Abstract
Compared to traditional polishing processes, the magnetic grinding method allows relatively easy polishing of the inner surface of tube fittings. For more than 7 mm thickness SUS304 tubes, the magnetic abrasive grains are subject to a small magnetic force and grinding pressure, leading to the low polishing efficiency. Therefore, a new magnetic grinding and polishing method is proposed, in which the grooved V-shaped magnet is conductive to spontaneous mixing and stirring with magnetic abrasive grains, allowing them continually being replaced for inner surfaces polishing on the tube. This can increase the grinding pressure of abrasive grains to the inner surface and contribute to high-quality surface polishing. Theoretically, it was proved that the grooved V-shaped magnet-assisted polishing tool improves the uniformity of material cutting force in the polishing process. Finally, this method was validated by the experiment with the 7 mm thickness SUS304 tube.
