The results of studies of the type influence of treatment and tool material on the structural state of the boundary layer 107WCR5 during treatment are shown. The advantages of turning chisels with composite 10 compared with the process of grinding. Processing treatment with composite 10 in the surface layer for α-and γ-phase is accompanied by compressive residual stresses only, while the abrasive treatment is accompanied by tensile stresses in the kind of I-α- phase structure of high-speed dispensing.
