CUTTER WHEEL FOR CUTTING GLASS

摘要

PROBLEM TO BE SOLVED: To provide a cutter wheel for cutting glass having high durability and a long life without adding an excessive load on the blade edge of the cutter wheel so that a continuous scribe line having the same width is formed by the cutter wheel when the scribe line is carved on a glass substrate and a vertical crack is deeply formed by encouraging the brittle fracture of the glass substrate by hitting point impacts onto the scribe line. SOLUTION: The cutter wheel for cutting glass has a V shape blade along an outer peripheral edge of a disk shape. The ridge line of the V shape blade is formed so as to be a continuous blade edge. Single or a plurality of projected parts by point hitting are formed at a side just under the blade edge. COPYRIGHT: (C)2010,JPO&INPIT
