置制御装置。 In a machine tool whose spindle drive source is a speed-controlled electric motor, there is a rotational position detection disk connected to the spindle and rotates integrally with the spindle, and the rotation of this disk is immediately before the tool mounting/retrieval position on the spindle. a first sensor that obtains a detection output in a rotation range from The electric motor is rotated at a low speed until detection of , and the electric motor is rotated at a slow speed from the detection of the sensor to the detection of the second sensor, and the detected output states of the first and second sensors are determined from the tool removal position from the spindle. and a processing device that sets the tool mounting position to the main spindle at a state in which the tool mounting tool is fitted to the main spindle with slow rotation after detection by the second sensor. Control device.
