该系列数控相贯线切割机是一种对钢管和有色金属管子的结合处相贯线孔、相贯线端部、弯头（虾米节)进行自动计算和切割的设备。该机广泛运用于建筑、化工、造船、工程机械、冶金、电力等行业的管道结构件的切割机。数控相贯线切割机能十分方便的切割加工此类工件，无需操作计算、编程，只需输入管道相贯系统的管子的相贯线、相贯线孔及焊接坡口。

This intersecting line cutting machine can automatically calculate and  cut the profiles of intersectionposition, profile position edge, elbow, etc. It is mainly applied to the processing of piping structures in industires of construction, chemical, shipbuilding,engineering machinery, metallurgy,electric power etc. It is quite convenient to machine above mentioned workpieces without additional operational computing and programming but simply input the dataof intersection position, hole position and bevel.
