Specify a spindle speed limit that is lower than the lowest of
the individual allowable speed limits for the chuck, cylinder,
and fixture.

Before starting the spindle, secure that the workpiece and
rotary tool are clamped correctly. For center-work
machining, also check that the tailstock spindle center is
pressing the workpiece correctly.

1.
As the spindle speed increases, centrifugal force acts on
the chuck jaws reducing the chuck gripping force.
Measure the chuck gripping force at regular intervals using
a gripping force meter to secure that the required gripping
force is maintained. If it is not, contact the chuck
manufacturer and the cylinder manufacturer.

The relationship between gripping force and spindle speed
varies depending on the size, shape and mounting
conditions of jaws and workpieces, cutting conditions, and
the chuck used.

3.
When machining, measure the chuck gripping force applied
during spindle rotation at the actual machining speed using
a gripping force meter. If the required gripping force is not
maintained, change machining conditions such as the
chucking pressure, spindle speed, feedrate, and depth of
cut.
