Fundamental researches on vibratory barrel finishing were conducted, and the following results were obtained.
(1) The vibration of the barrel wall was elliptical, which made the mass circulative. The moving velocity of the mass was larger with the increase of rotating velocity and charged load.
(2) The weight of removed metal was larger with the increase of rotating velocity, but not proportional to the moving velocity of abrasives; it was significantly affected by the dynamic force of abrasives.
(3) The grinding ability of the barrel was most effective in the bottom and less in the sliding zone.
The result was quite reverse to ordinary rotating barrels.
