PROBLEM TO BE SOLVED: To provide a constitution capable of simply and excellently conducting a maintenance such as a cleaning to cooling fins cooling a section in the vicinity of a laser-beam source. SOLUTION: A laser machining device 10 fits the laser-beam source in a main-body case 100, forms a constitution conducting a machining by irradiating an object to be machined with laser beams from the laser-beam source and has the cooling fins 140 mounted on the laser-beam source. The main-body case 100 has an opening section 105 penetrated to the inside and the outside of the main-body case 100 and a closing member 106 closing the opening section 105 in an openable and closeable manner. The cooling fins 140 are arranged at places facing the opening section 105 in the main-body case 100. COPYRIGHT: (C)2008,JPO&INPIT |
