Abstract
The chuck includes a slitted body with an axial bore that holds the tool shank during rotation of the chuck. A gripping sleeve applies compressive pressure via cam elements to reduce the diameter of the axial bore. A spring biased locking sleeve can activate locking elements to lock the gripping sleeve to the body member in the locked position. An engagement mechanism connects the chuck to a drive spindle and also has a mounting mechanism for facilitating automated mounting of the chuck to a drive spindle.
