置。 In a tool changer that performs tool exchange between a tool magazine device of an NC machine tool and a main spindle by rotating and inserting/extracting a tool change arm, the arm shaft has the tool change arm at its front end and is movable in the axial direction. A feed screw provided integrally, a nut member that can only rotate and is screwed into the feed screw, and the nut member is driven with the rotational direction of the feed screw in a brake state to insert and remove the tool exchange arm. The tool is characterized by comprising an NC-controlled first drive motor with a brake, and a second NC-controlled drive motor with a brake that rotates the tool changing arm while causing the nut member to be synchronously rotated by the first drive motor. NC controlled automatic tool changer.
