摘要： The present invention provides an NC machine tool which permits a check for the run-out of a spindle thereof at any time. The NC machine tool includes deflection detecting means (22) provided on a base within a machining area, and run-out diagnosing means (8) for conducting a diagnosis on the run-out of the spindle by calculating the amount of the run-out of the spindle on the basis of a deflection detected by the deflection detecting means (22) and comparing the calculated run-out amount with a predetermined tolerance. A test tool is attached to the spindle and rotated about an axis thereof, and the deflection of an outer circumferential surface of the test tool is detected by the deflection detecting means (22). On the basis of the deflection thus detected, the run-out diagnosing means (8) conducts a diagnosis on the run-out of the spindle. The diagnosis on the run-out of the spindle can be achieved through a simple and easy operation by moving the test tool into a detection area of the deflection detecting means (22).

摘要： 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.
