In order to solve the problems of the effectiveness increase in parts machining with grinding there are developed impregnated abrasive discs. The impregnated grinding disc application allows increasing effectiveness, intensifying a process, increasing surface smoothness with minimum defects as compared with non-impregnated disc grinding. The investigations of grinding processes were based on the regulations of the theory of friction and wear, theory of cutting, physical-chemical mechanics of

... erials, physical and colloid chemistry, non-equilibrium thermodynamics. Physical-chemical processes accompanying grinding with impregnated grinding discs are investigated. It is defined that a cutting ability of a grinding disc and its durability increase, glazing decrease and quality improvement of a part worked take place. New methods for obtaining a composition for impregnation are tested. It is substantiated theoretically and confirmed experimentally grinding effectiveness increase at the introduction into an abrasive mass composition a film-forming matter – chromium diiodide.
