Grinding wheel with abrasive segment chips including at least two abrasive segment chips whose circumferential lengths are different from each other

Abstract

A grinding wheel which is to be rotated about its axis for grinding a workpiece, including: (a) a base disk; and (b) a plurality of abrasive segment chips which are fixed to the base disk such that the abrasive segment chips are arranged on a circle having a center at an axis of the base disk, and which have respective circumferential lengths as measured in a circumferential direction of the base circle, wherein the plurality of abrasive segment chips includes at least two abrasive segment chips having the respective circumferential lengths which are different from each other, and wherein the abrasive segment chips are arranged with substantially no gap between each pair of the abrasive segment chips which are contiguous to each other in the circumferential direction.

Dependencies are inferred from the claim text.
