ABSTRACT:
The tool is especially adapted for field use for spiral machining annular and solid work members of any geometric configuration, including but not limited to pipes, valves, flanges, etc., and comprises a stand carrying a hollow main shaft which rotatably supports a face plate which, in use, is positioned opposite to the work member. A tool holder is mounted for radial travel on the face plate. A motor rotates the face plate. The rotary motion of the face plate causes the tool holder to rotate and linearly travel. Preferably, the tool holder is mounted on a frame disposed for adjustable pivotal movement relative to the face plate.
