One of the most important aspects of improving the quality of abrasive treatment is the improvement of the lubricating and cooling liquids used. The article describes the mechanism of processes occurring in the circle–blank contact, determined from the position of physicochemical mechanics of materials. Data on influence of rheological characteristics of “LPG + dispersion product” systems and physical and chemical properties of LPG on cutting properties of abrasive tool are presented. The behavior of this colloidal system by viscosity is described. Dependencies characterizing coagulation of metal particles between each other and with cutting profile of grinding wheel in “tool–workpiece” contact under conditions of turbulent flow of LPG and dispersion products are obtained.
