This type of cutting machine can indeed achieve a good cutting effect on metal pipes.

[0003] However, the cutting machine is not equipped with a good metal pipe moving structure. After a section of metal pipe is cut, the worker needs to stop the machine, move the remaining metal pipe, and then re-clamp the moved metal pipe, which will reduce the cutting efficiency of the metal pipe. When the worker takes the remaining metal pipe and re-clamps it, the heat generated during the cutting of the metal pipe and the burrs and debris on the surface of the metal pipe will damage the worker's hands, which will cause great safety hazards when cutting metal pipes.
