ABSTRACT:
A rotatable tool-holder turret for lathes, work-centers and the like, comprises a stationary base body with a cavity which extends along a longitudinal axis, a tool-holder table rotatable relative to the stationary base body, an element with teeth for locking and releasing the rotatable table relative to the stationary body, a drive mechanism for moving the table between working positions spaced angularly around the longitudinal axis, as well as a compressed air operated cylinder-piston for moving the locking and release element axially. The turret includes a mechanism for amplifying the axial thrust generated by preloaded springs, the mechanism holding the locking element mechanically in the position in which the turret is locked, by a plurality of balls which are movable radially relative to the longitudinal axis of the turret and which can be inserted between and released from facing walls, including at least one conical wall of the locking element and of a wall of a second, stationary tubular element.
