摘要： A MACHINE TOOL ARANGEMENT HAVING A DEVICE FOR CONTROLLING THE CHUCK THEREOF, COMPRISING A BASE, A HEADSTOCK MOUNTED THEREON, AND A SLEEVE AXIALLY SLIDEABLE WITHIN THE HEADSTOCK, THE CHUCK BEING ROTATABLE WITHIN THE SLEEVE. THE CHUCK IS ARRANGED TO BE ROTATABLE BY A SHAFT DISPOSED PARALLEL AND NON-COAXIALLY THERETO BY A TRAIN OF GEAR WHEELS DISPLACEABLE TOGETHER WITH THE SLEEVE, RELATIVE TO THE SHAFT. THE SLEEVE IS ARRANGED TO BE SHIFTED AXIALLY BY MEANS OF A MECHANISM ARRANGED PARALLEL AND NON-COAXIALLY WITH THE SHAFT TO APPLY ROTATIONAL FORCE TO THE CHUCK IN A MANNER SUCH THAT THE TORSIONAL DEFORMATION THEREOF REMAINS CONSTANT THROUGHOUT THE ENTIRE CHUCK STROKE.
