Grindstone, grindstone manufacturing method, boring tool, abrasive grain positioning jig, and relief surface forming method

摘要

A grindstone is provided with a base (211) and a plurality of abrasive grains (210) aligned in a row and bonded on a surface (212) of the base (211). Each of the abrasive grains (210) has a relief surface (216) with a relief angle of a predetermined angle (β).

主权项

1. A method of manufacturing a grindstone in which an abrasive grain, having a truncated octahedron shape, is arranged on one surface of a base, the method comprising:
preparing the base, the abrasive grain, a temporary stand having a flat upper surface to which the abrasive grain is temporarily bonded, and an adhesive temporarily bonding the abrasive grain to the temporary stand; applying the adhesive to the upper surface of the temporary stand; temporarily bonding the abrasive grain to the upper surface of the temporary stand by the adhesive so that one of a plurality of surfaces of the abrasive grain adheres closely to the upper surface; inverting the temporary stand to direct the abrasive grain downward; facing the temporary stand to the base while the temporary stand is maintained at a predetermined angle; bonding the abrasive grain to the base by a plating layer; and detaching the temporary stand from the abrasive grain.
