Title:
HYBRID LASER PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2006/100798
Kind Code:
A1
Abstract:
A hybrid laser processing system (1) comprising a laser oscillator (4) oscillating laser light (L), and a high pressure pump (5) for supplying liquid wherein the liquid supplied from the high pressure pump (5) is injected from an injection nozzle (13) provided at the forward end of a processing head (6) and reaches a workpiece (2) as a liquid column (W). A first inclining face (13b) having a diameter reducing toward the workpiece (2) is formed on the injection nozzle (13) and a condensing lens (12) for condensing the laser light (L) locates the focal point of the laser light (L) on the workpiece (2) side ahead of the injection nozzle (13) so that the laser light (L) on the outside of the minimum diameter portion (13d) is reflected on the first inclining face (13b) and guided to the liquid column (W). Alignment of the condenser lens and the injection nozzle is facilitated, guided laser light does not spring out from the liquid column, and manufacturing cost and running cost can be reduced.
