ON THE EXPEDIENCY OF APPLICATION OF GRINDING WHEELS WITH A BROKEN PROFILE IN OPERATIONS OF CENTER-FREE GRINDING OF ROTARY SURFACES

Abstract

The comparative analysis of the work of grinding wheels with a continuous and intermittent working surface for finishing abrasive treatment of the surfaces of roller bearing rings is made in the work. For the finishing abrasive treatment of the surfaces of the roller bearing rings, it is shown that the results of the expected contact temperature, roughness and wear intensity at a given intensity of metal removal are confirmed by theoretical calculations. The obtained results allow us to conclude that in centerless grinding operations, especially when machining roller bearing rings, it is advisable to use grinding wheels with an intermittent surface.
