Abstract : A turning apparatus, intended to be mounted on a work shaft for in-place cutting, may include a pair of mounting rings which are attachable to the shaft and which support a longitudinal annulate frame assembly which rotates about the area to be cut. A drive assembly is mounted on a mounting ring and engages a ring gear attached to the frame assembly for providing its rotational force. A longitudinal track assembly is mounted on and extends between the ends of the frame assembly. A carriage assembly is slidably mounted on the track assembly and is in operational engagement with a lead screw which is also mounted on the track assembly. The carriage assembly is adapted to hold a cutter for machining the shaft surface as the frame assembly rotates. A hydraulic indexing device incrementally rotates the lead screw in synchronism with the rotation of the frame assembly to move the carriage assembly and the cutter along the axis of the work piece.
