Abstract: A laser machining tool is disclosed. The laser machining tool includes a machining device that has a movable carriage. A machining unit, which includes a machining head, is arranged on the movable carriage. The machining head is configured to direct a laser beam of laser light onto a workpiece to be machined. A flexible fibre cable for supplying the laser light from a laser light source is connected to the machining head. The machining unit can be moved linearly together with the machining head relative to the movable carriage. The flexible fibre cable is fixed to the machining unit with a first fixing means and fixed to the movable carriage with a second fixing means. The flexible fibre cable is freely movable for enabling a linear movement of the machining unit relative to the movable carriage in a predetermined guide plane between the first and second fixing means.

Abstract: The invention relates to a laser machining tool (100), in particular a laser cutting tool, comprising a machining device (1) which is guided on a bridge (10) and has a movable carriage (2), on which a machining unit (3) is arranged, which has a machining head (4), which is designed in such a way that it directs a laser beam of laser light onto a workpiece to be machined, wherein a flexible fibre cable (6) for supplying the laser light from a laser light source (16) is connected to the machining head (4) and the machining unit (3) can be moved linearly together with the machining head (4) relative to the movable carriage (2). The fibre cable (6) is fixed to the machining unit (3) with a first fixing means (7) and fixed to the movable carriage (2) with a second fixing means (8), wherein the fibre cable (6) is freely movable for enabling a linear movement of the machining unit (3) relative to the movable carriage (2) in a predetermined guide plane (G) between the first and second fixing means (7, 8).
