摘　　要：低压涡轮轴是保证航空发动机稳定性的重要组件,其内孔加工质量直接影响航空发动机的性能。针对低压涡轮轴的结构与材料分析,结合深孔钻削的加工特点,制定了合理的加工工艺方案。通过对加工零件的理论分析和经验分析,选择合适的加工刀具进行深孔钻削试验,并确定了钻削参数组合为主轴转速n=170r/min,进给量f=0.06mm/r,切削液流量为Q=110L/min。使用该套工艺参数进行零件加工,经检测,加工内孔直径、表面粗糙度和孔直线度均满足产品加工要求。Low pressure turbine shaft is an important component to ensure the stability of aero-engine.The machining quality of inner hole directly affects the performance of subsequent aero-engine.According to the analysis of the structure and material of the low pressure turbine shaft, combined with the processing characteristics of the deep hole drilling, the reasonable processing technology is formulated.Through the theoretical and empirical analysis of the machining parts, the appropriate machining tool is selected and the drilling test is carried out.The drilling parameters are determined: the spindle speed n=170 r/min, the feed rate f=0.06 mm/r, and the cutting fluid flow Q=110 L/min.With the above parameters, the inner hole diameter, surface roughness and straightness of the hole can meet the processing requirements.
