Projections are provided with slots dividing them into two parts. In addition, they have recesses for abrasive members. Recess on one part of projection is made from right-hand end of wheel and on other part, from left-hand end of wheel. Recesses provide for overlapping of abrasive members along wheel width by at least 1 mm. Method of wheel manufacture consists in attachment of abrasive members by their internal and side surfaces on ring.
