Application of minimum lubrication methodology for diamond spark grinding

Abstract

The electric discharge bases of the technological advantages of diamond spark grinding make it possible to consider this processing method among the environmentally promising in nature. A decrease in the thermo-mechanical tension of mass micro-cutting in the zone of diamond spark grinding, which is ensured by the development of its working relief, supported by the action of electric discharges on the bond of the wheel, also makes it possible to consider approaches to organizing this process using the minimum lubrication methodology. The paper presents and summarizes the experimental results of using a number of solid lubricants, gives practical recommendations and defines the tasks of further research. Work in this direction is focused on reducing the use of water in servicing industrial needs, which is an urgent global environmental challenge to the development of civilization and meets the modern technocratic strategies of the European Union (Industry 4.0), Japan (Society 5.0), China (Made in China 2025) and other leading world economies.
