Abstract

The study analyzes the impact of different technological agents on the surface purity during metal turning. New technological lubricants consisting of organic compounds are studied. In the agents nanodiamond powder is used to intensify the metal turning processes. The agent is fed into the sample’s turning zone while affecting the purity of the surface. The impact of the agent on the surface layer quality in the processing of heat-resistant steels and alloys is investigated. The optimal composition of the agent is revealed when turning one or another material. The tests established the positive effect of the agent on the quality of the treated surface and other parameters of the turning processes of various metals and alloys.

Highlights

Technological advances in the most important branches of modern mechanical engineering are associated with more and broader application corrosion-proof, heat-resistant and another hardly processed steels and alloys [1,2]
At N07750 dry turning the purity of the surface increases as the cutting rate increases
The use of water as lubricating-cooling process agents (LCPA) contributes to the intensive formation of growth, frequent disruptions from the front surface along with particles of the cutting tool material and, as a result, the deterioration of surface roughness in the entire range of cutting rates

Summary

Introduction

Technological advances in the most important branches of modern mechanical engineering are associated with more and broader application corrosion-proof, heat-resistant and another hardly processed steels and alloys [1,2]. This puts forward the task of developing, investigating and introducing highly efficient formation processes using the latest advances in physics, chemistry and related sciences. Cutting rate can be reduced up to 20 times and more [5], [6] This results in a sharp increase in part processing time and a decrease in processing productivity [7]. One of the most important productivity-enhancing reserves and improving cutting technology is the use of efficient lubricating-cooling and protective process agents [8]
