FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used in thread cutting devices. Method of thread cutting includes supply of shaft with cutting tool to part hole by screw movement, creation of pulling force, thread cutting by self-tightening of tool and withdrawal of the latter from hole. Screw movement of the shaft is created by at least one worm gear, in which the worm is made on the shaft, and the worm wheel is decelerated. Worm wheel is decelerated by means of a spring pressure retainer. Cutting tool feed and retraction is performed by means of worm wheel rotation. Worm wheel is also rotated by a stepper motor. Worm wheel is decelerated also by means of electromagnet. Cutting tool feed and retraction is performed also by another worm gear.
EFFECT: simplified design of the device, expanded its operating performances.
