我厂在加工外径为中130公厘的齿轮锻坯时,由于材料较硬,用高速钢刀车削槽子(宽8公厘,深40公厘)很困难,效率也很低。后来改用硬质合金刀分两次车,效果仍不好。最后由施工科研究改用两把刀同时车,质量和产量都有提高。改进后方法如附图所示,把AB两把硬质合金割刀成相对方向压在刀架上,刀尖与工件中心平,而两把刀的径向位置错开,使每把刀担负切削槽宽的 When machining a gear forging with an outer diameter of 130 mm, our mill is hard to cut with a high-speed steel knife (8 mm wide and 40 mm deep), and the efficiency is very low. Later switched to carbide carved knife twice, the effect is still not good. Finally, by the construction section to switch to two knives at the same time car, quality and production have increased. The improved method as shown in the figure, the two AB carbide cutter into the relative pressure on the knife holder, the tip and the workpiece center level, and the two radial position of the knife staggered, so that each knife responsible for cutting Groove width
