Abrégé

Provided is a method for processing toughened glass such that processing versatility is ensured and simple and accurate processing are enabled. Vibration by the processing tool is controlled by feedback control so that the vibration amplitude and frequency of the processing tool approach a target vibration amplitude and target frequency, and the target vibration amplitude and target frequency are set to values not within the range of quality deterioration occurrence values. In addition, a sample period of 0.3 msec or less is used as the sample period for the feedback control.

Provided is a tempered glass processing tool the estimated usable period of which can be increased as much as possible. A tempered glass processing tool (8) has a shaft shape and processes chemically tempered glass (1) having a surface strengthened layer while vibrating in the axis extension direction thereof while rotating about the axis thereof. The outer surface of at least a leading end portion is a diamond abrasive grain holding surface (8b-1) on which diamond abrasive grains are held, and in a leading end surface (8c), a recess (30) is formed in a central portion in the radial direction of the leading end surface (8c).

Abrégé

Provided is a strengthened glass processing method such that the production time per sheet of product glass can be minimized while ensuring the quality of the product glass. In a strengthened glass processing method for processing a laminated block (1a) as a chemically strengthened glass (1) with a processing tool (8) in a state in which the processing tool (8) is rotated and vibrated, prior to processing the laminated block (1a) with the processing tool (8), the laminated block (1a) is cut out of a laminated body (1A) as a chemically strengthened glass by using a dicing blade (84), and a finishing process is performed on an outer peripheral surface of the laminated block (1a) during the processing of the laminated block (1a) with the processing tool (8).
