ABSTRACT:
An adaptor for automatic CNC turning lathes equipped with radial jaw chucks and opposing sub-spindles capable of gripping and moving a workpiece longitudinally during the cutting operation, the adaptor comprising a guide collet mounted coaxially on the longitudinal axis of the feed bore of the lathe, the adaptor being mounted so as not to interfere with the radial movement of the radial jaw chucks, where the guide collet allows for longitudinal movement of the workpiece during the machining operation but prevents the workpiece from deviating out of axial alignment during rotation, such that the cutting operation is performed adjacent the guide collet to prevent deflection of the workpiece by the cutting bit.
