Diffusion Phenomena in the Combined Electric Diamond Grinding

Abstract:

The problems of practical application of the combined electric diamond grinding (CEDG) are examined. Experiments were conducted on the grinding tool materials with metal-bonded diamond grinding wheels. In the presented part of the work, the roughness of the machined surface of specimens made of high-speed steel is investigated. It was established that the CEDG makes it possible to decrease the roughness of the machined surface to 30-40 % in comparison with other combined methods and 1.5-2 times in comparison with usual grinding. The application ensures the grinding by diamond wheels in the mode of self-sharpening and guarantees the continuity of its geometric form, which eliminates the defect layer on the machined surface and gives a longer period of wheel stability. The results obtained show that diamond wheels can be successfully used for grinding wide spectrum of tool materials.
