OUTLINE OF SYSTEMS C-5
4.3 Maximum Allowable Chuck Speed
The maximum allowable speed is the spindle speed at which the gripping force is 1/3 less than the
gripping force obtained when the spindle is not rotating.
The maximum allowable spindle speed is determined under the following conditions:
<Conditions>
• Standard soft jaws are used.
• The master jaw is located at the center of the jaw stroke.
• The soft jaws are positioned so that the outer periphery of the soft jaws is on the chuck
periphery.
WARNING
If the maximum allowable cylinder speed is lower than the maximum
allowable spindle speed, the spindle must be rotated at a lower speed
than the maximum allowable cylinder speed.
