Abstract
A centering tool for rotary machine tools such as lathes and the like having axially aligned stocks comprising an end for engaging a workpiece in such a way that the engagement zone is substantially frusto-conical in configuration so that a workpiece having a centering recess disposed at an angle to the intended axis of the workpiece may be grasped so that machining can be accomplished about an axis in close proximity to the real axis so that a minimum of material is wasted.
Claims2
A centering mechanism for a rotary machine tool such as a lathe or the like, having a pair of opposed confronting stocks, a centering tool mounted in each of said stocks, at least one of said centering tools being symmetrically convex and substantially parabolically shaped to effect engagement with a recess in a work piece, said workpiece having a recess in each end thereof, in a substantially frusto-conical zone in such a way that the axis of the work piece is coincident with the axis of the stock even if the axis of the work piece recess bears an angular relation to the axis of the work piece.
