Abstract

Processes of cutting of steel details diamond and abrasive are investigated by circles. It is established that decrease in the cutting ability of diamond wheels with granules from polycrystals of synthetic diamond at metal working happens because of primary wear of granules, at the same time the speed of wear of granules exceeds the speed of wear of a sheaf. The wear of a granule comes from polycrystalline diamond on the specific mechanism which is implemented in the conditions of frictional interaction with a near-surface steel layer being in liquid, viscous and plastic states
