Marksa, Novosibirsk, 630073, Russian Federation Abstract In the manufacture of many parts, both machining and quenching are required. Such operations are usually performed at different sites. Increasing the production efficiency of such parts can be achieved by integrating additional operations into metal cutting equipment. The purpose of the work is to consider hardening methods for further integration into standard metal-cutting equipment. Theory. In the theoretical part, the features of each proposed method are considered. Results and discussion. The methods of surface hardening of the lead screw of non-standardized technological equipment of experimental synchrotron radiation stations are considered. The schemes of processing the profile of the running thread with different variants of surface hardening are presented. As a result of the analysis, the method of high-energy heating with high-frequency currents (HEH HFC) is chosen as the most rational. The results obtained will serve as the basis for further design of hybrid equipment.
