Advanced Engineering Letters volume: 1 number: 1 startpage: 8 endpage: 15 Keywords: Friction coefficient, cutting lubricant, temperature, tribological tests, epilam films eng info:eu-repo/semantics/article 2022 Abstract: The article discusses the mechanism of action of the epilam film during the operation of epilated drills and the influence of cutting conditions, processing conditions on their condition. Tribological tests were carried out using a special installation, where the test conditions are close to the conditions characteristic of the drilling process. Based on the results of the experiment, it was found that the effectiveness of epilam film directly depends on the cutting speed, which determines the temperature in the contact zone. Research has shown that use of oil-based LCTF MR-7 (МР-7) has the best effect on the state of epilam coating.
