Finding the right system

systems

1
What are the maximum dimensions of the workpieces that you want to machine?
Example:
Square: Up to a maximum of  120 x 150 mm (steel)  approx 17 kg
Round: Up to a maximum of ∅ 170 x 100 mm (steel)  approx 17.8 kg

2
On the basis of 1, look for the suitable system size in the following table. 
Example: The GPS 120 system is the most likely for consideration.

weight

3
Based on the maximum weight of the workpiece, define the suitable size for the pallet/reference element.
Example: Max. weight < 20 kg gives a GPS 120 reference system.

It is also possible to combine several clamping systems, with manual or automated system adapter.
