The CNC steel bending machine is a mechanically controlled bending machine to replace the artificial bending machine. It mainly processes the bar steel bar and can bend the national standard steel bar within 50mm. The equipment can process multiple steel bars at one time, and has the advantages of processing shape standard and large processing capacity. It can replace 20-30 people. The equipment can be used with the CNC steel cutting production line, or it can work alone to automate high-volume bending of steel bars for construction.
