A machine tool includes a time calculation unit calculating the time for a spindle to arrive at a target rotational speed, and the time for a spindle head to arrive at a target position; a comparison unit comparing the time to arrive at the target rotational speed and the time to arrive at the target position; and a drive control unit controlling the drive of the spindle and the drive of the spindle head. The drive control unit controls the drive of the spindle head, when a determination is made that the time to arrive at the target rotational speed is longer than the time to arrive at the target position, such that the time for the spindle head to arrive at the target position is longer than the calculated time to arrive at the target position, and less than or equal to the calculated time to arrive at the target rotational speed. Accordingly, the machine tool can drive the spindle head that is a control object in a power-saving mode.
A machine tool including a first control object and a second control object drives said first control object and said second control object, said machine tool comprising:
