Abstract

The influence of lubricating and cooling liquids on the working and operational properties of high-nitrogen corrosion-resistant steels is investigated. It is established that during stabilization of stationary potentials of steels with machined surfaces, repackaging of 12Kh18АG18Sh occurs (increase of potential values from -330… -340 mV to 40… 60 mV). The use of lubricating cooling liquids (LCL) containing sunflower (LCLs) or rapeseed oil (LCLr), together with changing machining conditions, can affect the change in the morphology of chips of hart-to-cut steels. Reducing the size of the chips avoids damage to the machined surface and eliminates the use of imported high-value chip breakers. The analysis of cutting products and machined surfaces can allow you to choose the optimal parameters of the cutting process, as well as the cutting tool. It is established that the intensity of wear (P = 500 N) in comparison with the industrial oil I12A with the application of LCLs is lower by 45%, and at LCLr 35%
