Abstract
To provide a method of processing a tempered glass in which a length of time required for manufacturing one plate of a product glass is significantly reduced while the quality of the product glass is secured. In the method of processing the tempered glass in which a stacked block (1a) acting as a chemical tempered glass (1) is processed by using a processing device (8) under a condition that the processing device (8) is rotated and vibrated, the stacked block (1a) is cut out from a stack (1A) acting as the chemical tempered glass (1) by using a dicing blade (84), prior to the processing of the stacked block (1a) by using the processing device (8), and a finishing to an outer periphery of the stacked block (1a) is also performed during the processing of the stacked block (1a) by using the processing device (8).

A method of processing a chemical tempered glass for processing a raw plate for a product of the chemical tempered glass having a surface reinforced layer by using a processing device which is rotated and vibrated, the method comprising:
- cutting out the raw plate for the product from a large substrate acting as the chemical tempered glass having the surface reinforced layer by using a dicing plate prior to the processing by the processing device to the raw plate for the product;
- and
- conducing a finish processing to an outer peripheral surface of the raw plate for the product, with the processing by the processing device to the raw plate for the product,
- wherein, while vibration by the processing device to the raw plates for the product as the tempered glass is feed-back-controlled such that an amplitude and a frequency of the processing device approach to a target amplitude and a target frequency of the processing device, respectively, values of the target amplitude and the target frequency are set to change at respective positions in a direction of thickness of the raw plate for product accompanied with the processing of the raw plate for product, which do not belong to a range of generating quality degradation;
- and
- the feedback control is carried out at every sample frequency of 0.3 msec or less.
