Vacuum clamping of freeform components on show at AMB 2026

On stand B30 in hall 1 at AMB 2026 (Stuttgart, 15-19 September), the Roemheld group will demonstrate its versatile clamping system, FSS, for rapidly securing free-form components prior to machining. FSS reduces set-up times and maximises machining centre utilisation in high-mix, low-volume manufacturing environments, which are becoming increasingly prevalent.

The new work-holding solution, which includes its own PC/PLC control box, adapts quickly to a new profile shape, without requiring time-consuming fixture changes. The system allows the quick, reliable and firm holding of virtually any workpiece without deformation or inducing clamping stresses. In particular, lightweight and thin-wall components made of plastic or aluminium up to 15 m in length can be clamped precisely and without the need for a nesting mould or other fixture.

Suitable for use in aerospace, automotive, marine and rail manufacturing, the FSS has a positioning accuracy of ±0.05 mm, with a repeatability of ±0.02 mm. Actuators, each with an axially adjustable piston rod that can extend up to 1,000 mm and then be electro-pneumatically locked in place, adapt to the geometry of the workpiece, after which it is secured on the underside by vacuum cups on the top of the rods.

Modular and scalable, FSS can employ any number of actuators to form a support matrix to suit the shape and size of the part. Designed for robust industrial use and rated at IP67 to withstand coolant ingress, it delivers high retention forces in a compact footprint, avoiding vibration during heavy cutting operations, improving surface finish and increasing tool life.

The array of support rods and vacuum pads connects via the dedicated Roemheld control box to the machine tool’s CNC system over a high-speed Profinet link. When switching from one batch run to another, the next program automatically commands each actuator to adjust its height and lock into place, enabling software-driven, unattended changeovers.

In the UK and Irish markets, custom integration support is available for both manually loaded set ups and automated robotic cells through subsidiary company Roemheld (UK), based in Cramlington, Northumberland.
