Description
B 1.940 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 deflection and vibration under machining loads. Two sizes are available. The threaded-body design of the elements allows direct installation in clamping fixtures, in horizontal or vertical mounting position, and thereby a space-saving arrangement. Hydraulic oil is fed through drilled channels in the fixture body. Hydraulic locking is made together with hydraulic clamping of the workpiece, or independently.

Types of operation

For the support plunger there are 3 types of operation:

Off-position extended

The support plunger is pushed in by the workpiece against the spring force.

Off-position retracted

The support plunger extends pneumatically and returns by spring force.

Off-position retracted

The support plunger extends hydraulically with spring force and returns by spring force or hydraulically.
