<p>PROBLEM TO BE SOLVED: To provide a pore polishing method capable of efficiently polishing the inner peripherys of pores in articles having through-holes consisting or large-diameter portions and small-diameter portions to be polished, in particular, optical connector phenols or capillaries, with high dimensional precision without causing hole openings to be rounded at the tips of the polished small-diameter portions. SOLUTION: In polishing articles 1 having through-holes 2 consisting of large-diameter portions 3 and small-diameter portions 4 to be polished, polishing wires 5 are inserted in the through-holes in the articles for lapping in the state that the plurality of articles are inserted and held in cylindrical guide bodies 6 with their large-diameter portions located at both ends to be directed to the outside. The guide bodies 6 can be guide caps having through-holes consisting of large-diameter portions 3 to fit the side ends of the small-diameter portions of articles to be polished therein and small-diameter portions 4 having minor diameters somewhat larger than or equal to those of the small-diameter portions 4 or guide bodies 6 for use in the state of being butted to the side ends of the small-diameter portions 4 of the articles 1.</p> |
