This study investigates the enhancement of surface precision and dimensional accuracy in STS 316L oval pipes through the application of magnetic abrasive finishing. The experiment involves the modification magnetic pole shapes(A, B, C, D) and a comprehensive analysis of their impact on surface quality. Key parameters include magnetic abrasive KX#320, iron powder, aluminum oxide, light oil, a test specimen rotating at 600rpm, and periodic injection of polishing liquid, a permanent magnet Nd-Fe-B, and magnetic pole steel 1018, reciprocating distance 20mm, and a feed rate 1mm/sec over a 32minutes duration with measurements every 4minutes. The results demonstrate significant variations in surface quality based on magnetic pole shape, with specific configurations demonstrating superior precision and smoothness from the initial surface 0.32μm to 0.06μm.
