<p><P>PROBLEM TO BE SOLVED: To solve the problem of a conventional laser beam machining system that the weight of a machining head body is heavy and machining at high speed and high precision is difficult. <P>SOLUTION: The laser machining system includes an laser oscillator, a machining head body 3 to which a laser beam 7 is transmitted, a machining nozzle 2 in which an opening 8 is directed to a work 5, a gas supply system which supplies a machining gas 6 to the machining nozzle 2, and a partition plate 21 which is provided to the machining head body 3 so as to prevent the machining gas 6 from entering the inside of the machining head body 3. The machining head body 3 includes a machining lens 13 which converges the laser beam 7 to the work 5. The machining head body 3 includes a magnetic movement mechanism 4 which causes the machining lens 13 to perform biaxial linear movement in a plane vertical to an optical axis 1 of the laser beam 7 by magnetic driving with an electromagnet. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
