Study on Depth and its Uniformity of 65Mn Steel Grind-Hardened Layer
Abstract:
On the basis of orthogonal experiment method, the grind-hardening of 65Mn steel had been carried out on a conventional surface grinder with alumina grinding wheel, the influence of depth of cut ap, table speed vw, grinding mode gm, and interaction between depth of cut and table speed av on depth and its uniformity of grind-hardened layer of 65Mn steel were investigated. The results show that, the ap is the significant factor influences the average depth of grind-hardened layer and the significance ratio of experiment factors from most to least as followed: ap > vw > gm > av; the gm and the vw are the significant factors influence the depth uniformity of grind-hardened layer and the significance ratio of experiment factors from most to least as followed: gm > vw > ap > av. The fairly uniformity of grind-hardened layer with good economy can be obtained when using grinding conditions that the ap = 0.6mm, the vw = 0.4m/min, and the gm =up grinding + down grinding in practical applications.
