Novel steel rail end face grinding superhard grinding wheel structure

The invention discloses a novel steel rail end face grinding superhard grinding wheel structure. The novel steel rail end face grinding superhard grinding wheel structure comprises a grinding layer and a base body, inner chip grooves and outer chip grooves which are distributed in a staggered mode are formed in the grinding layer, and the inner chip grooves and the outer chip grooves are semi-through grooves in the ring width direction of a grinding wheel. The grinding wheel structure is changed by additionally arranging the inner and outer chip grooves, so that continuous grinding heating isblocked in the grinding process of the grinding wheel, the chip removal and heat dissipation functions are enhanced, and the problems that a rail burns, and the service life and the strength cannot beconsidered simultaneously in the research and development process of the steel rail grinding superhard grinding wheel are solved. Compared with a grinding wheel without a chip groove, the chip removal and heat dissipation per
