摘要： Cutting tool made as gang tools is located round the rotor and is fixed in position on the machine bed. The rotor that carries work spindles imparted rotation at a cutting speed from the main motion drive through the central gear wheel, has a rotativemotion drive of its own to impart circular feed motion. The circular feed motion drive of the rotor comprises the selfbraking single-worm gear whose worm wheel is positively locked-in with the rotor, while the worm is kinematically assocated with the central gear wheel so that, regardless the direction of the rotor rotation, the tooth contact in the single-worm gear remains unaffected with the result that high rigidity of the system ''''tool-spindle-rotor'''' is established in the course of cutting.

摘要： Article-supporting spindles rotatable at a cutting speed from the main drive are mounted on a rotor associated with an angular feed drive and uniformly angularly spaced on this rotor. The cutters associated with radial abutments are mounted in cutter blocks rigidly mounted on the framework of the machine tool and are also uniformly angularly spaced about the rotor. The angular spacing of the cutter blocks is different from the angular spacing of the spindles by a value which is a multiple of the ratio of the angle of engagement of the cutter with an article at working of the latter to the number of the cutter blocks, whereby in operation of the machine tool the angular feed of the rotor brings successive articles into contact with the cutters in sequential fashion. The multispindle machine tool can be successfully employed for working various articles shaped as bodies of rotation, where requirements as to the accuracy of the size and shape of the articles, as well as to their surface finish are particularly strict.
