PURPOSE:To lead media into the inner side of a work and a shaft into a guide as well as to aim at the equalization of finish roughness in both inner and outer surface of the work, by inserting an antislip regulating member for the work into both ends of a small diametral shaft which makes the ringlike work insertable at will. CONSTITUTION:When works 9 are polished with jigs 8 for barrel polishing use, on side of plates 11 is removed from a shaft body 10, then works 9 are inset in series and the plate 11 is reset so that these works are inset and set up on the shaft body 10. And, when jigs 8 are put in a barrel 3 and a motor 7 is started, a vibration to be produced by rotation in each of upper and lower balance weights 5 and 6 is transmitted to the barrel 3, making media 2 circulate inside the barrel, thus polishing takes place. Hereat, these media 2 positively circulate in through holes 9a and sufficiently enter the inner side of each work 9 whereby the innder surface of each work 9 is also sufficiently polishable like the outer surface. |
