盖盘铣制三元叶轮叶片侧刃加工的工艺方法
摘要：
本发明提供了一种盖盘铣制三元叶轮叶片侧刃加工的工艺方法，包括翻前装卡并找正、翻前粗加工、翻前轮毂与前缘的精加工、翻前叶片精加工、铣找正平面、翻后装卡、翻后找正、翻后粗加工、翻后吸力面叶片精加工、翻后压力面叶片精加工、翻后轮毂精加工等加工过程。本发明提供的一种盖盘铣制三元叶轮叶片侧刃加工的工艺方法，不仅能保证叶片的加工精度，而且能够大大缩短叶片的加工时间，大幅度提高叶轮的加工效率。
摘要（英）：

The invention provides a technological method for side edge machining of cover-disk milled 3-D impeller blades. The technological method comprises the following steps of pre-turning installing and clamping and aligning, pre-turning rough machining, pre-turning wheel hub and leading edge finish machining, pre-turning blade finish machining, milling for plane aligning, post-turning installing and clamping, post-turning aligning, post-turning rough machining, post-turning suction surface blade finish machining, post-turning pressure surface blade finish machining, post-turning wheel hub finish machining and the like. The technological method for the side edge machining of the cover-disk milled 3-D impeller blades not only can ensure the machining precision of the blades, but also the machining time of the blades can be greatly shortened, so that the machining efficiency of the impeller is greatly improved.
