在车床上加工梯形螺纹和蜗杆时,由于刀具是三个切削刃,切屑在螺纹槽内容易阻塞,往往损坏刀具,甚至使工件变形,造成废品。如果先切槽,再成形加工,不仅效率低,而且在切槽时也难免损坏刀具和工件。针对这一问题,我们采用了双向进刀架(图1),把切槽刀和成形刀分别装在两个方向,同时进刀,经过使用,效果较好,提高了工效,也保证了质量。现介绍如下。 When machining trapezoidal threads and worms on a lathe, since the tool is three cutting edges, the chips tend to clog in the thread grooves, often damaging the tools and even deforming the workpiece, resulting in waste products. If the first slotting, then forming processing, not only inefficient, but also inevitably cut in the cutting tool and workpiece. In response to this problem, we use a two-way into the knife (Figure 1), the grooving knife and forming knife were installed in two directions, respectively, while the knife, after use, the effect is better, to improve work efficiency, but also to ensure the quality . Now introduced as follows.
