Abstract
A new technology of magnetic abrasive finishing (MAF) by applying rotating magnetic field generated pulse circuit was presented. The finishing mechanism was investigated, and the generation device of rotating magnetic field was designed and analyzed to finish the inner surface of non-ferromagnetic tube. The experimental results show: (1) The quality of the finishing is related to the magnetic pole structure: the NSSN structure brings out the highest quality, while the NSNS structure brings out the lowest quality. (2) The supplied weight of magnetic abrasive affects directly on the stock removal and the surface roughness, and it has an optimum value. (3) The finishing efficiency and the surface roughness can be improved effectively when magnetic abrasives are mixed with reasonable mesh-size iron powders in rational weight percent. The technology provides a good basis to spread the application in practical manufacturing.
