B1911 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 deflection and vibration under machining loads. It is  recommended to use double-acting elements if applied in larger hydraulic clamping fixtures with long lines, especially if the return oil is cycled and has to return in a predetermined time.

This hydraulic work support contains a double-acting sliding cylinder. The support plunger is retracted in off-position. When pressurised at “A”, the piston pushes the support plunger against the inserted workpiece by means of spring force. As soon as the piston has touched the internal stop, the pressure
rises and the support plunger is hydraulically locked.
With type 1911 006, it is possible to effect locking separately through port "K".
For unclamping, port “A” is depressurised and port “E” is pressurised. The locking is released so that the hydraulic piston can pull back the support plunger to the off-position. The internal part of the work support is protected against dust and swarf by a sintered metal air filter.
