Problems solved by technology

However, this tempered glass also has the following problem: when the thickness of the glass is below 0.7t, the direction of the scribe line cannot be controlled due to crack-out during the scribing process of the cutter wheel, even when This problem also occurs when the glass with a thickness of 1.0t or more can be scribed by a knife wheel
However, the disadvantage of this laser-based cutting technology is that the process conditions are very complicated and the equipment is very expensive
Therefore, this technology is not suitable for low-cost and high-yield manufacturing processes

Abstract

A cutting method and cutting stage of toughened glass with which a piece of toughened glass is divided into unit pieces of toughened glass. The cutting method cuts a piece of toughened glass which is strengthened by forming a compressive stress in the surface of a raw glass plate. The method includes the steps of reducing the central tension inside a cutting portion of the piece of toughened glass that is to be cut by concavely bending the cutting portion; and cutting the piece of toughened glass by forming a median crack in the cutting portion.
