Article Preview

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 mainly discussed in this paper: a new technology to finishing the middle/small or deep hole using permanent magnetic pole is provided; a new kind of pole is developed, lots of experiments have been completed ,the roughness of internal surface is decreased from Ra0.8μm to about Ra0.3~0.1μm. The data prove that internal finishing using permanent magnetic pole is ideal technology.
