我厂广大工人和技术人员,总结了自己十余年加工叶片的经验,吸收了瑞±S4铣床的优点,设计制造了加工叶轮机大叶片型线(见图1)的双向液压靠模仿形铣床。该铣床自投入生产后,实践证明运行可靠,加工质量稳定(型线精度为0.1毫米漏光,光洁度△6),生产率比S4铣床提高约50%。 根据叶片 The vast majority of workers and technicians in our factory summed up their experience in processing blades for more than ten years and absorbed the advantages of Swiss ± S4 milling machine. We designed and manufactured a bi-directional hydraulic model-based profile milling machine for processing large blade profiles of impeller (see Figure 1) . The milling machine since put into production, the practice proved reliable operation, processing quality and stability (profile accuracy of 0.1 mm light leakage, finish △ 6), the productivity increase of about 50% compared with the S4 milling machine.
