摘　　要：介绍了汽轮机主汽阀阀碟深孔加工方法,在数控机床进行加工,改造了数控机床原有刀架,设计制造了专用刀架、同心刀杆,提高了刀架最大装夹刀杆的厚度,加大了数控刀架移动的硬行程范围,有效地解决了主汽阀阀碟深孔加工的技术难题。This paper presents the deep - hole machining method for main stop valve disc of steam turbine. The machining is conducted on NC machine. The original tool holder of NC machine is modified, special tool holder and concentric tool bar is designed and manufactured, the max. tool bar thickness of tool holder is increased and the hard travel of NC tool holder is expanded to effectively solve the technical difficulties in deep - hole machining of main stop valve disc.
