PROBLEM TO BE SOLVED: To provide a laser beam machine capable of improving the machining speed. SOLUTION: In a laser beam machine in which the pulse-like laser beam from a laser beam oscillator is scanned by a galvano-scanner, and a printed circuit board 20 is irradiated with the laser beam, the printed circuit board hats an area to be machined on each side. Machining heads 15, 19 having the galvano-scanner are arranged on each side of the printed circuit board to perform simultaneous machining on each side of the printed circuit board. |
