Retightening the Collet

Continuous milling will cause the collet to become loose, making it easy for the milling bur to come off. Periodically retighten the collet.

Recommended Interval for This Work

  • Once a month, or when the total work time of the spindle exceeds 200 hours (with slight variation depending on the work situation).
