| 摘 要： | 汽轮机滑销系统是保证汽轮机安全高效运行的重要部件之一，其中，Ф50_0＋015mm的骑缝销孔在滑销系统中起着关键的定位作用。由于此销孔特征为深孔加工，所定位的2个零件材质不同，成为汽轮机行业的加工难题。通过对改进加工工艺路线、设计外冷镗刀杆、选择合理的加工刀具和工装以及合理选择润滑油及润滑方式等方面进行综合分析，制定了一套合理的加工方案，有效保证了销孔的加工质量和精度，在同类产品制造中具有广泛的借鉴作用。

| Abstract: | Turbine sliding pin system is one of important conditions to ensure safe and efficient operation of turbine, theФ50_0＋015mm tally pin hole plays a key role n positioning the sliding pin system. Due to this pin holes are deep holes machi- ning and the positioning two parts belong to different materials, it has become the common problem of machining in steam turbine industry. Through comprehensive analysis of technological innovation, design of external cold boring bar, selection of reasonable machining tools and fixtures, the lubricating oil and the lubricating modes and other aspects, developed a set of reasonable processing plan, effectively guaranteed the machining quality and precision of the pin hole, and offered a wide range of reference in similar products manufacturing. |
