindstone on the contact surface of the grindstone to the base plate, and a radial groove formed in the circumferential direction of the grindstone. A double-headed surface grinding wheel according to item 1 of the patent application, which comprises a groove and an annular groove intersecting with the groove.
