Description
Summary:A novel magnetic abrasive finishing (MAF) technique employing a rotating magnetic disc is developed to address the issue of uneven polishing on large-sized slender tubes. The method involves arranging a series of magnetic poles in an S–N-S–N configuration on a pair of rotating discs, with the tubes being processed fed between the gap of the two discs. This approach results in a 246% increase in finishing efficiency compared to traditional MAF processes, where only the workpiece rotates. The finishing characteristics are determined by the interaction of the magnetic abrasive particles (MAPs) with the tube’s outer surface. This interaction is regulated by the magnetic field distribution on the surface and the contact trajectory density of the MAPs. The S–N-S–N magnetic pole configuration defines the magnetic field characteristics, which in turn control the magnetic force and the contact trajectory required for the MAPs behavior. An experimental design method was employed to determine the optimal process for a 5-m-long zirconium alloy cladding tube, utilizing a high-speed feeding rate of 5 m/min. Even at high feed rates, the tube’s surface can be processed with dense trajectories and consistent results. The outer surface roughness of the zirconium alloy cladding tube was reduced by 31%, from 0.356 to 0.247 µm, after a single-pass treatment. Following MAF processing, the final roughness can reach 0.126 µm.
