The objectives of the study are: 1) creation of conditions for automatic self-balancing and minimal vibration activity of the rotor in transient and operating modes of the rotary machine; 2) improvement of the process of plasma-mechanical processing of parts by creating and implementing an innovative complex of tooling and technological equipment; 3) development of scientifically grounded recommendations for technological preparation of the repair production of the mining and metallurgical complex. A new sliding bearing design with a variable geometry support surface has been developed, allowing the load vector to be brought closer to the vertical axis. The implementation of this technology can increase the service life of the support system by 30-60%. A sliding bearing assembly with a pressure regulation mechanism in the contact zone has been developed. The use of hydroplastic materials in the bearing structure has been proposed to ensure uniform load distribution. The developed plasma-mechanical processing method will lead to a 25–30% increase in the productivity of machining workpieces made of hard-to-machine alloys, enhancing manufacturing efficiency by reducing specific processing costs for machine parts in the energy and mining machinery industries. The development of scientifically substantiated recommendations for the technological preparation of repair production in the mining and metallurgical complex will ensure a 25–35% increase in the service life of friction surfaces. This will be achieved through the selection, justification, and implementation of methods for diagnosing and preventing the development of localized surface defects, thereby improving quality and overall production efficiency.
