Abstract
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 M10х1 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 effectiveness of the composition and confirm the hypothesis of an increase in the wear resistance of the taps in the medium of metal-plating lubricating-and-cooling liquids.
