6.3 Gripping Force

The following graph shows the gripping force of the rotating chuck equipped with the standard
soft jaws.

This diagram is drawn in the condition that the jaw stroke is middle and using standard top
jaws.
Each diagram contains the lines indicating the claming force when the input force is lower than
that of maximum.
Refer these diagrams in case that the lower input force is necessary in relation to the character
of a work piece.

6.4 Standard Soft Jaws
