MBS-Diaphragm MDR

The diaphragms MDR got used in association with SDR top jaws on diaphragm-chucks without through bores (MBS-DL, MBS-DZ). The top jaws got screwd in from the backside on the diaphragms. This has the advantage that no bores at all are existing in range of the clamping diameter, which could disturb a more exact clamping result.
