HQJC chucks use reaction force to grip the workpiece or jaw forming ring to secure the jaws.
The jaw clamping is not complete in the empty gripping state when no gripping reaction force is generated.
Rotating the chuck at 100 r.p.m. or more is dangerous because the jaws may be scattered by centrifugal force.
Do not rotate at speeds higher than 100 r.p.m. in an empty grip condition.
Also, depending on the situation, install an interlock or similar device on the machine to which the jaws are to be attached.
