Then, the cutting plate motor 7-3 and the motor in the rotation driving mechanism 9-3 are started, driving the rotating cutting plate circular knife 7-1 to move along the cutting tool groove 10, and then cutting the plate. By setting the pressing plate device 6 and the clamping and positioning device 13, the problem of cutting line deviation of the metal plate during the cutting process can be avoided.
