Abstract

A machine tool for processing workpieces, in particular metal sheets, has a punching device and a laser processing device. The punching device comprises a punch-side positioning device by means of which a punching tool component of a punching tool can be positioned in a definable position along an operating stroke axis of the punching device. The laser processing device has a laser processing unit and a laser accessory unit. The laser accessory unit can be positioned by means of an accessory unit positioning device with an activation movement in an operating position which can be defined by means of the punch-side positioning device. In the context of a method for processing workpieces, in particular metal sheets, which method is carried out using the above machine tool, the operating position of the laser accessory unit is defined by means of the punch-side positioning device.

Claims

15-1. The machine tool according to claim 1, wherein the punch-side positioning device and/or the processing unit positioning device a piston/cylinder unit.

16-1. The machine tool according to claim 1, wherein the laser accessory unit is a device for shielding a laser beam directed from the laser processing unit onto the workpiece and/or is a workpiece holding-down member.

17. A method for processing workpieces by a machine tool that has a punching device and a laser processing device, the method comprising:

positioning a punching tool component of a punching tool of the punching device by a punch-side positioning device of the punching device along an operating stroke axis of the punching device to a definable position, and

positioning a laser accessory unit of the laser processing device, which further comprises a laser processing unit, by an accessory unit positioning device of the laser processing device, with an activation movement to a definable operating position,

wherein the operating position of the laser accessory unit is defined by the punch-side positioning device.
