Title:
SUPERCONDUCTING WIRE WIDTH MACHINING METHOD
Document Type and Number:
WIPO Patent Application WO/2007/123103
Kind Code:
A1
Abstract:
A method for machining a superconducting wire formed by using a broad-width substrate
without lowering the superconduction characteristics so as to make a slit in
the wire with a high production efficiency. The method comprises a step of preparing
a superconducting wire (S) and a machining step of cutting the superconducting
wire (S) by means of machining sections (31 to 35) including opposed two cutting
portions (21 to 30). The machining sections (31 to 35) include two or more pairs
so arranged as to be adjacent at intervals in the width direction of the superconducting
wire (S) in such a way that the superconducting wire (S) is sandwiched between
two cutting portions (21 to 30). The contact positions of the cutting portions
(23, 26, 27, 30) in contact with one surface (S2) of the superconducting wire (S)
are outside in the width direction of the superconducting wire (S) from the contact
positions of the cutting portions (24, 25, 28, 29) in contact with the other surface
(S1).
