Comparative Assessment of Wear Indicators in Grinding Discs During Grinding of Selected Steels

In the paper basic experimental tests were carried out to compare the wear indicators of selected abrasive grinding discs in grinding process of steel. Experimental tests on the wear and efficiency of metal grinding discs were made for four types of steel (S235, NC6, Hadfield steel, WNLV + QT steel). The wear parameter included in the ISO standard (KG) of new abrasive discs from European market were examined. This paper presents an analysis of the efficiency and wear of the company’s „MOST” grinding discs using an angle grinder.
