Influence of Lubricating Liquid on the Formation of the Products of Cutting of 38KhN3MFA Steel

We study the morphology of chips formed in the course of turning of a blank of 38KhN3MFA steel on a turning lathe at a rotational speed of 200 rpm under the conditions without lubrication and with an addition of water or lubricating liquids (LL) containing sunflower oil. It was discovered that the a...

Zusammenfassung:	We study the morphology of chips formed in the course of turning of a blank of 38KhN3MFA steel on a turning lathe at a rotational speed of 200 rpm under the conditions without lubrication and with an addition of water or lubricating liquids (LL) containing sunflower oil. It was discovered that the addition of water and LL in the process of cutting promotes a decrease in the size of chip and leads to the transformation of its shape from flat to barrel-like. The application of LL makes the surface roughness nine times smaller than in the case of dry turning.
