Application of lubricant-cooling agents for cutting difficult-to-machine materials.

The article is devoted to the study of the efficiency of lubricant-cooling agents and, in particular, liquid coolants (LSS) when cutting heat-resistant, corrosion-resistant and other difficult-to-machine materials. The main reasons for their low efficiency are their high chemical resistance (the impossibility of the formation of oxide and other protective films), high specific pressures and temperatures at the contact zones of the cutter and chips. In accordance with modern concepts, effective lubricant-cooling agents in this case should contain such substances that would be easily destroyed in the tribological conjunction zone into particles and free radicals that are chemically active with respect to these materials. The research was carried out with various operations of mechanical processing of difficult-to-machine materials, the results of experiments are presented. [ABSTRACT FROM AUTHOR]
