Date Oct. 14, 1993.A spindle head has a housing accommodating a faceplate rotatable in a circular slideway. A spindle quill is mounted in the faceplate eccentrically to its axis of rotation and rotatably in a circular slideway. The spindle head also has respective turning mechanisms of the faceplate and the spindle quill, and transmitters of their angular position which include rotors and stators interacting therewith and associated with the machine control system through a cable. The rotor of the faceplate angular position transmitter is connected to the faceplate through a rod accommodated in the hollow space of the spindle quill turning mechanism, and the stator of the transmitter is secured on the spindle head housing. The rotor of the spindle quill angular position transmitter is connected to the spindle quill through a rod accommodated in a hollow layshaft, and the stator of the transmitter with the cable end secured thereon is mounted on the faceplate. The opposite cable end is connected to the machine control system through a transfer device. The drive shaft of the spindle quill turning mechanisms is accommodated inside a double-gear cluster that interconnects the spindle to its rotation drive.
