Abstract
A grinding wheel for grinding a workpiece has an annular wheel base and a plurality of grinding stones arrayed in an annular pattern on a side of one surface of the wheel base. The grinding stones each have a base portion having a mounting surface where the base portion is mounted on the wheel base, and a wear-accelerated portion that has a grinding surface to be brought into contact with the workpiece and is more prone to wearing than the base portion.
