Modern high performance machining needs a permanent advancement of all involved components. Succeeding generations of tool machines and machining tools are enabling therefore steadily shorter processing times on less average unit costs. But one weakness remains: The workpiece clamping! It gets more difficult to accomplish the current requirements with regular clamping systems. With our diaphragm chuck series MBS, we are covering a lot of requirements of present-day's clamping systems!

High process safety Short setup time Variable adjustable clamping force, also while the spindle is rotating. Accuracy < 2 µm Accuracy by changing the clamping diameter < 3 µm Maintenance and lubrication free for lifetime Long tool life No unprotected guides Sealed against pollution Wear resistant Centrifugal power resistant Speed up to 11,000 Rpm. Big jaw stroke Clamping force between 50 and 6,230 daN Compatible to MC jaw chucks Coolant through as standard Usable with MIS-mandrel system

In rotating applications with a required passage, the central air connection can be disturbing. Here we offer you the so-called backported chuck. This type of chuck is not supplied with compressed air through an air tube, but by bores, which are attached at the rear of the chuck. The compressed air required for operation is conducted either through holes in the machine spindle to the adapter plate (full through) or through an air tube that is connected to the adapter plate (partial through). From the adapter plate the air is routed through holes in the rear side of the chuck. Furthermore, this enables the installation of part stops or part ejectors in the chuck center. Due to the large number of possible adaptions, we are having this chuck type not individually in our catalog. Our sales technicians are happy to advice to your clamping problems.

Features of MBS-Chucks

Basic for special clamping systems

Special clamping devices for your specific requirements could get realized very well out of our MBS series because of its modular setup and the brilliant features. In the above showed chuck for example a mandrel got integrated. Because of this, several operations (ID and OD clamping) could get realized with one clamping system and the production process has been improved greatly.

The MBS chucks are sealed and do not have any jaw guides. As a consequence of this, they are especially wear-resistant and suitable for machining of abrasive materials (e.g. carbide metal, ceramics). On thin-walled parts a surrounding clamping and a very sensitive adjustment of the clamping force are

MBS: Highlights

granting a non-deforming machining of the parts. The chucks are consisting of following, essentially components (MBS-L depicted):


The MBS chuck opens for OD-clamping when the piston is moving forward, either by air pressure or by drawtube force. The chuck closes done by the re-deformation of the elastic diaphragm, depending on cases of applications additionally provided by pneumatic or draw tube actuated movement of the piston. At this, the clamping force can get featured very sensitive and flexible. For ID-clamping the function is reversed.

The MBS diaphragm-clamping system is consisting of following components:

Chuck body assembly Clamping set (Diaphragm / Top jaws / part stop)

All diaphragm chucks have a pull down effect at clamping. For an exact axially position of the workpiece, we recommend axial part stop. The MBS clamping system could get equipped with a part stop spider / part stop plate with mounted stop pins or stop plates. For coolant supply through the chuck, nozzles are getting screwed-in the part stop spider. The coolant gets supplied out of the backside of the chuck to your workpiece. That is a big advantage especially at ID grinding or at the machining of small bores. On part families which have to clamped with a different number of jaws (e.g. showed in the right upper corner 3 and 5 jaws) or different diameters or rather axial clamping position, it‘s very easy to change the whole clamping sets and reach a very high changing accuracy. A gimmick for clamping the ID, our mandrel system MIS is available, which got actuated by the chuck body assembly MBS.

* The usable through bore is smaller because of the actuating screw, shown at MBS-DL or MBS-DZ

The diaphragms MDR are used in association with SDR top jaws on diaphragm chucks with through bore (MBS-DL, MBS-DZ). The top jaws got screwed 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. The diaphragm is on request also available with another number of jaws.

Top jaws SMK (without through bore)

The top jaws SMK are used in association with MMK diaphragms on chucks without through bores (MBS-L, MBS-Z) or vices (MBS-N). The jaws are made of steel and could get hardened inductively. The top jaws got screwed in from the front on the diaphragms, this grants a fast change-over of the top jaws. On chuck sizes 80, 100 and 125 1 Set top jaws consists of 3 pieces. From chuck size 150 and greater 1 set top jaws consists of 6 pieces

The top jaws SMR are used in association with MMR diaphragms on chucks without through bores (MBS-L, MBS-Z) or vices (MBS-N). The jaws are made of steel and could get hardened inductively. They don't have fastening bores in the clamping range whereby a realization of ideal clamping solutions over the whole clamping diameter got granted.

As part stop, a part stop spider got mounted on the diaphragm. On this part stop spider, bolts, plates or special shapes could get fastened, which are granting an exact axial positioning of the workpieces.

Part stop spider ASS

Part stop base plate ATR

By option, the part stop base plate ATR could get screwed in the chuck body, if caused by technical reasons a part stop spider is not possible or useful. By using the part stop base plate ATR fixed, sealed bolts are sticking out the diaphragm, which are servicing as axial part stop.

Coolant Nozzle KMD

To supplying coolant targeted to the position of machining, a nozzle could get screwed in the front of the chuck. There are several kinds of nozzles (after building size and impact way), which are available in stock!
