摘要

An automatic bar-loader for lathes including a channel (111) for feeding of a bar to the lathe mandrel and a bar-pusher (114) powered by an electric motor (115) controlled by a control unit (123) and having a head collet (116) for grasping the tail of a bar in the channel to make it run therein. The loader includes a sensor (120) for measurement of the axial shifting of the bar-pusher (114) designed for supplying a feedback signal to the control unit (123) for control of the bar-pusher motor.
