MAGNETIC ABRASIVE GRAIN, ITS MANUFACTURING METHOD, AND MAGNETIC GRINDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a magnetic abrasive grain for a more precise surface treatment, and to provide a method for manufacturing the same.;SOLUTION: The magnetic abrasive grain 1 is flat, and has an aspect ratio of ≥1.5. Preferably, the magnetic abrasive grain 1 is formed of nickel or a nickel-based metal such as a nickel alloy or formed of cobalt or a cobalt-based metal such as a cobalt alloy. Also preferably, the magnetic abrasive grain 1 is formed by cutting, pulverizing, or forging a magnetic thin film.;COPYRIGHT: (C)2006,JPO&NCIPI
