Abstract:
1. An end prep tool for machining the end of a work piece having an inside diameter, an outside surface and an end flange on at least one end of the work piece, said tool comprising: a) a mounting mandrel centering and internally mounting the tool to a theoretical center of the work piece, said mounting mandrel including a stem member having a first and second end, a longitudinal slot extending from the first end to proximate the second end, and a first annular member proximate the first end; b) a rotational head assembly having a central opening adapted to receive said stem member and opposing bracket members; c) a first tool slide assembly having a slide with a threaded feed screw journaled for rotation therein, the feed screw carrying a threaded feed nut, a tool block slidably mounted on the slide and engaged by the feed nut such that rotation of the feed screw displaces the tool block relative to the slide, and a pneumatic motor operatively coupled to the feed screw for rotating the feed screw; d) a rotatable housing having a first end and a second end, wherein the rotational head assembly is coupled to the rotatable housing proximate the first end; e) a gear ring having a first face operatively coupled to the second end of the rotatable housing; and f) a motor means driving the gear ring such that rotation of the gear ring rotates the rotatable housing.
