不鏽鋼的使用範圍越來越廣泛，從日常生活用品到高精度零件和醫療器材工具都包括在內，而這些不鏽鋼製品對於表面粗糙度以及耐腐蝕易清潔要求程度日益漸增，而傳統的不鏽鋼拋光及表面處理會受到工件外型難以加工或表面電解產生環境汙染。本研究使用磁力研磨拋光技術並使用自製磁性膠體磨料用於對鹽浴氮化處理過的#304不鏽鋼進行拋光研究。並以自行設計可在CNC數控銑床上使用之研磨刀具，並使用自製導磁性高分子膠體磨料結合於附有強力磁鐵的刀具上，利用磁力加以拘束自製之導磁性膠體磨料，用以對實驗工件表面進行研磨拋光加工，達到降低表面粗糙度以及改變材料表面親疏水性質的效果。
研究使用單因子實驗法來確認各個參數對於實際加工效果的影響，以不同磨料粒徑、鋼砂比例、磨料比例、進給率、主軸轉速探討其對加工效能之優劣影響，並利用田口式實驗法找出最佳化參數並且計算出各個因子貢獻度及重要性，使用最佳化參數進行對預測值進行驗證實驗，再量測加工前後試片表面對於親疏水性質的變化，而使用最佳化參數加工的試片表面由初始表面粗糙度Ra0.2936μm下降至Ra0.0136μm，表面粗糙度改善率為95%，試片表面也從原本親水性質的水滴接觸角69.3°改變至疏水性質的105.27°。

The finishing of #304 stainless steel in the market is mostly by electropolished to get smoothy and shine surface. However, these finishing methods must undergo longer time and environmental pollution. Magnetic abrasive finishing is a fast and high precision approach, but the magnetism of magnetic abrasive is reduced when finishing #304 stainless steel, and because the centrifugal force generated tends to throw abrasive away from the processing area, the efficency of finishing is thus decreased.
This study mainly focuses on the effect of the magnetic gel abrasives at stainless steel surface, and experiment the finishing efficiency of single factor. We used high polymer material gels as binders and restrained magnetic and hard abrasive grains in the gels to form magnetic gel abrasives. Since the gel abrasives are viscous, they can not only wrap around the abrasive grains to prevent from spreading, but also attach tightly onto the surface of stainless surface. We placed the magnetic gel abrasives on stainless steel surface to conduct finishing, and experiments using the Taguchi method and L18 orthogonal array are performed based on different abrasives rata to investigate the changes in surface roughness and material removal rate…The results showed that after 35min of stainless steel finishing choose right abrasive rata and steel grit, the surface roughness can be decreased from Ra0.2936μm to Ra0.0136μm, and the roughness improvement rate of this process would reach 95% and resistance repellency can be improved with surface smoothing. This proves that the magnetic gel abrasive finishing developed in this study has outstanding finishing effect on stainless steel.
