Annotation

Introducing chipless taps into production it is necessary to take into account factors arising from the specifics of the method and factors affecting economic efficiency.
Significant effect from the introduction of the machine method of manufacturing threaded holes in stainless steels with brushless taps can be obtained only if the complex of measures is observed, related to the choice of the optimum hole diameter and the quality of preparation of the hole for the thread, the choice of mounting the tap on the machine, the speed of thread extrusion, coolant equipment and others.
A new contour design has been proposed in the paper to prevent damage to the instrument for the manufacture of internal threaded holes. In addition, the design allows to replace quickly the instrument to another size.
The designed construction of the cartridge ensures the centering of the tool over the hole being machined and ensures the transmission of torque of the required size. Analytical dependencies and computational schemes that ensure the operability of the device are derived.

Keywords: carving, safety cartridge, taps, stainless steel, torque.

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering  and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
