Claim Text:
1. A method of processing a chemical tempered glass having a surface reinforced layer by means of a processing device which is vibrated under rotation thereof, the method comprising the steps of: controlling vibration of the processing device in a feedback fashion such that a vibration amplitude and a vibration frequency of the processing device approach a target vibration amplitude and a target vibration frequency, together with setting the target vibration amplitude to be in a range from 3 μm to 9 μm and the target vibration frequency to be in a range from 60 kHz; and to 64 kHz; and employing a sample cycle of 0.3 msec or less in the feedback control.
