过去,我厂加工丝杠,都是用高速钢螺纹车刀。这样,不仅刀具强度差,而且加工效率很低。在推广,应用“优选法”进行的技术革新群众运动中,工人师傅改革了这种落后工艺,采用了硬质合金成形车刀(图1)和跟刀工具架(图2),进行丝杠加工,取得了较好的效果。跟刀工具架中间,有一个长为120毫米的铜质螺纹套2(与丝杠1滑动配合),可防止工件的振动和弯曲变 In the past, I process screw factory, are high-speed steel thread turning. In this way, not only the tool is poor in strength, but also the processing efficiency is low. In popularizing and applying the “Optimization Law” for technological innovation in the mass movement, the worker master reformed this outdated process by adopting a carbide cutting tool (Figure 1) and a knife holder (Figure 2) for screw machining , Achieved good results. In the middle of the knife holder, there is a copper threaded sleeve 2 (sliding fit with lead screw 1) of 120 mm in length to prevent vibration and bending of the workpiece
