METHODS OF SEPARATING STRENGTHENED GLASS SHEETS BY MECHANICAL SCRIBING |
摘要 |
A method of separating a strengthened glass sheet includes positioning a serrated scribing wheel at a position spaced apart from a first edge of the glass sheet and offset below a top surface of the glass sheet, where the glass sheet comprises a surface compression layer of layer depth DOL and a central region. The method also includes translating the serrated scribing wheel in a first direction at an initiation speed such that the serrated scribing wheel forms a crack initiation site comprising surface indentations extending into the surface compression layer, accelerating the serrated scribing wheel in the first direction from the initiation speed to a scoring speed to scribe a score line extending into the glass sheet to a median crack depth greater than DOL, and stopping the serrated scribing wheel in the first direction before the score line reaches a second edge of the glass sheet.
