Title:
LASER BEAM RADIATING NOZZLE OF LASER BEAM MACHINE
Document Type and Number:
WIPO Patent Application WO/2003/011515
Kind Code:
A1
Abstract:
A laser beam radiating nozzle (1) of a laser beam machine suitable for machining (cutting and boring), by non−oxidation cutting, a relatively thick stainless steel plate with a thickness of approx. 8 mm or thicker, capable of suppressing the occurrence of plasma by allowing assist gas to be set to a low level while remarkably increasing a machining speed, and capable of effectively suppressing the occurrence of dross, characterized by comprising a cylindrical hollow part (9) with a diameter larger than the diameter of a nozzle hole (3) provided at the tip of the nozzle port (3), whereby an excellent machining with less contamination on cut faces can be realized.
