One of the most important criteria when selecting a reference system is the repeatability of positioning in the process chain. The repetitive accuracy (same pallet on same fixture) is about 2 µm for standard reference systems. The changing accuracy (same pallet on various fixtures) is 8 - 15 µm.
Although this is sufficient for many manufacturing processes, it is not acceptable when manufacturing highly precise small parts. In this case, tolerances of < 5 µm are required.
With standard reference systems, the maximum allowable tolerance in the process chain (from machine to [measuring] machine) is already reached or exceeded at re-clamping without manufacturing failure.
Carl Hirschmann Clamping System µ-PrisFix-Nano guarantees an average repetitive accuracy of ≤ 0.1µm (same clamper) and a changing accuracy (from clamper to clamper) of ≤ 0.5µm.
The repetitive and changing accuracies were tested and confirmed by the Federal Institute of Technical Physics as part of a development project. Test results are available upon request.
