Modern machining processes place heavy demands on
tool holding. Hydraulic chucks provides excellent clamping
characteristics combined with precise concentricity.
Furthermore, they enable a simple and fast tool change,
with the assistance of a special extraction key.
Turning the pressure screw generates sufficient pressure
in the pressure chamber resulting in an elastic deformation
of the clamping bush, providing powerful tool clamping
and precise concentricity. A safe and powerful fit is
guaranteed. If reduction bushes are applied that are able
to hold varying tool diameters, the tool application may be
extended without problem. If such bushes are not applied,
it is essential to observe the minimum clamping length!
Technology and advantages

A summary of the advantages:
• precise tool clamping with a maximum 3 µm deviation
from concentricity
• transmission of high torque through (excellent clamping)
optimised bush clamping
system
• high speed compatibility (no centrifugal
forces from clamping
segments)
• precise concentricity, therefore excellent
surface qualities and
dimensional
accuracy of the workpiece
• rapid tool change thanks to simple
operation of the clamping
screw
• optimal tool life
• hydraulic cushioning has vibration
absorbing effect
