Diaphragm chuck MBS-L

The MBS-L chuck series is a pneumatic operated chuck with a built in air cylinder and coolant through the middle. For actuation of the chuck, compressed air got supplied via an air tube version 50. By reason of variation of the air pressure, workpieces could get clamped very sensitive and non-deforming according to several cases of applications, also with higher clamping forces. With the MBS-L 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.
