摘要： A collet chuck assembly includes a mount, a selectively-axially-movable collet closing sleeve, and a multiple-segment collet head. The collet head includes two axially-spaced outer circumferential cam surfaces that engage two axially-spaced inner circumferential cam surfaces of the closing sleeve. A quick-release cap attached to the mount includes two inwardly-radially-extending tabs that engage two outwardly-radially-extending lips of the collet head to prevent the collet head from moving axially relative to the cap. Flat resilient collet seals are disposed between each set of adjoining collet segments to prevent debris from getting into the collet chuck assembly between the segments. The collet seals maintain full-surface contact with adjoining segments even when the collet head is fully opened. A slinger bore formed in the cap directs debris radially-outwardly out of the collet chuck assembly.
