B 19405 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.
