Rod body cutting system

The embodiment of the invention provides a rod body cutting system which comprises a rod body fixing mechanism used for fixing a to-be-cut rod body; the linear cutting mechanism is provided with an annular cutting line, and the part, used for cutting the rod body in the moving process, of the cutting line is a cutting section; the power feeding mechanism comprises a pulse power supply, the positive electrode of the pulse power supply is connected with the rod body, and the negative electrode of the pulse power supply is connected with a cutting line; wherein the linear cutting mechanism and the rod body fixing mechanism can move relatively, so that the cutting section is cut in the axial direction of the rod body, and the pulsed power supply, the cutting section and the rod body form a discharge loop to perform electric spark discharge cutting on the rod body. According to the rod body cutting system, the rod body is cut in a composite mode and comprises cutting section cutting and electric spark discharge cu
