ABSTRACT:
A turning head having a rotatably supported annular spindle with angularly arranged cutting tool elements, receives non-rotating elongated cylindrical workpieces which are successively fed through the turning head by a set of roller feed units. Each feed unit includes a pair of parallel spaced and simultaneously driven feed rollers which are supported for simultaneous lateral movement by corresponding arms pivotally supported on parallel spaced axes. The arms are simultaneously pivoted between predetermined selectable limits by a power operated actuating lever which engages both arms. The spindle is provided with a belt drive sheave disposed adjacent the tool elements and receives a removable non-rotating internal sleeve which supports an interchangeable bushing for precisely guiding the workpiece after being turned to a precise diameter. The sleeve also has passages for supplying a cooling fluid directly to the tool elements, and the turning head is supported between two of the roller feed units by a transversely extending guideway which enables the turning head to be quickly retracted for service.
