我们曾接受车削一批小轴零件(见图1)的任务,小轴材料为45钢,零件细而长,光洁度和精度要求也较高,用普通车削方法是很难加工的。我们学习兄弟厂先进经验,设计制造了一套加工特细长小轴车削工具,完成了该项任务。特细长小轴车削工具的结构及车削示意图见图2。支承套6固定在支杆5上,必要时在工具架2上同样加一支承套,车刀体12固定在支杆3上,支杆3 We have accepted the task of turning a small number of small shaft parts (see Figure 1), the small shaft material is 45 steel, thin and long parts, smoothness and precision are also higher, with the ordinary turning method is difficult to process. We learn the advanced experience of Brother factory, designed and manufactured a set of special slender long axis turning tools to complete this task. Slender small axis turning tool structure and turning diagram shown in Figure 2. Supporting sleeve 6 is fixed on the strut 5, if necessary, the same on the tool holder 2 plus a bearing sleeve, body 12 is fixed to the strut 3, the strut 3
