Product features: The series CNC cutting machine is a kind of equipment that can automatically calculate and cut the through line hole, through line end, elbow (shrimp joint) for various steel pipes and nonferrous metal pipes. This machine is used widely in the cutting of pipeline components in such industries as construction, Chemical, shipbuilding, machinery engineering, metallurgy, electricity etc. It is very convenient for the series cutting machine to process this kind of workpieces, without calculation, programming but inputting the pipe radius, through angle etc for the pipe through system, then the machine can automatically cut the through line hole and welding bevel of the pipe.
