Universal Holding Fixtures
Universal holding fixtures do not hold the workpiece over its entire surface, but typically use round vacuum suction cups. These suction cups adapt actively or passively to the local curvature of the component. In addition, each individual suction cup is raised to the corresponding height by an actuator, at least in one dimension. This also replicates the surface of the part to be held, but only at typical grid intervals of 200 mm to 500 mm. A fixture of this type can be used for a family of parts and is therefore called “universal.”
Advantages of our Holding Fixtures

Active vs. Passive
Depending on the specific requirements and the underlying production process, a choice is made between active and passive universal clamping devices:
ACTIVE
fast and flexible
actuators with servo drive
BECKHOFF control with HMI
-
All actuators move synchronously, minimizing setup time
-
Retraction during milling to prevent collisions with the milling head
-
Use of actuators to actively pull or press the component into the desired shape

Individual Actuator Positions
If the parts are known at the start of the project, the actuators can be perfectly adapted to their shape and requirements.
The result: fewer suction cups, maximum holding quality, and precise, collision-free positioning near the milling tool.
The high flexibility of the system enables even simple grid positions to be implemented quickly and efficiently.
Various End Effectors
In addition to round suction cups, an individual hard tool can be mounted at any position. This makes component positioning very easy and provides improved support in monolithic areas to prevent vibration.
