ガラスの円板切り

抄録

Up to the present, glass has been cut by snap processing or grinding processing using a diamond wheel. Especially when a glass plate is cut into a circle, grinding processing is the main method. But the method requires a lot of time and energy, and, worse, makes a lot of noise. Thus a new method by means of local compression was used to cut the glass plate into a circle. This report refess to that method. The following's understood: 1) Only compression makes it possible to cut a glass plate into a circle. 2) Cutting by compression requires less energy and time. 3) Almost all parts of the cutting section achieve a mirror finish.
