ABSTRACT:
A spindle head for a tool turret has a housing in which a spindle is mounted rotatably. A rotation lock for the spindle includes a bushing arranged to be longitudinally slidable but nonrotatable on the spindle. A securing element is provided on the bushing. The bushing securing element, in its work setting, engages a securing element on the housing, limiting the axial movement of the bushing relative to the housing in the direction of the form-locking engagement of the two securing elements, and can be disengaged by an axial movement of the bushing counter to the force of a prebiased spring in a direction away from the housing securing element. At least some of the cooperating surfaces of the securing elements in the work setting are inclined with respect to the axial direction to a degree that excludes self-locking.
