Unbalances formation of the textured wheel at preparation to grinding process

Abstract

Abstract The entrance factors of grinding processes of materials, affecting dynamic activity of a technological system, define exit indicators of processes: operation productivity, geometrical and physic-mechanical indicators of quality of the processed blanket, etc. One of such dominating factors is unbalance of quickly rotating grinding wheel, which role continuously increases in connection with a current trend of increase of cutting speed. Formation of the main vector of unbalances of the textured grinding wheel during his preparation to work is analysed. The mathematical model of unbalances, caused by errors of production of abrasive cutting elements, their assembly with the metal case, installation of the tool on a spindle, and also by uneven removal of abrasive material in the course of its first editing, is developed. On the basis of the established mathematical model the numerical values of unbalances of the textured grinding tool are defined and the recommendations, providing values of the main vector of the imbalances, regulated by the standard, are developed. The results of researches are necessary for high-quality design of the textured grinding wheels, intended for grinding of responsible surfaces.
