PURPOSE:To eliminate the variation of the polishing force due to the addition of a new media to a mass, by inserting a new media into a mass in a barrel work container while containing in a easily fracturable pakage. CONSTITUTION:A new media 4 and a powder compound 5 are placed in a vinyl bag 3 to constitute a package 1. Then it is hooked by a resilient hook 7 through a string 6 and inserted into a mass fluidified in a barrel work container. The bottom of the vinyl bag 3 is fractured by the fluidified mass thereby the powder compound and a new media 4 are gradually mixed with the mass 2. In such a manner the variation of the polishing force due to the abrupt increase of the new media is prevented resulting in the stable polishing work. |
