在镗床上加工的零件,孔口都要倒角。过去我们是用单刃倒角刀,镗杆端部有螺孔,用螺钉固定倒角刀,然后进行倒角,比较麻烦,特别是碰到箱体类零件,因为手不易伸进去用扳手紧固螺钉。后来我们从镗床浮动刀上受到启发,制作了如图所示的实用的四刃倒角刀,效果很好。现介绍如下。 Boring machine in the processing of parts, the hole should be chamfered. In the past we are single-blade chamfering knife, boring bar end of the screw hole, chamfering the knife with a screw, and then chamfering, more trouble, especially encountered parts of the box, because the hand is not easy to reach tight with a wrench Screws. Later, we were inspired from the boring machine floating knife, produced a practical four-edge chamfering knife as shown, the effect is very good. Now introduced as follows.
