を形成し、これら溝によつて同心円状に区画され
た各研削面をさらに周方向に分割してなる溝研削

合計がその円周の全長に占める割合を、砥粒層の
内周側から外周側に向かうほど小さくしたことを
特徴とする溝研削用砥石。[Claim for Utility Model Registration] A plurality of concentric grooves are formed in the abrasive grain layer provided on the base metal, and each grinding surface divided concentrically by these grooves is further divided in the circumferential direction. In the groove grinding wheel, the ratio of the sum of the circumferential lengths of the grinding surfaces arranged on the same circumference to the total length of the circumference is made smaller from the inner circumference side to the outer circumference side of the abrasive grain layer. A grindstone for groove grinding characterized by:
