Process and apparatus for manufacturing an abrasive wire

摘要

A process for manufacturing an abrasive wire formed by abrasive particles held on a central core by a binder comprises depositing abrasive particles on the central core, each particle comprising a magnetic material that has a relative permeability greater than 50 and that represents at least 1% of the volume of the abrasive particle, and depositing binder on the central core to keep the abrasive particles attached to it. The core has south poles and north poles alternating along either its circumference or its length.

1. A process for manufacturing an abrasive wire formed by abrasive particles that are kept on a central core by a binder, said process comprising providing a central core, depositing magnetic abrasive particles on said central core, and depositing a binder on said central core, wherein said central core comprises a surface, wherein north poles and south poles are disposed on said surface, wherein said north poles and south poles are distributed in alternation along at least one of a circumference of said central core and a length of said central core, wherein, as a result of said distribution, a south pole is adjacent to two north poles, wherein, as a result of said distribution, a north pole is adjacent to two south poles, wherein each magnetic abrasive particle comprises a magnetic material, wherein said magnetic material has a relative permeability that is greater than 50, wherein said magnetic material represents at least 1% of a volume of said magnetic abrasive particle, wherein depositing said magnetic abrasive particles creates a magnetic interaction between said central core and said abrasive particles, wherein said magnetic interaction attracts said abrasive particles to said central core, and wherein depositing said binder on said central core results in keeping said abrasive particles attached to said central core.
