在生产中我们采用了加工蜗杆和左旋螺纹的机夹车刀,实验证明具有较好的经济技术效果。下面分作介绍。一、机夹多调式蜗杆螺纹车刀(图1)刀具特点;1.前后刀杆配合后,可上下滑移,车刀前角可优选为0°、8°和14°,变换角度后,切削刃高度仍旧一致,适于粗车、精车及强力切削; In the production we use the processing of worm and left-threaded machine folder turning tool, the experiment proved to have good economic and technical results. The following sub-introduction. First, the machine folder multi-adjustable worm thread turning tool (Figure 1) tool features; 1. After before and after the arbor with, can slide up and down, lathe rake angle may be preferred 0 °, 8 ° and 14 °, Cutting edge is still the same height, suitable for roughing, finishing and powerful cutting;
