Vacuum clamping technology
We offer tailored solutions in the field of vacuum clamping technology and vacuum clamping plates. Reliable clamping of flat, planar metal workpieces, minimal setup times, and distortion-free machining, for example, in CNC machining centers.
Modular Vacuum Clamping System, Vacuum Clamp
The vacuum plate is particularly suitable for process-reliable clamping of flat metal workpieces with flat undersides on CNC machining centers and guarantees minimum setup times. Even components that are difficult to clamp mechanically can be fixed easily, quickly, distortion-free and precisely with the help of the vacuum clamping system.
The vacuum clamping technology, vacuum clamps allow:
- Short setup times
- Large holding force
- High precision
Flexible Design of a Complete Vacuum Clamping System
Vacuum plates
The vacuum plate can be quickly secured to the machine table using clamping claws or a zero-point clamping system.
The modular design ensures maximum flexibility through easy handling and the ability to combine the various product versions in any way.
The complexity of the workpiece geometry, the type of machining, and the horizontal forces to be absorbed determine the selection of the vacuum clamping plate version.
Exclusive spreader features:
Optional friction islands result in significantly higher absorption of transverse forces- High horizontal holding forces (up to 30% increase compared to vacuum plate without friction islands)
- No additional force effect of the friction islands on the workpiece
- Oil and ozone resistant, individually replaceable in case of wear
- Activation and deactivation automatically via vacuum supply

Vacuum unit and vacuum generator
Powerful system components
Vacuum units can be used to generate a constant vacuum. These vacuum units are equipped with a liquid separator and an oil-lubricated vacuum pump. They serve as an additional vacuum reservoir and can be used flexibly. The vacuum generator operates using compressed air. No additional connections to the machine are required.Securely clamp complex workpieces
When machining simple workpieces, a coarse pitch is sufficient. Complex workpieces with openings must be additionally sealed with a sealing cord at the corresponding points to ensure the system vacuum. When using a fine pitch, this sealing cord can be positioned tightly against the apertures and recesses. This seals them flexibly and minimizes clamping force losses.
Simple workpiece
- Geometrically simple structure
- Few webs and recesses/breakthroughs
- Bar width > 30 mm
Recommendation: grid dimension 25 x 25 mm
Complex workpiece
- Geometrically complex structure
- Many webs and recesses/breakthroughs
- Bar width < 30 mm
Recommendation: Grid dimension 12.5 x 12.5 mm
Clamping device
Clamping device for aerospace
The sometimes very complex workpiece geometries in the aerospace industry usually require a special clamping solution adapted to the application. Maximum precision and gentle machining of the workpiece are particularly required. Within the scope of special project planning, we have already developed successful solutions for customer-specific projects on several occasions. With the vacuum plate, even very thin workpieces can be fixed without damage and with process reliability. Minimized setup times and the high degree of flexibility are additional arguments in favor of the vacuum clamping system.Milling through
Milling through a workpiece with vacuum plate and grid table suction cups
The use of grid table suction cups makes it possible to produce apertures when machining workpieces. In the first step, machining is performed with small height tolerances on the workpiece clamped on the vacuum plate. In the second step, the grid table suction cups are inserted directly into the grid of the vacuum plate and the suction cups are arranged according to the position of the drill holes. In this way, the workpiece can be pierced without damaging the vacuum plate or the component itself.Clamping
Efficient clamping of aluminum cubes
The application shows a vacuum plate in use on a CNC machining center for metalworking. It is secured to the machine table using mechanical clamping devices. The use of vacuum allows the thin-walled underside of the workpiece to be clamped precisely and without warping. This enables efficient 5-axis machining in a single setup. The powerful AGG vacuum unit is used to generate the vacuum. Thanks to its compact design, it is portable and can be ergonomically maneuvered to the work site using a handle and casters.
