METHOD AND DEVICE FOR SEPARATING A FLAT WORKPIECE INTO A PLURALITY OF SECTIONS |
摘要 |
The invention relates to a method and to a device for separating a flat workpiece (1) into a plurality of sections (7) using the technique of thermal laser beam separation (TLS). In the method, prior to the TLS step, at least one line (2) of modified material is generated along one or more predefined separating lines in the workpiece (1) by way of local material processing using a further laser, which results in a reduction of the breaking stress of the workpiece (1) along the separating lines. Said line (2) is thereby entirely, or at least sectionally, generated at a distance from the surface of the workpiece (1). By means of the method, a higher quality of the edges of the separated sections is achieved. |
