Background. The introduction of high-performance technologies of centrifugal volumetric processing of parts at domestic industrial enterprises is constrained by limited opportunities for the acquisition of technological equipment and insufficient knowledge of centrifugal processing methods. The purpose of the work is to increase the efficiency of centrifugal finishing, strengthening and stripping processing of parts based on the creation of new schemes and technological support for their implementation in production conditions. Materials and methods. It is proposed to increase the efficiency of the process of volumetric surface treatment of parts by scientifically-based regulation of the speeds of planetary rotation of containers to control the movement of the working load in the volume of the container and reduce or periodically eliminate the stagnant zone based on the study of the dynamics of the process. Calculated dependences are proposed for determining the boundary of the transition from volumetric processing of parts in a sliding layer to the transformation of working bodies into a dense tool for polishing the wall, i.e. processing the inner annular surfaces of parts. Results. New technical solutions have been proposed to stabilize the quality indicators of the surfaces of parts and prevent defects during volumetric centrifugal processing, the effectiveness of which has been confirmed by experimental verification. To evaluate the performance of centrifugal processing, an empirical mathematical model of the metal removal process was obtained, which allows determining the amount of technological allowance removed under specified processing conditions. Conclusions. The introduction of new methods of finishing, strengthening and stripping processing will increase the efficiency of technological operations and refuse to purchase equipment for the mechanization of these operations abroad.
