Threaded-Body Work Supports

Hydraulic work supports are used to provide a self-adjusting rest for workpieces and avoid their vibration and deflection under machining loads.
The threaded-body design allows for space-saving and direct installation into the fixture body. Hydraulic oil supply and venting are made via drilled 
channels. In case of the double-acting version the return stroke of the support plunger is effected in a precisely defined time, that is above all advantageous in cycle-dependent installations.

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. The support plunger is extended and retracted by means of a small double-acting cylinder. Contact to the workpiece is made by spring force. A pneumatic contact control is available as an option. The body with metallic wiper edge protects the subjacent FKM wiper against coarse and hot swarf.
