Study on the polishing characteristics of the magnetic abrasives finishing to the slender pipe

Polishing the inner surface of slender pipe is very difficult. Because a usual tool cannot into the inner surface of the slender pipe, and automation do not achieved easily; the eye is unable to see, even if handmade is also very difficult. Utilize the characteristic of the magnetic force line may penetrate the non-magnetic material, may using the magnetic abrasive finishing (MAF) method complete to the inner surface of the slender pipe precise polishing is a preferable method and already obtained the good processing effect through the experiment. Therefore, this paper analysis and explanation the finishing principle and experiment device as well as collocation position of magnetic poles etc best experimental condition.
