Abstract: A tool-carrier turret having a high displacement speed, particularly for lathes and work centres the rotatable table of which is provided with a plurality of supports for fixed tools and a plurality of supports for tools of the rotating type. The turret is provided with a single motor for driving the rotating tools and for displacement of the table through respective mechanical transmissions, as well as a device for commuting the drive from the electric motor to one or other of the mechanical transmissions in synchronism with the device for locking and releasing the table. An encoder is connected to the drive shaft of the rotatable table via a mechanical coupling which makes it possible to obtain a complete rotation of the encoder shaft for each angular displacement of the table between two successive tools.
