Influence of various types of spherocorundum on the performance of grinding wheels

The effect of introducing filled spherocorundum and hollow spherocorundum into the composition of grinding wheels on epoxy resin on the grinding coefficient, cutting ability, constituent cutting forces, temperature and quality of treated surfaces during implementation of a flat grinding operation is investigated. It has been established that replacing 40% of abrasive grains of electrocorundum in grinding wheels with filled spherocorundum with the same chemical composition and grain size reduces tool wear by 42%. It was also found that replacing 40% of abrasive grains with a hollow spherocorundum of similar grain size leads to a decrease in heat generation during grinding by 25%, as well as a significant reduction in deformations of the processed material during processing, compared with grinding wheels without adding spherocorundum.
