This invention relates to a numerically controlled chamfering apparatus used to chamfer and grind the peripheral portions of a glass plate, such as a window glass for an automobile. An object of this invention is to chamfer a glass plate at a predetermined rate at all times in accordance with the variations in the grinding capacity of a chamfering wheel used for chamfering a corner portion of a glass plate. This invention is directed to a numerically controlled chamfering apparatus for glass plates, consisting of a mechanism for transferring a chamfering head (58) with chains (42), (62) on a horizontal plane in the direction of X-axis and the direction of Y-axis which crosses the direction of X-axis at right angles thereto, a swing mechanism composed of a rotary disc provided in the chamfering head, a pressure applying mechanism slidingly supporting the chamfering wheel in the direction of a normal to a periphery of the glass plate with respect to the disc, and adapted to move the chamfering wheel forward and backward, and a control unit for regulating the quantity of the forward and backward movements of the chamfering wheel. This apparatus is capable of chamfering a glass plate at a predetermined rate even when the shape of the glass plate and the diameter of the chamfering wheel vary. |
