This machine is a numerically controlled four-roller plate bending machine, which adopts PLC control. The system is pre-installed with programs of several shapes such as circle, square, ellipse and cone (specific), and only needs to call out the corresponding program to process. The user can also input other programs according to the production needs to meet the requirements of processing workpieces of different shapes. The characteristics of this machine are simple, convenient, fast and good processing effect. At the same time, the numerical control system and electrical components adopt well-known domestic and foreign brands to ensure the processing quality and the service life of the machine.
