WIRE DRAWING DIE FOR EXTRA FINE WIRE, AND METHOD FOR MACHINING AND REPAIRING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a wire drawing die in which no breakage occurs in manufacturing an extra fine wire, the diameter of the die is 5-50 μm and the dimensional accuracy is about ±0.1 μm, and to provide a method for machining and repairing the wire drawing die in which the die diameter or the like of the wire drawing die can be machined with the dimensional accuracy by using an FIB (focused ion beam).;SOLUTION: In the wire drawing die for an extra fine wire, the dimensional accuracy for the die diameter is 5-50 μm with the dimensional accuracy of ±0.1 μm by projecting condensed ion beams on a bearing part of the wire drawing die.;COPYRIGHT: (C)2005,JPO&NCIPI
