Abstract

A self-centering fixed bezel mandrel device of the type described, characterized by a non-rotating casing suitably attached to a lathe and supporting therein a generally cylindrical sleeve terminating at its forward end on a truncated inner surface. Conical an axially adjustable nozzle member inside the said sleeve, said nozzle member comprising a tubular body having at its front end a plurality of fingers spaced at equal angles and extending axially to grip a workpiece, combining the said fingers to each other to present an external frusto-conical contour adjacent the front end of the nozzle member, adjustable by axial backward movement of said nozzle, up to frictional contact with said inner frusto-conical surface of said sleeve for influencing the aforementioned fingers to the pinching contact with said piece to be processed, and means for axially moving said nozzle inside said sleeve to bring said conical-truncated surfaces to the mutual contact and outside it.
