Abstract
An improved end-working attachment ( ) for a screw machine or a rotary transfer machine is particularly suited for use in rolling threads on a workpiece. The attachment broadly comprises: a slide base ( ) having an axis (y-y); at least two members ( ) mounted on the slide base for sliding movement in a radial direction toward and away from the slide base axis; a tool, such as a thread die ( ), on each member; an infeed mechanism ( ) for selectively causing the slide members to move toward the slide base axis such that said tools will engage said workpiece; and a return mechanism ( ) for urging the members to move away from the slide base axis.
