ОБРАБОТКА МЕТАЛЛОВ № 3 (68) 2015 73 ОБОРУДОВАНИЕ. инструменты The paper provides the results of comprehensive studies of the cutting power of electrocorundum wheels with ceramic bond impregnated with different compounds compared with non-impregnated wheels. The influence of impregnators on core parameters of the grinding process such as resistance and wear of an abrasive tool, energy consumption and roughness of a ground surface are studied. The studies revealed that when grinding the microporous coatings under given conditions the electrocorundum impregnated wheels have higher cutting power as compared with non-impregnated wheels. Comprehensive analysis of the studies based on a rating method revealed that when using the flat grinding method for the nickel- and iron-based microporous coatings the highest cutting power is attributed to wheels impregnated by triethanolamine and oleic acid impregnators. Keywords: microporous coatings, abrasive tool, grinding, impregnation, wheel resistance, cutting power, impregnator. DOI: 10.17212/1994-6309-2015-3-66-74 References 1.
