ABRASIVE DISC IMPREGNATION

Abstract

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 materials, 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.
