CUTTING WHEEL FOR GLASS SUBSTRATE

摘要

PURPOSE: A wheel for cutting a glass substrate is provided to focus the generation and the growth of surface cracks to one side based on a cut line by asymmetrically forming a cutting blade. CONSTITUTION: A wheel(150) for cutting a glass substrate forms a cutting blade(155) along the outer circumference. Inclined planes(S1, S2) on both sides of the cutting blade are asymmetrically formed based on the edge of the cutting blade. The inclined planes are differently inclined with respect to a vertical line crossing the edge of the cutting blade. A first pressurizing area(P1) in which surface cracks are concentrated is selected as an ineffective area(NU), a second pressurizing area(P2) is selected as an effective area(U).
