ABSTRACT:
A machining device for simultaneously machining a plurality of work pieces71, 72on one machining table7with high positional accuracy is provided. The machining device detects positions of the work pieces71, 72with detectors91, 92mounted to respective machining heads81, 82. The machining device has respective units for, based on the positional data, moving the machining table7to a position where displacements of respective machining heads81, 82are nearly equal, and for moving machining ranges of machining heads81, 82so as to substantially eliminate displacements between respective machining heads81, 82and work pieces71, 72.
