LASER MACHINING TOOL

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).
