ABSTRACT:
A tool spindle is rotatably driven by a drive motor with the spindle being mounted axially movable in a feed and retraction stroke. The drive motor also rotates a lead screw through a drive train with the lead screw moving the spindle in the feed stroke upon engagement of nuts therewith and permitting spring retraction of the spindle in the retraction stroke when the nuts are disengaged therefrom. A clutch in the drive train transmits a normal rotational force therethrough to the lead screw during a normal tool feed stroke, but disengages and interrupts normal rotational forces therethrough upon an abnormal resistance to the normal tool feed stroke reacting reversely through the lead screw to the clutch. Such abnormal resistance to the tool feed stroke could result from a selectively preset stop or an unforeseen obstruction or a tool dulled beyond proper use. Furthermore, upon disengagement, the clutch automatically actuates a valve disengaging the nuts from the lead screw and permitting spring retraction of the tool spindle in its retraction stroke.
