Abstract
To provide a method of processing a tempered glass in a simple and appropriate manner while a degree of freedom of processing is secured. Vibration of the processing device is controlled in a feedback fashion such that a vibration amplitude and a vibration frequency of the processing device approach to a target vibration amplitude and a target vibration frequency not to keep them in a range where a value of worsening the quality is generated. Further, a specified sample cycle of 0.3 msec or less in the feedback control is employed.
Claims3
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.
