用单刃和多刃镗铰刀进行内孔的精密加工,是目前较广泛受到重视的一项加工工艺。为解决我厂生产的实际问题,我们使用以下两种结构的单刃和多刃镗铰刀,来加工鼓风机叶轮轴孔和联轴器销孔,效果很好.一、单刃镗铰刀图1为单刃镗铰刀的结构图,其特点是:(1)在切削刃后方90°和180°位置上有两条导向支承块,切削刃和支承块的外径座落在同一圆周上.切削刃刀片和支承块的材料均为 YG6.(2)刀片切削刃被分割成内、外、斜刃三部分,刀
With single-edged and multi-edge boring reamers for precision machining of the bore, is currently a more widely regarded as a processing technology. To solve the practical problems of our factory production, we use the following two types of single-edged and multi-edge boring reamers to process blower impeller shaft hole and coupling pin hole, the effect is very good. 1 is a single-edge boring reamer structural view, which is characterized by: (1) at the back of the cutting edge 90 ° and 180 ° position has two guide bearing block, the cutting edge and the outer diameter of the bearing block are located on the same circumference . The cutting edge blade and the bearing block are made of YG6. (2) The cutting edge is divided into three parts, inner and outer, oblique edge, knife
