Abstract
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 forms green wheel chips each having opposite ends in a wheel circumferential direction inclined relative to the wheel circumferential direction, bakes the green wheel chips to form baked wheel chips, and adheres the plurality of baked wheel chips to the core so that an oblique groove is formed between adjoining abrasive grain layers.
