In this study, a magnetic pole vibration device that uses a proximity sensor for magnetic abrasive finishing equipment using apermanent magnet was developed, and the performance of this system was proved, focusing on how the surface roughness of STS304 pipes is affected by the magnetic pole arrangement. The results of this study confirm that the resulting magnetic fields of differentmagnetic pole arrangements change the behavior of the magnetic abrasive mixture, thus impacting the abrasion effect. Among thefour different pole arrangements investigated, the M-S-N magnetic pole arrangement provides the best surface finish. A mixture ofiron particles and magnetic abrasive materials in a 3 to 1 ratio is found to be the most advantageous in terms of surface roughnessand material removal rate. In addition, the wet processing, in which light oil is added to the magnetic abrasion mixture, is moreeffective than the dry processing. Finally, the effect of the spindle speed was also investigated for speeds from 200 to 1,400 rpm. At1,400 rpm, the surface roughness shows approximately 76.1% improvement over that at 200 rpm.
