Claims

[Scope of Claim for Utility Model Registration] (1) A state in which a plurality of drums are installed at a fixed distance around a rotating shaft, and the drums are kept in a fixed direction with the rotating shaft as the center without rotating. 1. A centrifugal barrel polishing machine which revolves in a centrifugal barrel polishing machine, characterized in that the centrifugal barrel polishing machine is equipped with a forward/reverse conversion device capable of rotating the direction of rotation of the drum in the forward and reverse directions at regular intervals. (2) In a centrifugal barrel polishing machine in which a plurality of drums are mounted at a fixed distance around a rotating shaft and the drums revolve around the rotating shaft, the drums are moved in steps at a predetermined angle every fixed revolution. A centrifugal barrel polishing machine characterized by rotating the drum to change the direction of the drum. (3) The centrifugal barrel polishing machine according to claim 2, wherein the rotation of the drum is performed continuously at a very low speed instead of stepwise rotation. (4) In the above-mentioned drums of a centrifugal barrel polishing machine in which a plurality of drums are mounted at a fixed distance around a rotating shaft and revolve around the rotating shaft, the horizontal dimension of the drum cross section is compared with the vertical dimension. The drum should be at least 20% to 30% larger, with lids that can be opened perpendicularly on both sides of the drum's cross section, and a holder that fixes the polishing parts symmetrically with respect to the neutral axis of the drum's cross section. 1. A drum device for a centrifugal barrel polishing machine, characterized in that frames are attached to both sides, and the holding frames are attached in a manner that they can be separated from the drum body. (5) The drum device for a centrifugal barrel polishing machine according to claim 4, wherein the holding frame is attached to both sides of the drum body via a lid. (6) The drum device for a centrifugal barrel polishing machine according to claim 4, wherein the holding frame is fixed to the inner surface of a lid and is integrated with the lid.
