Abstract:
PURPOSE: To enable it to operate for hours even if a sliding-contact clearance is not preset so widely as well as to make a thin, small work polishable
CONSTITUTION: This is a dry barrel polishing device equipped with a dust collector 5 which inhales dust produced by a mass 2 toroidally flowing in a polishing barrel 1 from a sliding contact clearance 16 between a fixed barrel 3 and a turntable 4. Plural pieces of suction holes 8 are formed in this turntable 4. An interval between respective suction holes 8 and an inner part of the polishing barrel 1 is interconnected by a turntable clearance 15 which is formed after an auxiliary suction plate 9 is covered on each suction hole 8 so as to be opened to the mass 2 is toroidally flowing. The turntable clearance 15 and each suction hole 8 are set up in an auxiliary suction passage interconnecting an interval between the polishing barrel (1) inside and the dust collector 5.
