Technical Article: The run-out improver

A new EMUGE clamping principle tolerating relatively large deviations of boreholes, was presented for the first time at the EMO. "The clamping element compensates minimal tapered boreholes of rotation symmetrical workpieces. Run-out accuracies of less than 5 µm can be achieved.

Even internal splines can be clamped." Clamping specialist Günter Ehras explains the advantages of a merely mechanical concept - also versus hydraulic expansion chucks.
