OBLIQUELY GROOVED GRINDING WHEEL AND METHOD FOR MANUFACTURING THE SAME

摘要

It becomes possible to provide easily and at a low cost a grinding wheel which is provided on a grinding surface thereof with oblique grooves formed without weakening the retention force of superabrasive grains on the grinding surface. In a manufacturing method for a grinding wheel in which a plurality of wheel chips each composed of an abrasive grain layer containing superabrasive grains and a foundation layer are adhered to a core attached to a wheel spindle carried by a wheel head of a grinding machine to be drivingly rotatable about a rotational axis and in which a grinding surface formed on the abrasive grain layers grinds a workpiece, drivingly rotatably supported by a workpiece support device of the grinding machine, in contact at a grinding point, the method comprises a wheel chip forming step of forming green wheel chips each having opposite ends in a wheel circumferential direction inclined relative to the wheel circumferential direction, a baking step of baking the green wheel chips to form baked wheel chips, and an adhering step of adhering the plurality of baked wheel chips to the core so that an oblique groove is formed between adjoining abrasive grain layers.
