INFLUENCE OF THE THERMAL RESISTANCE OF LIQUID COOLANTS ON THE MACHINING OF 12KH18AG18SH STEEL

摘要

The thermal analysis of the samples of liquid coolants (LC) and their concentrates was carried out with the use of a derivatograph. A new LC obtained as a result of modification of sunflower oil with triethyleneamine is compared with an LC based on petroleum. The results of comparative analysis of their lubricating properties are presented. It is shown that the samples based on modified sunflower oil exhibit higher thermal resistance and better lubricating properties.
