摘要
F系列钻井泵液缸内孔形位公差要求精度较高,特别是锥孔加工难度较大,需要利用滚压工装完成加工。加工液缸时保证形位公差要求和锥孔粗糙度要求,可以提高液缸的使用寿命。
F Series Drilling Pumps fluid cylinder Inner bore Geometrical tolerance requires high accuracy,In particular,the processing of taper holes is more difficult,Rolling tooling is needed to complete processing.Guarantee the requirement of Geometrical tolerance and taper hole roughness in processing fluid cylinder,It can improve the service life of fluid cylinder.
