Diaphragm chuck MBS-Z The MBS-Z chuck series is a power-operated chuck with coolant through the middle. For actuation of the chuck, a external clamping cylinder got used. Workpieces could get clamped sensitive or with higher clamping force according to the version and adjustment of the clamping cylinder. With the MBS-Z chuck associated with a clamping set, a high precise clamping got realized. Further it is possible, to use clamping sets for different workpieces which are requirering high accuracies.
