Abstract

Method for manufacturing cutting wheels, according to which method abrasive grains are combined with a resin and curing to bond the grains with an infusible resin bonding agent, characterized in that it is used as at least 25 percent by weight of the abrasive content, an alumina-zirconia abrasive, which is formed by fusion and has a zirconia content of between 10 and 60 weight percent, an average primary alpha-alumina crystal diameter less than 40 microns and a elongated in such a way that its density in volume on the grain size scale 24, is within the scale of 1.8 times, specific gravity 4.35 to 2.2 times of specific gravity 4.35 grams per cubic centimeter, where ge is the specific gravity of the abrasive grain material.
