PURPOSE:To make it possible to round the cut ends of high-hardness wires at a small radius of curvature in a short time, by charging a plurality of the high-hardness wires densely in a hollow protector, then by cutting the hollow protector by a predetermined length, and by polishing the cut surfaces of the wires. CONSTITUTION:A plurality of high-hardness wires 1 are charged in an aluminum hollow protector 2 by means of a vibrator. The hollow protector 2 having been charged with the plurality of high-hardness wires is pressed by a press unit 5 composed of a plunger 3 and a holder 4 so that the cross-sectioned shape thereof is deformed. Thereby, the wires 1 may be densely and firmly secured in a pipe 2 which is then cut into cut pieces having a predetermined length. Each cut piece is polished by emery papers in three grades. Since the wires are densely charged in the hollow pipe and are firmly secured, it is possible to satisfactorily round the cut ends of wires in a large amount within a short time.
