Including Means Supporting Work And Additional Means Opposing Infeed Force Patents (Class 409/271)
  • Patent number: 8234771
    Abstract: The invention provides an enhanced method and system for machining an array of components. A holding mechanism is provided for holding an array of components in a machining process. The holding mechanism comprises: a rigid base plate and at least one support for holding a raw material while machining, one end of each support being coupled to the rigid base plate. The holding mechanism is further provided with a secure plate movably coupled to the rigid base plate. The secure plate is provided with one or more holding parts such as double-sided tape or guiding pins for holding the raw material. The secure plate can be elevated to hold the raw material during a machining operation such as peripheral machining.

  • Patent number: 5984600
    Abstract: The invention relates to a broaching machine comprised of a machine table for receiving a workpiece and being mounted in a machine frame. There is a platform which is driven so as to be displaceable relative to the table, as well as of one or more of axially operating broaching tools, which can be coupled with the platform. The machine table and the platform are displaceable in oppositely oriented directions. The machine table and platform are preferably driven via a common spindle drive. The spindles have two oppositely oriented threaded sections and the machine table and platform each are mounted on one of the two oppositely oriented threaded sections for a driving connection.

  • Patent number: 4531868
    Abstract: A high production surface broaching machine, in which a plurality of parts are located and clamped simultaneously in broaching position, broached, and simultaneously unclamped and discharged into an outchute. The plurality of parts are moved horizontally into position below the broaching position, and are then raised into accurately located broaching position against horizontal locating and ejection bar means. After broaching, the bar means pushes the broached parts down into laterally open recesses in an elongated bar, which is then moved longitudinally relative to a cam which guides the parts out of the recesses into an outchute.

  • Patent number: 4449872
    Abstract: A fully automatic machine tool for simultaneously broaching parallel slots on a plurality of workpieces mounted on a rotatable table in which the table is indexed between a plurality of broaching operations to revolve the workpieces and hence to effect rotation of the workpieces about their own axes with respect to the path of broaching tools.

  • Patent number: 4274775
    Abstract: A compound shuttle for a broaching machine having a pair of spaced parallel broach trains carried on a common slide reciprocable in forward and reverse passes past a work-piece mounted on a compound shuttle for positioning the work-piece into the path of a broach train during a forward pass, away from the broach train during reverse passes and moving the work-piece from axial alignment with one broach train into axial alignment with the other broach train upon completion of a forward pass.
