FIELD: technological processes.
SUBSTANCE: invention relates to polishing a machine part comprising at least one aerodynamic surface consisting of a low pressure side, an elevated pressure side, an edge guide and a trailing edge. Machine part is placed in container, polishing mixture is added into container and container vibrations are performed thus creating polishing mixture flow along aerodynamic surface. Frequency of vibration of container and machine part is selected with providing of polishing action on aerodynamic surface by means of abrasive powder.
EFFECT: as a result, aerodynamic surface roughness is reduced.
