<p><P>PROBLEM TO BE SOLVED: To provide a laser beam machine capable of effectively using a laser oscillator and machining various workpieces. <P>SOLUTION: A beam splitter 30 is freely positioned at an operating position where the beam splitter 30 interferes with a laser beam 2 and a standby position where the beam splitter does not interfere the laser beam 2. Also, a total reflection mirror 24 is freely positioned at a reflecting position where a laser beam 2q to be reflected becomes coaxial with a reflection beam 2b that is reflected by a total reflection mirror 34 and made incident to a total reflection mirror 25, and at a retreating position where the total reflection mirror 24 does not interfere with reflection beam 2b. When a laser beam is supplied to either one of machining heads 7a, 7b, the beam splitter 30 is positioned at the standby position while the total reflection mirror 24 is positioned at the reflecting position. When a laser beam is supplied to both machining heads 7a, 7b simultaneously, the beam splitter 30 is positioned at the operating position while the total reflection mirror 24 is positioned at the retreating position. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
