<p><P>PROBLEM TO BE SOLVED: To provide a machine tool that prevents increase in cost with respect to increase in electric load mounted thereon. <P>SOLUTION: A control part 20 of this machining center continuously actuates first electric loads such as a fan 16, an interior light 17, and a back light 18. When second electric loads, such as a greasing pump 50, a door open/close motor 51, or a breakage detection motor 52 are actuated, the control part 20 calculates a total amount of operational power of the second electric loads to be actuated, and an operational power amount of the first electric loads in operation at the time, and then determines whether or not the total power amount exceeds a predetermined power amount. If the total power amount exceeds the predetermined power amount, the control part 20 selects the first electric loads which temporarily stop operation, actuates the second electric loads after the stop of the selected first electric loads, and restarts the first electric loads that has been stopped, after the operation of the second electric loads. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
