Patent ID: 8916798

Claim:
Laser machining apparatus ( 10 ) comprising a holder ( 12 ) for holding a workpiece ( 11 ), a laser arrangement ( 16 ) for switching between a first operating mode (I) and a second operating mode (II), said laser arrangement comprising a first laser head ( 14 ) for use in the first operating mode (I) and a second laser head ( 15 ) for use in the second operating mode (II), the laser arrangement ( 16 ) for machining the workpiece ( 11 ) by thermal action in the first operating mode (I) wherein a thermally influenced zone (W) is produced on the workpiece ( 11 ) and for machining the workpiece ( 11 ) by laser ablation in the second operating mode (II) wherein at least partly or entirely the thermally influenced zone (W) on the workpiece ( 11 ) produced during the first operating mode (I) is removed, and the laser arrangement ( 16 ) comprising several infeed axes ( 13 ) for moving and/or positioning the holder ( 12 ) relative to the first and the second laser heads ( 14 , 15 ).
