Tokarchuk Oleksii – PhD, Associate Professor of the Department of “Processes and Equipment for Processing and Food Productions named after Prof. P.S. Bernik" of the Vinnytsia National Agrarian University (3 Solnechnaya St., Vinnytsia, 21008, Ukraine, e-mail: tokarchyk@vsau.vin.ua).
As a result of intensive development of industries of engineer, construction of modern wares include a lot of details from new materials, majority of which are difficult in treatment. Mainly they are stainless, heat-resistant and heatproof materials, treatment of which by both pressure and cutting in comparising whith treatment of ordinary construction steel, is substantially complicated. At the same time, among all types of processing of stainless and heat-resistant steels and alloys, the most difficult and low-productive operations are the manufacture of skrew-threaded holes with taps. Tapping of internal screw-threads even in conventional structural steels is one of the most difficult machining operations because of unfavorable conditions of the formation and placement of chips, insufficient strength of the tap, complications of the supply of coolant to the cutting zone, etc.
The complex of known measures aimed at increasing the stability of taps and their reliability and creating new instrumental materials, improving the design and optimizing the geometry of the cutting part of the taps, improving the quality of the working surfaces, the application of new types of cooling and optimal regimes do not solve the final issue of high-performance and high quality manufacturing of threaded openings in stainless and heat-resistant steels not only on highly automated equipment, but also on ordinary.
