1. A laser machining tool comprising:
a machining device which is guided on a bridge and has a movable carriage, on which a machining unit is arranged, wherein the machining device includes a machining head, which is configured to direct a laser beam of laser light onto a workpiece to be machined, wherein a flexible fibre cable for supplying the laser light from a laser light source is connected to the machining head and the machining unit can be moved linearly together with the machining head relative to the movable carriage,
wherein 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,
wherein 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, and
wherein guide means defining the predetermined guide plane are provided in order to restrict movement of the flexible fibre cable in a direction running perpendicular to the predetermined guide plane, the guide means comprising at least two parallel stop elements for the flexible fibre cable.
