Clamping force-RPM diagrams
Clamping force/RPM curves have been calculated using the
corresponding standard top jaws (stepped jaws and monoblock
jaws). In the determination process, the maximum actuating force
was applied and the jaws were set flush with the outer diameter of
the chuck.
The chuck is in perfect condition and lubricated with SCHUNK
LINOMAX plus special grease.
If one or more of these prerequisites is modified, the graphs will
no longer be valid.
