摘　　要：针对汽轮机阀壳内腔深孔余量检测困难、准确度不高的问题,探讨一种新的检测方式。为了提高阀壳内腔深孔加工的可靠性,采用专用镗杆,有效增强了切削过程的刚性,提高了表面加工质量。In view of the difficulty in allowance inspection of deep hole in inner cavity of valve casing and low accuracy,this paper discusses a new inspection method.In order to improve the reliability of machining deep hole in valve casing cavity,special boring bar is used to effectively enhance the rigidity during cutting and improve the quality of surface machining.

关 键 词：阀壳 深孔 检测 专用镗杆
