Claims

[Scope of Claim for Utility Model Registration] 1. A cubic boron nitride grinding wheel segment having a base material with a cylindrical surface on the outer periphery, which has a mounting part on the center side to the grinding wheel shaft side, and is divided in the circumferential direction on the outer periphery of the base material. In a grinding wheel in which cubic boron nitride grinding wheel segments are arranged with a gap between them and the gap is filled with adhesive to fix the cubic boron nitride grinding wheel segment, the shape of the gap is viewed from the outside of the outer peripheral surface of the grinding wheel, and the shape of the gap is an axis that spans the entire width of the grinding wheel. A whetstone characterized by having a linear shape spanning the entire width of the whetstone other than a single straight line in the direction. 2. The grindstone according to claim 1, wherein the shape of the gap is a straight line in a direction different from the axial direction when viewed from the outside of the outer peripheral surface of the grindstone. 3. The grindstone according to claim 1, wherein the gap has a dogleg shape when viewed from the outside of the outer peripheral surface of the grindstone. 4. The grindstone according to claim 1, wherein the gap has a semicircular shape when viewed from the outside of the outer peripheral surface of the grindstone.
