Marksa, Novosibirsk, 630073, Russian Federation Abstract Purpose: The required operating features of machine parts are mainly formed at the final stage of its production process. In this regard, the objective is to investigate the features ensuring the quality characteristics of the surface layer of products, achieved at the last step of the integrated processing - diamond smoothing. Methods: The experi- ments were performed on a lathe equipped with an additional source of energy, in the function of which the external quenching circuit providing high-energy high-frequency heating was used. Structural studies were carried out with appliance of optical and scanning electron microscopy. Stress-strain state of the surface layer part was evaluated by X-ray and mechanical methods for the determination of residual stresses. The surface roughness assessment was implemented on the profilograph-profilometers Form Talysurf Series 2 and Zygo New View 7300. Results and Dis- cussion: It is found that the diamond smoothing of samples of steel 45 under the proposed principle of integration, which allows processing of parts from one technological base, makes it possible to increase the surface microhard- ness and residual stress level of compression achieved during the transition surface hardening by high frequency.
