PART SURFACE WORKING METHOD AND APPARATUS Russian patent published in 1996 - IPC

FIELD: mechanical engineering, in particular, elimination of casting, pressing, forging, hot and cold stamping defects. SUBSTANCE: method involves supplying charge of parts into treatment medium; mixing parts in treatment medium and moving while vibratory action upon the whole charge is provided; transmitting progressive motion in the direction transverse to current flow to portion of parts charge by subjecting it to the action of high-speed medium flow. Apparatus is formed as resiliently suspended working chamber with vibrator and ejector-type abrasive jet gun rigidly fixed relative to casing.
