Abstract:
A laser machining apparatus comprising:a plurality of laser generators generating laser beams; a plurality of machining tools to focus laser beams; machining tool moving means for respectively moving said machining tools along predetermined paths; fiber-optic cables forming optical transmission paths to guide the laser beams outputted from said laser generators to the machining tools; laser beam confluence means intervened in the optical transmission paths for joining at least part of the laser beams outputted from the laser generators to be confluent into a fiber-optic cable or fiber-optic cables of a number smaller than that of the number of laser generators; and laser beam distribution means intervened in the optical paths for distributing the confluent laser beams to a plurality of laser beam outlets, the laser beams distributed to the laser beam outlets to be focused at the machining tools to perform machining.
