Abstract

PURPOSE:To polish the peripheral portion of a nozzle efficiently by preventing the weight of an abrasive member from applying directly to the polishing surface by means of a balancing mechanism and controlling the polishing pressure of the abrasive member at a constant value. CONSTITUTION:A rotary polisher 50 consisting of an abrasive member 12 and a drive mechanism 13 for rotating the member 12 is supported by a box 14 through an elastic member 16. A balancing weight 17 is connected to the polisher 50 through a rope 19 and a pulley 20 so as to prevent the weight of the member 12 from applying directly to the polishing surface. To ensure that the member 12 polishes at a predetermined polishing pressure, a position detector 21 detects the changes in the relative position of the polisher 50 as regards the box 14 and the polishing pressure is controlled at a predetermined value.
