Roemheld FSS fixture solves clamping and support challenges of free-form surfaces

At the core of the design of the Roemheld FSS fixture is the use of Kostyrka UHF clamping and supporting elements. These can be used in any number to create the workpiece contact surface and can be positioned individually in a flexible configuration. The Roemheld Kostyrka UHF clamping and support elements consist of a guided and axially adjustable piston rod that can be clamped into any position by using a Kostyrka clamping sleeve. This procedure, and the clamping of the piston rods, are both fully automated. A vacuum pad with internal ball location that provides a defined contact surface is used as an interface to the workpiece. Depending on the workpiece surfaces and geometry, with the appropriate vacuum pads it is possible to obtain clamping forces (vacuum forces) of a minimum of 300 N for each UHF element.
