摘要： A rotary mechanism of a machine tool (driving device) includes a first motor for carrying out rotary driving and positioning of a workpiece support (rotary stacking-receiving die assembly), and second motors for supplementing rotation of the rotary stacking-receiving die assembly. The stop positioning accuracy of the rotary stacking-receiving die assembly due to the second motors is lower than the stop positioning accuracy of the rotary stacking-receiving die assembly due to the first motor.
