本研究以複合螺旋研拋機制，針對金屬射出成型之316L不鏽鋼進行表面研磨拋光實驗，以獲得表面精度及潔淨之品質。首先搭配田口實驗方法，對不同可控制因子進行分析，針對不鏽鋼表面粗糙度，找出最具影響的因子組合。綜合實驗結果配置出最佳的參數組合，分別為碳化矽粒徑300μm、磨料濃度60%、研磨轉速1200rpm與研磨時間120分鐘，並實際進行參數驗證。最後，就最佳化加工參數組合的實驗結果，對其表面形貌、表面粗糙度及材料去除率進行探討，得到最佳表面粗糙度Ra 0.32μm，其平均材料去除率為3mg/min，經由實驗結果顯示，本研究所採用的加工機制確薴有效提高表面光度，以達到表面研磨的效果。

This study was used composite spiral mechanism of polishing on 316L stainless steel surface polishing experiments to got high surface accuracy and cleansing after the metal injection molding. First, using of composite spiral polishing mechanism with Taguchi method, it's can be analyzes different controlled factors of stainless steel surface roughness, and then found out the most influential combinations of factor. Comprehensive all of the experimental results, we can get the best combination of parameters SiC grain size of 300μm, concentrations of abrasive is 60%, grinding speed of 1200rpm, and time of 120 minutes to use this constituencies to verification the experiment. Finally, follow the optimization experimental of results on surface morphology, surface roughness and material removal rate, we got the best surface roughness was 0.32μm Ra, and the average of material removal rate was 3mg/min. Finally, this polishing system could effectively improved the surface finish in order to achieved the effect of surface grinding.
