Title:
HETEROGENEOUS METAL WIRE FOR USE IN MULTI-WIRE CUTTING, MANUFACTURING METHOD FOR SAME, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/106609
Kind Code:
A1
Abstract:
A heterogeneous metal wire (1) for use in multi-wire cutting, comprising two or more sets of heterogeneous parts. Each heterogeneous part consists of a curled part (12) and a twisted part (11). The axes of metal wires in the curled part are on a same plane. The axes of metal wires in the twisted part do not share any plane. The axes of the metal wires of the curled parts of a same set of heterogeneous part are within a same plane. The diameter of an outer envelope is 1.05-1.65 times of the average diameter of the metal wire itself. Also related are an apparatus and method for manufacturing the heterogeneous metal wire for use in multi-wire cutting. The heterogeneous metal wire is provided with a solid multidimensional structure, thus further improving cutting performance at an equal kerf loss; the structural retention capability of the heterogeneous metal wire is also further enhanced, thus facilitating reduced risks of cutting yield fluctuations.
