In this paper, we propose a new ultra-high-precision magnetic abrasive finishing method for wire material which is considered to be difficult with the existing finishing process. The processing method uses a rotating magnetic field system with unbonded magnetic abrasive type. It is believed that this process can efficiently perform the ultra-high-precision finishing for producing a smooth surface finish and removing a diameter of wire material. For such a processing improvement, the following parameters are considered; rotational speed of rotating magnetic field, vibration frequency of wire material, and unbonded magnetic abrasive grain size. In order to evaluate the performance of the new finishing process for the wire material, the American Iron and Steel Institute (AISI) 1085 steel wire was used as the wire workpiece. The experimental results showed that the original surface roughness of AISI 1085 steel wire was enhanced from 0.25 µm to 0.02 µm for 60 s at 800 rpm of rotational speed. Also, the performance of the removed diameter was excellent. As the result, a new ultra-high-precision magnetic abrasive finishing using a rotating magnetic field with unbonded magnetic abrasive type could be successfully adopted for improving the surface roughness and removing the diameter of AISI 1085 steel wire material.
在本文中，我们针对现有加工工艺难以处理的线材，提出了一种全新的超高精度磁性研磨加工方法。该加工方法采用无粘结磁性磨料型旋转磁场系统。据信，此工艺能够高效地进行超高精度加工，以获得光滑的表面光洁度并减小线材直径。为实现这种加工改进，考虑了以下参数：旋转磁场的转速、线材的振动频率以及无粘结磁性磨料粒度。为评估该新型线材加工工艺的性能，选用了美国钢铁协会（AISI）1085钢丝作为线材工件。实验结果表明，在转速为800转/分钟的情况下，AISI 1085钢丝的原始表面粗糙度在60秒内从0.25微米提高到了0.02微米。此外，去除直径的性能也很出色。结果表明，采用无粘结磁性磨料型旋转磁场的新型超高精度磁性研磨加工能够成功用于改善AISI 1085钢丝材料的表面粗糙度并减小其直径。
