Title:
HYBRID LASER PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2007/013293
Kind Code:
A1
Abstract:
A hybrid laser processing system (1) comprises a laser oscillator (4) for oscillating laser light (L) to a processing head (6), and a liquid supplying means (5) for supplying a high pressure liquid to the processing head. In the hybrid laser processing system, a liquid column (W) is ejected from an ejection hole (48) provided at the distal end of the processing head and a workpiece (2) is cut by guiding laser light to the liquid column. The liquid column collides against the workpiece and bounces toward the processing head but since the liquid is blocked by a partition member (44), an air flow flowing toward the liquid column (W) in a gas passage between the processing head and the partition member is not disturbed and the liquid column can reach the workpiece without being diffused since an air flow is flowing along the liquid column. A long stabilized liquid column can be formed even if the ejection hole and the workpiece are located closely to each other.
