摘要：
A chamfering apparatus is used to chamfer a peripheral edge of a glass substrate. The chamfering apparatus includes a grindstone having a cylindrical hollow end portion; a grindstone driving unit that rotates the grindstone around an axis of the cylindrical hollow end portion; a substrate rotation-driving unit that rotates the glass substrate around either one of an axis of the outer periphery and an axis of the center circular hole; and a pressing unit that presses the grindstone to the glass substrate such that an annular end surface of the grindstone contacts with an edge of either one of the outer periphery and the inner periphery of the glass substrate while the cylindrical hollow end portion of the grindstone faces with one of the outer periphery and the inner periphery of the glass substrate.
