Study of Magnetic Finishing for an Internal Surface Using a Permanent Magnetic Pole

Abstract

Magnetic finishing is a new machining technology. It was widely developed for its high productivity and quality, especially its better flexibility and self-sharpness finishing tools. As a new material, Nd-Fe-B with high magnetic energy makes the internal finishing easier. Being used as permanent magnetic pole to finishing the surface of workpieces instead of solenoid, it makes the structure of magnetic pole more compact and the techniques adaptability better. Internal finishing using permanent magnetic pole is…
