Abstract:
Provided are a glass plate chamfering device, glass plate chamfering method, and glass plate production method with which chamfering quality in a glass plate can be improved without increasing the number of grindstones. A grindstone (10) formed in a cylindrical shape is divided in an axial direction into at least two divided grindstone portions, whereby the grinding performance of one divided grindstone portion (36) is configured to be higher than the grinding performance of the other divided grindstone portion (42). In other words, one grindstone (10) is endowed with a plurality of capabilities, and a divided grindstone portion (36, 42) selected in accordance with capabilities is used for chamfering a glass plate (16). For example, when carrying out a first chamfering process on an end surface (16A), grinding is carried out by pushing the divided grindstone portion (36) against the end surface (16A) of the glass plate (16). Then, when carrying out a second chamfering process, grinding is carried out by pushing the divided grindstone portion (42) against the end surface (16A).
