LASER BEAM MACHINING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a laser beam machining device compact in size and superior in a machining speed as well as machining quality. SOLUTION: First and second acousto-optic deflection elements 2a, 2b are arranged between a laser oscillator 1 and first and second galvano scanner system 3, 4. The movement of the laser beam 1a in a long stroke is performed by the first and second galvano scanner systems 3, 4 while a short stroke is moved by the first and second acousto-optic deflection elements 2a, 2b.
