Title:
LASER PROCESSING MACHINE
Document Type and Number:
WIPO Patent Application WO/1992/005912
Kind Code:
A1
Abstract:
A laser processing machine to process a workpiece with laser beams outputted from a laser oscillator. Laser beams outputted from the laser oscillator (1) are projected onto a workpiece (23) through laser beam transmitting means (3, 4) and a condenser nozzle (5). Correspondingly to the movement of the condenser nozzle (5) along a fixed path (7), an angle between two cylinders (3, 4) of laser beam transmitting means changes. However, because of transmission of laser beams through said laser beam transmitting cylinders (3, 4), transmission distances of laser beams do not change. In other words, even when a position of the light condenser nozzle (5) changes, transmission distances of laser beams do not change. Accordingly, processing can uniformly be performed without fluctuating.
