PROBLEM TO BE SOLVED: To provide a non-magnetic pipe internal surface polishing device suitably usable even when the internal surface of a non-magnetic pipe is severely fouled, preventing the efficiency of polishing operation from being lowered even when the polishing operation is performed continuously over a long period, and easily adjusting the intensity of a magnetic field according to the type of the non-magnetic pipe. SOLUTION: In this polishing device 1, a fixing means 3 for fixing the non-magnetic pipe P and a rotating magnetic field generation means 4 for generating a magnetic field rotated from the outside of the non-magnetic pipe P in the outer peripheral direction are installed on the upper surface of a horizontally long rectangular support base 2. A sucking means 8 for sucking the inside of the non-magnetic pipe P for removing polishing waste produced by polishing is installed in the rear of the rotating magnetic field generation means 4. A cooling means 9 for cooling the rotating magnetic field generation means 4 is installed on the side of the rotating magnetic field generation means 4. Polishing means 10, 10, ..., comprising long cylindrical magnet substances are contained inside the fixed non-magnetic pipe P. COPYRIGHT: (C)2010,JPO&INPIT |
