Improving the quality and efficiency of secondary
machining operations . . . .
through high workpiece concentricity, and reliable
chuck performance. For thirty years MicroCentric
has supplied innovative chucking products to
the metalworking industry according to this
principle. The MBS high precision Diaphragm
Chucks are the latest advance of MicroCentric's
workholding technology. MBS chucks are available
in both self-contained and draw tube operated
designs. All models are double acting, meaning
they are capable of both OD and ID clamping,
and are available for rotating and stationary
applications.

The MBS Concept . . . .
The diaphragm of the MBS chuck, without an applied
force, is in a neutral position. When a force
is applied by either the internal piston, or the
draw tube, the diaphragm is expanded or contracted.
A force in the +Z axis opens the chuck. A force
applied in the -Z axis closes the chuck, or clamps
the workpiece in an OD chucking application. MBS
Chucks do not rely solely on the spring force
of the diaphragm to generate clamping force on
the workpiece. Additionally, MBS chucks feature
a greater jaw stroke than conventional diaphragm
chucks due to the unique MBS diaphragm design
that incorporates two pivot points. The MBS design
provides load clearance up to .060" (1.5mm).

and have no moving parts to wear out or become
contaminated by chips and swarf) |
| • |
Large jaw opening for maximum load clearance |
| • |
High speed capability up to 10,000 rpm |
| • |
Variable clamping force makes MBS chucks ideal
for both roughing and finishing operations |
| • |
6 jaw design enables MBS chucks to clamp
fragile workpieces with minimal distortion |
| • |
Clamping force can be varied during the machin
ing machining cycle to maintain consistent grip
on the workpiece |
| • |
Hi-Lo clamping capability |
