The paper discusses the results of comparative tests of the period of tap resistance in various technological environments. The workpieces were processed in the medium of industrial oil I-30 with using a 10 and 20 percent solution of the metal-coating additive “Valena SV” in the same oil. The tests were performed on M10×1 taps made of high-speed steel of the R6M5 brand during the production of through threaded holes in samples made of steel of the Steel 40X brand. The cutting speed varied from 5.7 to 11.1 m/min at the rotary speed of the tool ranging between 180 and 355 rpm. Based on the experimental material, a regression model of the relationship between the relative wear resistance and the additive concentration, and cutting speed has been determined. The author has evaluated the model adequacy and the convergence of the experimental and calculated data. It has been found that at a cutting speed of 11.1 m/min and an additive concentration of 20%, the relative wear resistance of the taps increased by 3.1 times. The results obtained testify to the eff ectiveness of the composition and confi rm the hypothesis of an increase in the wear resistance of the taps in the medium of metal-plating lubricating-and-cooling liquids.

Cutting Speeds

Machining is a popular and versatile manufacturing process that is widely used in today’s industry when producing metallic parts; however, limited tool life can make this an expensive and time consuming fabrication technique. Consequently, methods that decrease the rate of tool wear and, thus, increase tool longevity are a vital component when improving the efficiency of machining processes. To this end, cryogenically treating cutting tools (especially high-speed steel tooling) is becoming more commonplace since research has shown that the treated tooling exhibits significantly higher wear resistance. At this point, however, the effect of cryogenic treatments on ceramic tooling has not been established. Considering this, the research herein presents a feasibility study on the effectiveness of using cryogenic treatments to enhance the wear resistance of WG-300 whisker-reinforced ceramic cutting inserts. To begin, the effect of the cryogenic treatment on the insert’s hardness is examined. Subsequently, tool wear tests are conducted at various cutting speeds. Through this study, it is shown that cryogenically treating the ceramic inserts decreases the rate of tool wear at each of the cutting speeds that were tested. However, the degree of wear resistance introduced by cryogenically treating the inserts proved to be highly dependent on the cutting speed, with slower speeds exhibiting greater improvements. Thus, based on this initial study, the cryogenic treatment of ceramic tooling appears to produce beneficial results, potentially increasing the overall efficiency of machining processes.

Deep Cryogenic Treatment

High speed steel (HSS) is a very important industrial tool material and has been constantly improved for different wear resistance applications and cutting tools, i.e. drills, milling cutters, hobs and for the cutting tools in which the economical cutting speed is too low for choosing the carbide tools. The properties of HSS depend significantly on the parameters of the conducted heat treatment. In this paper, the influence of deep cryogenic treatment in combination with nitriding of metallurgical powder metallurgy HSS on the wear resistance was measured. Additionally, the cutting performance in a single point cutting tool machinability test at the configuration of the dry low-speed turning of steel was investigated. The results showed that deep cryogenic treatment itself, and in combination with nitriding, resulted in the reduction of the wear rate. The results of the single point cutting tool machinability test showed that deep cryogenic treated and nitrided HSS inserts performed worse than the classically heat-treated inserts and deep cryogenic treated HSS inserts exhibited approximately the same flank wear as the nitrided ones.
