Abstract

1,097,602. Tapping. NAUTCHNO - IZSLEDOVATELSKI I PROEKTNO - KONSTRUKTORSKI INSTITUT ZA METALOOBRABOTVASHTI MASHINI I INSTRUMENTI. March 24, 1965, No. 12583/65. Heading B3N. A method of tapping comprises holding and rotating the tap at both ends in a tapping machine, and feeding the tap, or work, axially during such rotation. The tap comprises hexagonal ends 3, 4, Fig. 3, guiding portions 5, 8, a cutting portion 6, and a sizing portion 7. The tapping machine comprises two spindles 17, 18, Fig. 4, by which the tap 1 is rotated, the spindles being rotated by an electric motor 11, through a gear-box 12 and a differential mechanism 15. The spindles are carried on a slide 21 fed by a screw and nut 16 driven by the motor through a reversible mechanism 13, the workpiece 2 being fixed. When the work is to be fed, the latter is carried on a slide moved by the screw- and-nut 16, and the tap spindles are fixed.
