MAPAL says its new HTC (High
Torque Chuck) range of chucks
offers machine tool users the fast,
convenient and safe tool changes
offered by hydraulic chucks in
applications
where it would
previously have
been necessary
to use
alternative clamping technologies.

The chucks are said to be suitable
for use in milling and precision
drilling operations and for rough
machining, heavy duty metal cutting
and other demanding applications.

System rigidity is combined with a
high radial run-out accuracy of 3
microns or better. Bending resistance
is said to be typically 1.4 times that of
comparable shrink chucks and torque
transmission capacity up to 20%
greater.
