METHOD OF PRODUCING FINE TUBE BY ELECTROFORMING, CORE WIRE, AND CORE REMOVAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a fine tube by electroforming where a core wire is removed from a casting obtained by applying electroforming to the core wire without deforming the fine tube and the production of a finer tube of higher precision is realized, to provide a core wire, and to provide a core removal device. SOLUTION: The fine tube is produced by: a stage where electroforming is applied to a core wire 901 to produce a casting 902; a stage where both ends of the core wire 901 are held by a movable chuck 903 so as to stretch the core wire 901, and the boundary between the casting 902 and the core wire 901 is peeled; and a stage where the core wire 901 is removed from the casting 902.
