Abstract
Modern engineering is focused on high-tech reliable automated equipment, the use of which is effective in the presence of high-quality wear-resistant tools. The article discusses the results of the study DLC-films end mills resistance in structural carbon and alloy steels processing. Coatings were obtained by cathodic pulse sputtering of graphite in a vacuum chamber. There are presented results of the study of the influence of diamond-like (DLC) films on the end mills wear resistance. It is shown that the application of diamond-like films on the end mills uniquely increases the resistance of the mills, but differences in this issue for mills of different diameters are revealed. The results of the study of the influence of the pulse frequency of spraying in the formation of the coating on the cutting properties of end mills are also presented. It is established that the increase in the pulse frequency during cathode sputtering of graphite in vacuum when applying a diamond-like film leads to an increase in the resistance of end mills. The results of this work can be useful in Metalworking of structural steels with end mills.
