該系列數控相貫線切割機是一種對鋼管和有色金屬管子的結合處相貫線孔、相貫線端部、彎頭（蝦米節)進行自動計算和切割的設備。該機廣泛運用于建筑、化工、造船、工程機械、冶金、電力等行業的管道結構件的切割機。數控相貫線切割機能十分方便的切割加工此類工件，無需操作計算、編程，只需輸入管道相貫系統的管子的相貫線、相貫線孔及焊接坡口。

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.
