A machining device for simultaneously machining a plurality of work pieces 71, 72 on one machining table 7 with high positional accuracy is provided. The machining device detects positions of the work pieces 71, 72 with detectors 91, 92 mounted to respective machining heads 81, 82. The machining device has respective units for, based on the positional data, moving the machining table 7 to a position where displacements of respective machining heads 81, 82 are nearly equal, and for moving machining ranges of machining heads 81, 82 so as to substantially eliminate displacements between respective machining heads 81, 82 and work pieces 71, 72. |
