Hrdbearing

According to the conformation medium of the grinding skin on the face of the Fag Bearing , there are two main factors that have a great effect on the grinding skin, videlicet grinding heat and grinding force. Because of the limited knowledge of the author, now in the following passages it'll bandy why the Grubber bearing loses the effectiveness from the perspective of grinding force.    How does the grinding heat do? During the grinding process, because of the touch of grinding wheel and work- piece, the Grubber bearing brings about a great number of energy and grinding heat. Therefore the part of the grinding area suddenly produces the high temperature. The instant high temperature results in the oxidization of the working face and other changes similar as unformed composition, high tempering, secondary quenching, cracking, burn and so on. For the failure of the Grubber bearing, the face oxide subcaste, unformed towel subcaste and high- temper subcaste are the fairly main rea...
