That is, when the wobbling of the grindstone has occurred or the grindstone has reached the end of its life, there has been a problem that the end face shape of the glass substrate after the chamfering process becomes defective and the yield decreases. With the chamfering device of Patent Literature 1, it is impossible to detect the wobbling of the grindstone or the life of the grindstone.
