    Description
    B 1.9405 Threaded-Body Work Supports

    Hydraulic work supports are used to provide a self-adjusting rest for the workpiece during the machining operations. They compensate the workpiece surface irregularities, also vibration and deflection under machining loads. The threaded-body design allows for space-saving and direct installation into the fixture body. Oil supply is made through drilled channels.

    In the body of the threaded-body work support a thin-walled locking bush is integrated, which locks cylindrically around the freely-movable support plunger when pressurising the element with hydraulic oil.

    There are three variations of plunger actuation:

    • Spring force
    • Air pressure
    • Oil pressure combined with spring force

    The elements are protected against penetration of swarf by a metallic wiper edge and sealed against liquids.
