Claim:
1. 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.
