PURPOSE: To permit a various sorts of polishing by installing a turret so that barrel tanks are rotated and revolved, and arranging the whole of polishing machine in which the barrel tanks are rotatable around the shaft, onto a roller so as to be shiftable in the vertical and the horizontal directions.

CONSTITUTION: A pair of round rods 3 and 3a equipped with rollers 2 and 2a at the both edges are axially supported onto the both sides of a machine base 1, and a pair of rolling plates 8 and 8a are rotatably installed between the rollers 2 and 2a on the both sides. These rolling plates 8 and 8a are connected through the side plates 9 and 9a on one side, and a rolling frame is constituted, and a planetary-wheel driving wheel is rotatably installed onto a main shaft 18 axially mounted between the both side plates 9 and 9a, and a turret driving wheel 20 and a disc-shaped turret are fixed, keeping a prescribed distance. A plurality of barrel tanks are rotatably laid through a barrel shaft between the wheel 20 and the turret 21, and a driving wheel is fixed onto one barrel shaft.
