ることになっていた。However, when a conventional polishing tool is used, the polishing time of the polishing leather and the buff is low, so that the polishing time becomes long and the inner hole surface becomes close to a mirror surface. However, there is a problem that the leather and the buff for polishing and the adhesive used for coating them on the drill are melted by the temperature due to the heat generation.
Furthermore, in the inner hole of a tubular object, polishing by repeatedly reciprocating a drill coated with polishing leather or a buff over a long period of time can be performed by polishing the polishing leather or buff tissue with an abrasive or a tubular material. Were to be caught, giving him many opportunities to scratch the inner surface of the bore.

に設定しなければならない。When the polishing tool of the present invention is used, first, the polishing tool is inserted from one end of the inner hole of the tubular article to the other end, and the polishing head shaft is mounted so as to be located near one end of the tubular article. As a matter of course, the tool spindle used should be longer than the tubular object, and the outer diameter should be set smaller than the inner hole diameter of the tubular object.

ある。At this time, an external force is applied in the direction from the large diameter side to the small diameter side of the taper portion of the polishing head shaft to insert the polishing tool placed on the surface of the taper portion when the tubular article is inserted into the inner hole. Due to the action of the mechanism capable of press-contacting the inner hole surface of the tubular object, the polishing tool is pressed against the inner wall of the tubular object while rotating, which enables efficient polishing.
