GLASS CUTTING DEVICE, GLASS CUTTER, AND GLASS CUTTING METHOD

PROBLEM TO BE SOLVED: To prevent a phenomenon in which a crack is not uniformly formed by a wheel 10 of a glass cutter when a projection or an earlier-formed scribe line is present on glass.SOLUTION: When the wheel 10 is moved on the glass 300, a fracture layer 201 is formed causing a rib mark 202 t...

Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent a phenomenon in which a crack is not uniformly formed by a wheel 10 of a glass cutter when a projection or an earlier-formed scribe line is present on glass.SOLUTION: When the wheel 10 is moved on the glass 300, a fracture layer 201 is formed causing a rib mark 202 to be formed below the fracture layer and the crack 203 to be formed below the rib mark. To cut the glass 300, the crack 203 is required to be formed uniformly. Applying a force RRF to resist rotation for the rotating force RF of the wheel 10 makes it possible to form a uniform crack even when a projection is present on the glass 300. This improves glass cutting yield.
