Title:
DEVICE FOR CHAMFERING GLASS SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2010/113982
Kind Code:
A1
Abstract:
A device for chamfering a glass substrate comprises: a table for supporting the glass substrate; a columnar whetstone used to form multiple annular grooves at predetermined intervals and in the axial direction in order to chamfer the face around the edge of the glass substrate supported on the table; a rotation drive part for rotating the whetstone; a first moving part for moving the whetstone orthogonal to the face of the glass substrate supported on the table; a second moving part for moving the whetstone in the direction of the face of the glass substrate supported on the table; groove shape detection means for detecting the groove shape, including position information in the orthogonal direction and in the direction of the face, for the multiple annular grooves of the whetstone; and a control unit for storing the standard groove shape of the design value of the whetstone, including position information in the orthogonal direction and in the direction of the face, at the position where the whetstone is attached in the standard position of the rotation drive part, and for controlling the first and/or second moving parts on the basis of the standard groove shape and the groove shape detected by the groove shape detection means.
