Abstract:	本實驗方法之研究乃使用一螺桿，於高速旋轉下，來帶動流體介質使其快速流動，對於工件圓內孔表面進行研磨拋光。本實驗中，藉著控制螺桿轉速、加工時間、磨料濃度、磨料粒徑、磁束密度等參數，探討對於磨料溫度變化、內孔表面粗糙度及材料去除率等影響，並以田口方法找出最佳實驗參數；同時於實驗後觀察，各實驗參數對工件圓內孔表面是否有外觀上的影響。從實驗結果得知，磨料的良好流動性，有助於精細之螺旋研拋，使得工件可達到理想之圓內孔表面研拋成果。而選用細微磨粒配合最佳實驗參數條件下，可獲得更佳表面粗糙度，由原工件內孔表面粗糙度自0.478?mRa有效降至0.204?mRa。 The study is about the polishing of inner surface by abrasive, which is propelled by a spiral spindle. In this experiment, we discussed the effects upon working temperature, surface roughness, and material removal rate by controlling the speed of spindle rotation, machining time, abrasive concentration, particle size and magnetic density. Also, we could find the best experimental parameters by Taguchi Methods. We observed the influence of these parameters on the polished surface. The result of the experiment shows that the good mobility of abrasive is beneficial for fine spiral polishing to achieve a more ideal polishing effect. The best polishing effect can be obtained by using small-particle and high-concentration abrasive. The roughness of the surface can be effectively lowered from 0.478?mRa to 0.204?mRa
