This page is used to quickly review the clamping force trend at different spindle speeds. It is not a production safety calculator and does not replace on-site testing.
FAQ
Why does higher spindle speed reduce clamping force?
When a chuck rotates at high speed, top jaws and soft jaws generate centrifugal force. Higher speed increases that force and reduces effective gripping force, especially near the maximum speed.
Can this result be used directly for production?
No. The result is not verified by testing and is only for chuck selection and trend reference. Actual production must be verified with a gripping force tester and checked against the workpiece, jaws and machine condition.
How is the static clamping force calculated?
The tool estimates it from the selected chuck, matched cylinder area, hydraulic pressure, allowable drawbar force and maximum clamping force, with the chuck allowable drawbar force used as the cap.
When should speed be reduced or the workholding plan changed?
Reduce speed or change the plan when remaining force is low, speed is close to the limit, the workpiece is thin, jaws are heavy or cutting load is high.
When is collet-style gripping better for small-diameter parts?
For small-diameter batch parts, surface protection or more uniform wraparound contact, a collet chuck or rubber-flex collet chuck can be reviewed, while checking clamping range and cutting load.
Why can some solid chucks not calculate static force automatically?
Some solid chuck records do not yet have reliable matched cylinder area data. In that case, use another calculable model or submit the chuck and cylinder data for confirmation.
