Flexible layout of a complete vacuum clamping system
Practical application examples
Clamping device for the aerospace industry
The often very complex geometry of parts used in the aerospace industry frequently require the use of lamping solutions matched specifically to the application. Maximum precision and careful handling of the workpieces are also very important.
Spreitzer has already developed special solutions for many customer-specific projects. With the vacuum plate, it is possible to clamp even very thin workpieces securely without damaging them. Further arguments in favour of vacuum clamping systems are the reduced set-up times and the high level of flexibility.
Milling with vacumm plate and suction blocks
The use of grid table suction blocks makes itt possible to machine holes and apertures in workpieces. For this, the workpiece is clamped on a vacuum plate / vacuum chuck with very low height tolerances for the first machining step.
For the second step, the grid table suction blocks are placed directly in the slots of the vacuum plate and the suction blocks are positioned to match the positions of the holes. The holes can now be drilled through the workpiece without damaging the vacuum plate or the actual workpiece.
Efficient clamping of aluminium cubes
This application shows a Vacuum-Plate in use on a CNC machining centre. It is secured to the machine table with the aid of mechanical clamping elements. The use of vacuum makes it possible to clamp the thin bases of the workpieces precisely and without distortion for five-axis machining without repositioning.
The vacuum is generated by the powerful vacuum unit AGG.The compact design makes it suitable for mobile use. It has castors and a handle by which it can be moved ergonomically to the desired position.
