Turning with positive fit
The workpiece is stamped to produce a positive fit.
First of all, the workpiece is stamped in the stamping station. This positive fit now makes it possible to reliably clamp the workpiece with just a fraction of the previously necessary clamping force. Positive-fit clamping means that only minimum allowances need to be made for the clamping edge. In addition, the stopper tooth provides an absolutely precise reference point for re-inserting workpieces in the chuck with a high degree of repeat accuracy.
