<p><P>PROBLEM TO BE SOLVED: To provide a torch changing device of large capacity in a flying optics-type laser beam machine. <P>SOLUTION: The table 15 of a laser beam machine is fixed, and a laser beam machining head 50 moves in the three-axial directions. A torch changing unit 300 is disposed on a set-up station 90 disposed outside a machining area at the end of the table. A torch storing device 100 stores a large number of torch holders 150 to be supported by forks outside a chain 130. A torch holder shifter 200 feeds the torch holder 150 at a shift position to the torch changing unit 300, and the torch of the machining head 50 is changed. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
