摘要：对工业汽轮机外缸中的法兰V型密封槽的加工方法进行分析，通过对端面V型槽加工特征的进一步研究，提出了一种利用数控镗铣床旋风铣快速加工V型密封槽的方法。使用特制的端面V型槽铣刀配合数控宏参数编程旋风铣，可以一次成型加工完成整个V型槽。应用该加工方法，通过试切分析了相应的切削参数与切削量，大大提高了V型密封槽的加工效率和两侧密封面的表面质量。

Abstract:Based on analysis of machining method of the Vshaped seal groove of the new steam flange in outer cylinder of industrial steam turbine，through the further study of the machining characteristics of the Vshaped groove on the end face，a method of fast machining Vshaped seal groove by using the NC boring and milling machine whirlwind milling is put forward.By using special end face Vgroove millingtool and NC macro parameter programming whirlwind milling，the whole Vgroove can be processed at one time.The corresponding cutting parameters and cutting quantity are studied by trial cutting.The processing efficiency of Vtype seal groove and the surface quality of both sides sealing face are greatly improved.
