ABSTRACT:
A tooling apparatus having a main somewhat hollow yoke-like housing adjustably positionable in micrometer increments relative to a supporting base member which may be readily and fixedly attached to the lathe bed. The yoke housing is provided with an enlarged opening for receiving a rotating assembly including a plurality of radially adjustable jaw members adapted for engaging the outer surface of an elongate work piece for retention of the work piece within the jaws thereof. The jaw members may be adjusted in micrometer increments for precise positioning of the work piece relative to the opening thereof, and relative to the lathe chuck, either centrally relative thereto, or offset therefrom. The housing and rotating jaw assembly are sealed and provided with bearings therein to permit rotation while enabling passage of fluid through hollow openings therein for enabling lubrication and cooling to permit high speeds of rotation 20 during machining of a work piece supported by the lathe chuck and the apparatus.
