Title
(EN) PROCESS AND APPARATUS FOR MANUFACTURING A CUTTING WIRE
(FR) PROCEDE ET APPAREIL DE FABRICATION D'UN FIL DE DECOUPE
Abstract
(EN)
This process for manufacturing a cutting wire formed of abrasive particles held on a central core by a binder, comprises: a) the deposition (204) of abrasive particles on the central core, each abrasive particle comprising a magnetic material, the relative permeability of which is greater than 50, this magnetic material representing at least 1% of the volume of the abrasive particle, and b) the deposition (204, 208) of the binder on the central core in order to keep the abrasive particles attached to this central core. During step a), a magnetic interaction is created (202, 206) between the central core and the magnetized abrasive particles in order to attract the magnetized particles to the central core and, before step a), the central core has, at its surface, at least two south poles and two north poles distributed alternatively along its periphery and/or along its length.
