本研究是運用電泳沉積輔助SiC磨粒對SUJ2軸承鋼進行表面拋光，並輔以電泳沉積改善拋光輪所能有效運用加工之磨粒數量，提高對SUJ2軸承鋼之拋光效率及達到更細緻的SUJ2軸承鋼加工表面粗糙度，以降低製程成本及減少加工時間。並於實驗中探討於各種加工參數如：工作電壓、加工時間、軸向負荷和拋光輪轉速對加工後表面粗糙度及表面形貌的影響，另實驗中進行了傳統機械拋光與電泳沉積輔助拋光對SUJ2軸承鋼拋光結果的比較。 經由實驗結果分析顯示，SUJ2軸承鋼工件於傳統機械拋光中，原始表面粗糙度可改善至Ra值0.028 μm，表面粗糙度Rt改善至0.296μm；加入電泳沉積輔助拋光後，工件原始表面粗糙度Ra可改善至0.023μm，表面粗糙度Rt改善至0.258μm，表面粗糙度Ra值優於一般傳統拋光17.86%，表面粗糙度Rt值優於一般傳統拋光12.84%，證實運用電泳沉積法輔助拋光，能使表面粗糙度改善效率更加明顯，且更能形成更好的表面形貌。 ;The study is focus on mechanical polishing and electrophoretic deposition polishing to improve the surface roughness of SUJ2 ball bearing steel. An approach to improve the efficiency of the polishing process by using electrophoretic deposition polishing. The experimental parameters includes voltage, machining time, polishing loading and polishing spindle speed. The roughness of SUJ2 surface and the morphology of SUJ2 surface were measured and evaluated. The result of experiment shows the original roughness of SUJ2 in traditional polishing of mechanism can be improved to Ra 0.028 μm and Rt 0.296 μm. After executing Electrophoretic Deposition polishing, the original roughness of SUJ2 can be improved to Ra 0.023 μm and Rt 0.258 μm. Electrophoretic deposition polishing was obviously superior to traditional polishing process. The roughness (Ra) of SUJ2 using electrophoretic deposition polishing was better than the roughness (Ra) of SUJ2 using traditional polishing by 17.86%. At the same time the roughness (Rt) was better by 12.84%. The result proved the electrophoretic deposition polishing can be more efficient to the surface polishing of SUJ2. Namely, it can promote the better surface texture of SUJ2.
