Magnetic abrasive finishing process is one of the advanced finishing technique, which is commonly used to improve the surface accuracy and dimensional of many products in various application such as for medical implant, automotive, electrical, and IT, etc. In this study, the MAF process using rotating magnetic field with flexible processing force is used to smooth the surface of STS 316L stents wire under the optimal conditions such as rotating speed: 150, 350, 600rpm; diamond grain size: 1, 3, 6-μm, and processing time: 20, 40, 60, 80min. The results showed that under the processing conditions, quality enhancement in surface accuracy of STS 316L stent wire is achieved, in which the surface roughness is reduced from 0.22 to 0.06-μm.
