接著，如圖11B所示，當該偏位傳動組70的齒輪機架71帶動該第一傳動件72A和該第二傳動件72B朝向圖11B的右側運動時，由於該第一傳動件72A之轉位齒輪721A與該第二傳動件72B之轉位齒輪721B皆為負轉位齒輪；因此該第一傳動件72A之轉位齒輪721A能在保持嚙合與不干涉的條件下，移向該輸入齒輪24；而該第二傳動件72B之轉位齒輪721B能在保持嚙合的條件下，遠離該輸入齒輪24。在圖11B中，該第一傳動件72A之轉位齒輪721A較該第二
傳動件72B之轉位齒輪721B靠近該輸入齒輪24、具有較大的工作深度，且該第一中心距D1小於該第二中心距D2。

最後，如圖11C所示，當該偏位傳動組70的齒輪機架71帶動該第一傳動件72A和該第二傳動件72B朝向圖11C的左側運動時，同樣地，因所述轉位齒輪721A、721B皆為負轉位齒輪；因此，在圖11B中，該第二傳動件72B之轉位齒輪721B較該第一傳動件72A之轉位齒輪721A靠近該輸入齒輪24、具有較大的工作深度，且該第一中心距D1大於該第二中心距D2。

如圖11B所示，左側的該轉位齒輪721A較右側的該轉位齒輪721B靠近該輸入軸20的輸入齒輪24且具有較大的工作深度，該第一中心距D1小於該第二中心距D2；接著，如圖11A所示，兩該轉位齒輪721A/B與該輸入齒輪24距離相等；最後，如圖11C所示，右側的該轉位齒輪721B較左側的該轉位齒輪721A靠近該輸入軸20的輸入齒輪24而具有較大的工作深度，該第一中心距D1大於該第二中心距D2。

在本創作中，該輸出軸80直接由該輸入軸20帶動而能高速旋轉；該徑向凸輪組60的凸輪61被該行星架51帶動而緩慢地旋轉，該凸輪61帶動該輸出滾子座62、該偏位傳動組70和該輸出軸80沿著徑向緩慢地往復運動，才能使該偏位傳動組70和該輸出軸80沿著徑向往復地進行低頻率的微小波動；如此一來，以本創作進行加工時便能些許地改變切削的狀態而中斷連續的帶狀切削屑，並且進而避免連續的帶狀切削屑所帶來的各種問題。

如圖10所示，該輸出軸80的軸心81C相對該軸體21的軸心21C的偏移量大於切削屑的厚度，使本創作能夠中斷連續的帶狀切削屑且適用於粗加工的場合。
