PURPOSE:To improve efficiency of working by mounting a plurality of work holding arms radially on a horizontal rotary shaft. CONSTITUTION:While a plurality of work holding arms are radially mounted on a horizontal rotary shaft 10, the respective work holding arms 11a-11h are provided on the ends with work attaching portions 12a-12h. By rotating these work holding arms 11a-11h together with the horizontal rotary shaft 10 are passed works W mounted on the work attaching portions 12a-12h through a media 21 in a barrel tank 1 being rotatably driven. Thus, when some works mounted on some work holding arms are inserted in the barrel tank 1, the other works mounted on the other arms protrude above the barrel tank 1 so that frinding and removable mounting of works can be carried out in parallel to improve the efficiency of working. |
