OIL LUBRICOOLANTS FOR BROACHING OPERATIONS WITH IMPROVED TRIBO-ENGINEERING AND COOLING CHARACTERISTICS

Abstract

The paper objective is to test the developed lubricoolants of domestic production for broaching operations instead of imported analogues. The results of comparative laboratory tests of new technological lubricoolants Rosoil-V9 and Rosoil-423M for broaching operations, which are analogues of imported coolant, are presented. Laboratory tests are carried out in the Laboratory for Testing Technological Lubricants of Self-supporting Creative Center of Ufa Aviation Institute. Tribo-engineering properties are determined on a four-ball friction machine according to GOST 9490-75; cooling characteristics are determined on UZS-2 installation. The physicochemical properties are evaluated by standard test methods. As a result of the conducted research, it is found out that the physicochemical properties of Rosoil lubricoolants are similar to imported ones, and in terms of tribo-engineering and cooling characteristics, Rosoil lubricoolants are better than imported analogues.
