FIELD: process engineering.
SUBSTANCE: invention relates to finishing jobs and can be used for bright-finishing of complicated-shape parts. Parts to be machined and working medium are placed in tight drums. Said drums are arranged in containers fitted in bearings mounted on pinion frame. Planetary motion and variable angular speed are imparted to said drums that rotate relative to pinion frame. Invention comprises design relationships between angular speed variation and vibration acceleration.
EFFECT: higher stability and efficiency of machining, improved surface quality.
