摘要

Apparatus for rotating and feeding elongated material removing tools comprises a pair of carriages which are reciprocable in opposite directions and each of which accommodates a rotary gripper movable into or away from engagement with the peripheral surface of the tool shank. When one of the grippers engages the tool and causes the tool to rotate and to move axially to advance its cutter into or along a workpiece, the gripper of the other carriage is disengaged from the tool and moves in opposite direction. Engagement and disengagement of grippers is controlled automatically and the grippers are rotated in their respective carriages.
