The spindle (1) has a machine spindle (3), a release unit and a clamping unit (2) that are more adjustable between a clamping position and a release position. A clamping element realizes displacement radially to a spindle longitudinal axis (42) by an axial position change of a spring-loaded tension bolt (6). A tool or a tool support (7) is provided by a form closure and assigned to an axial position fixation of the spindle. The clamping element is designed as a check ball (13) that is supported in a ball cage (10) for interacting with a corresponding ball retainer (14) in the tool or holder. |
