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团结处相贯线孔、相贯线端部、弯头（虾米节)举行自动盘算和切割的装备。该机普遍运用于修建、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。数控相贯线切割性能十分利便的切割加工此类工件，无需操作盘算、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.
