    Abstract: The apparatus of the present invention provides a broaching machine configured to produce an internal gear member. The broaching machine includes a broaching tool defining a central axis. The broaching tool includes a first set of broaching teeth configured to cut only a first flank portion of a plurality of gear teeth; and a second set of broaching teeth configured to cut only a second flank portion of the plurality of gear teeth. The plurality of gear teeth are formed such that the first and second flank portions of each gear tooth are tapered between a first end portion and a second end portion. The broaching machine also includes a motor configured to rotate the broaching tool about the central axis at a selectable rate and in a selectable direction. A corresponding method for producing an internal gear member is also provided.

    Abstract: In order to manufacture parts with an outer profile, a workpiece 32 is pressed by a pressure piece 24 through a ring-shaped cutting tool 34. The cutting tool 34 has a plurality of disks with inner cutting edges 62 for removing material from the workpiece 32. The cutting edges are progressively longer in the advance direction, so that each cutting edge removes material chips and the last cutting edge in the advance direction corresponds to the desired outer profile of the part. In order to improve chip removal, the chip chambers 74 located between the cutting edges communicate with the outside through radial connection openings 128 which are distributed all around their circumference. To hold the workpiece 32 securely on the pressure piece 24, a pressure pad 76 extends through the cutting tool 34 and is supported on the side of the workpiece 32 opposite to the pressure piece 32, and a hydraulic piston 80 generates a compression force on the pressure pad 76. To ensure a high dimensional accuracy, a calibrating tool with a passage whose dimensions at the rear outlet side correspond to the set dimensions of the part to be manufactured is arranged behind the cutting tool.

    Abstract: Work pieces, especially of rotational symmetry, are machined in a rotary broaching operation. The machine tool for this purpose has a tool carrier carrying a plurality of cutting edges arranged on a curved path in a radial work piece plane. In order to reduce down-time and to simplify the construction of the broaching apparatus, the insertion of a work piece blank into the apparatus and the removal of a finished work piece from the apparatus are preferably performed without interrupting the motions of a tool carrier. For this purpose the tool carrier is provided with a zone which is free of cutting tool edges. This tool free zone of the tool carrier is located downstream of the last cutting edge as viewed in the rotational direction of the tool carrier. This feature avoids the need for a return stroke of the tool carrier. Accordingly, respective return slides and return controls are also obviated. The apparatus is equipped with angular sensing devices for ascertaining the angular positions of the tool carrier at the beginning and at the end of a work cycle to provide respective control signals for the insertion and removal of a work piece in the zone without cutting edges and to start a new work cycle when a work piece blank is inserted into the machine tool.

    Abstract: A machine for broaching external gears comprising a frame, a pot broaching tool positioned with its axis vertical at the upper portion of the frame, a piston and cylinder device with its axis vertical located directly beneath the pot broach. The gear blank is positioned directly above a work support carried by the piston and is pushed upwardly through the pot broach to a position of clearance above. The cutting teeth of the broach are of course directed downwardly and each cutting tooth has a chip receiving space directly beneath it into which chips are formed during the broaching operation and from which chips are displaced for downward discharge.
