<P>PROBLEM TO BE SOLVED: To provide a serially connected nozzle polishing device that causes one of serially connected twin-fruid nozzles generating negative pressure to suck a polishing powder or a fluid and causes the other one to suck a cleaning material such as water, for spraying and polishing operation. <P>SOLUTION: The serially connected nozzle polishing device includes three serially connected nozzles comprising a first nozzle 1, a second nozzle 2 and a third nozzle 3 directly connected in series. To a first through tube 8 of the first nozzle 1 of the three continuously connected nozzles, a water tank 48 for supplying water is connected through a water supply pipe 49 and a regulating valve 56. To a through tube 23 of the second nozzle 2, a sand tank 50 for supplying sand is connected through a sand supply pipe 51 and the regulating valve 56. To a through tube 37 of the third nozzle 3, an iron powder tank 52 for supplying iron powder is connected through an iron powder supply pipe 53 and the regulating valve 56. The water, the sand and the iron powder are respectively supplied by using gravity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
