This study proposes a new wire magnetic abrasive finishing (WMAF) process for finishing 316L SUS wire using ecological magnetic abrasive tools. 316L SUS wire is a biomaterial that is generally used in medical applications (e.g., coronary stent, orthodontics, and implantation). In medical applications of this material, a smooth surface is commonly required. Therefore, a new WMAF process using ecological magnetic abrasive tools was developed to improve the surface quality and physical properties of this biomaterial. In this study, the WMAF process of 316L SUS wire is separated into two finishing processes: (i) WMAF with ecological magnetic abrasive tools, and (ii) WMAF with industrial magnetic abrasive tools. The ecological magnetic abrasive tools consist of cuttlefish bone abrasives, olive oil, electrolytic iron powder, and diamond abrasive paste. The finishing characteristics of the two types of abrasive tools were also explored for different input parameters (i.e., vibrating magnetic field and rotating magnetic field). The results show that ecological magnetic abrasive tools can improve the initial surface roughness of 316L SUS wire from 0.23 µm to 0.06 µm. It can be concluded that ecological magnetic abrasive tools can replace industrial magnetic abrasive tools.
本研究提出了一种使用生态磁性磨具对316L不锈钢丝进行光整加工的新型磁力研磨工艺（WMAF）。316L不锈钢丝是一种生物材料，通常用于医疗应用（如冠状动脉支架、正畸和植入）。在这种材料的医疗应用中，通常需要光滑的表面。因此，开发了一种使用生态磁性磨具的新型WMAF工艺，以提高这种生物材料的表面质量和物理性能。在本研究中，316L不锈钢丝的WMAF工艺分为两个光整加工过程：（i）使用生态磁性磨具的WMAF，以及（ii）使用工业磁性磨具的WMAF。生态磁性磨具由乌贼骨磨料、橄榄油、电解铁粉和金刚石研磨膏组成。还针对不同的输入参数（即振动磁场和旋转磁场）探索了两种磨具的光整加工特性。结果表明，生态磁性磨具可将316L不锈钢丝的初始表面粗糙度从0.23μm提高到0.06μm。可以得出结论，生态磁性磨具可以替代工业磁性磨具。
