A method is offered for profile surface strengthening in blade part channels. This method integrates processes of vibration and extrusion processing. During processing the oscillations from a vibratory machine are passed to the part worked and located within a cylindrical container with granulated during processing work environment. Under the impact of low-frequency vibrations at the expense of periodic alternate container revolutions a reciprocal shift of strengthening granulated environment on inter-blade channels of the part takes place.

Technological problems arising at high-speed rotor balancing in turbine pump units are considered. There are shown their operation conditions of work in view of working surface softening against an extraneous technological heredity in the areas of metal removeall. The ways for the improvement of rotor technological development processes with the use of the methods of local finish-strengthening combined processing.

This work presents the research and development data in the field of finishing and hardening processes for parts with complicated shape surface. The comparable effectiveness of different surface finishing and hardening processes were studied, and intensification possibilities of processes of vibration finishing - hardening machining of narrow ducts by means of combined methods with metal anodic dissolution were shown. The results of experimental researches of influence of extrusion conditions of granular media on the surface layer quality are presented.

Is studied of the features of anodic dissolution in the process of local combined processing of metal removal points with surface defects arising during balancing of high-speed rotors in connection with the softening of working surfaces from unwanted technological heredity. The ways of improving the processes of their technological refinement using local hardening methods are shown, calculation formulas are given technological parameters of the anode process.
