MODULAR VACUUM CLAMPING SYSTEM, VACUUM CHUCKS

Application with vacuumplate

The vacuum plate is particularly suitable for process-reliable clamping of flat metal workpieces with flat undersides on CNC machining centres and guarantees minimum set-up times. Even components that are difficult to clamp mechanically can be fixed uncomplicatedly, quickly, distortion-free and precisely with the help of the vacuum clamping system.

The vacuum clamping technology, vacuum clamps enable:

  • Short set-up times
  • High holding force
  • High precision

VACUUM PLATES AND VACUUM CHUCKS

Vacuum clamping plate with friction pads

The vacuum plate can be quickly attached to the machine table by means of clamping claws or a zero-point system.

The modular design ensures maximum flexibility through easy handling and any combination of the various product versions.

The complexity of the workpiece geometry, the type and method of machining and the horizontal forces to be absorbed determine the selection of the vacuum clamping plate version.

Exclusive SPREITZER features:

Optional friction pads result in a significantly higher absorption of transverse forces

  • High horizontal holding forces (up to 30% increase compared to vacuum plates without friction pads)
  • No additional force of the friction pads on the workpiece
  • Oil and ozone resistant, individually replaceable in case of wear
  • Activation and deactivation automatically via vacuum supply

Powerful components

Vacuum units can be used to generate a constant vacuum. The vacuum units have a liquid separator and an oil-lubricated vacuum pump. They serve as additional vacuum storage and can be used flexibly.

The vacuum generator works with compressed air. No additional connections are required on the machine.

SECURE CLAMPING OF COMPLEX WORKPIECES

When machining simple workpieces, a coarse grid dimension 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 grid dimension, this sealing cord can be positioned close to the openings and recesses. This seals them flexibly and minimises clamping force losses.

Vakuumspannung bei einem einfachen Werkstück

Simple workpiece

  • Geometrically simple structure
  • Few webs and recesses/openings
  • Bar width > 30 mm

Recommendation: grid size 25 x 25 mm

Vakuumspannung bei einem komplexen Werkstück

Complex workpiece

  • Geometrically complex structure
  • Many webs and recesses/breakthroughs
  • Bar width < 30 mm

Recommendation: grid size 12.5 x 12.5 mm

CLAMPING DEVICE

Clamping devices for aerospace

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 in demand.

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. Set-up time minimisation and the high degree of flexibility are additional arguments in favour of the vacuum clamping system.

MILLING THROUGH

Milling through a workpiece

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 carried out 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 drilled through without damaging the vacuum plate or the component itself.

Das Aufspannen von Aluminiumwürfeln

Efficient clamping of aluminium cubes

The application shows a vacuum plate in use on a CNC machining centre for metal processing. It is fixed on the machine table with the help of mechanical clamping devices. By using vacuum, the thin-walled underside of the workpiece can be clamped precisely and without distortion. This enables efficient 5-axis machining in one clamping.

The powerful AGG vacuum unit is used to generate the vacuum. Due to its compact design, it is mobile and can be moved ergonomically to the place of use by means of a handle and rollers.
