Abstract
PURPOSE: To enable a glass base plate having a concaved part to be formed very easily and at a high accuracy, by means of causing a polishing tool having the same curved surface as one part of the part of a concaved surface to be rotated at a high speed.
CONSTITUTION: A large sized glass base plate 9 is cut by a glass scriber or a diamond blade saw, thereby a glass base plate 1 is formed. Next, a corner surface 8 is cut by the surface grinding. The obtained glass base plate is set at a prescribed position of a jig 5, by means of arranging the direction of it, and is fixed via a pushing member, and a setscrew etc. Then, a glass base plate having a prescribed concaved part is obtained, by means of causing a grinding tool 4 having the same curved surface as one part of a concaved surface 2 to be rotated at a high speed by fixing the jig 5 on the work table of the slicing machine.
