FIELD: mechanical engineering.
SUBSTANCE: fastening ring, which has an outer base surface, is coaxially carried on the emery wheel with its working surface to be treated is mounted on the sample surface of the machine table, is used as an additional reference plane, and polished. The specific wear of the emery wheel is determined by dividing the volume of the spent abrasive on the amount of emery material. For this purpose, before and after grinding produce measuring the distance from the outer surface of the base ring to the base surface and an additional distance from the surface of the treated sample to the additional base plane. From the corresponding value difference of the mentioned distance of the radius of the emery wheel before and after grinding is determined.
EFFECT: reduced labour intensity and improved accuracy of determining the specific wear of the grinding wheel by avoiding direct contact measurement tools with the grinding wheel.
