PROBLEM TO BE SOLVED: To surely remove burrs having different growth directions which are formed in a resin molding without damaging the molding. SOLUTION: In a production method, a driving means 264 is driven, and the high pressure pump 263B of a liquid supply means 263 is driven. A support member 261 including nozzles 262 is rotated around a vertical shaft 266, and high pressure water is ejected from the nozzles 262 from above toward the resin molding 21. By the rotation of the support member 261, the direction of the jet 40 of the high pressure water ejected from each nozzle 262 is changed diagonally downward to the vertical axis 41 of the support member 261. In other words, the jet 40 from each nozzle 262 is ejected in all the directions around the vertical axis 41 to the resin molding 21. COPYRIGHT: (C)2006,JPO&NCIPI |
