Experimental investigation on the abrasive wear of AISI 52100 steel

Abstract

AISI 52100 steel has been widely used in various types of bearings in machinery equipment due to its excellent mechanical properties and high availability. In the final manufacturing process of bearing parts usually involve lapping and polishing methods on the ultra-precision machining in order to achieve high accuracy of profile and fine surface quality. The essence of this process is abrasive wear of AISI 52100 steel material. Therefore, in order to improve the super finishing process of bearings super finishing, the experiment of abrasive wear of AISI 52100 steel materials were carried out in this paper. The effects of different abrasive diameter and pressure on the material removal amount of AISI 52100 steel were investigated; the abrasive correction coefficient K in Preston formula was computed and obtained. The result shows that reducing the abrasive diameter can increase the material removal rate and improve surface quality when other factors are maintained constant.
