<p>A resinoid grinding wheel comprising a dispersion of 25 parts by volume of Al2O3-base abrasive grains with grain size #150, 20 parts by volume of an organic hollow body with a mean grain diameter of 80 νm and 10 parts by volume of pores with a diameter of 1 mm in 40 parts by volume of an epoxy cured resin binder. This grinding wheel is reduced in grinding force and prevented from causing grinding burn without detriment to the characteristics inherent in resinoid wheels, such as low modulus of elasticity and good gripping strength of grain.</p> |
