It is widely used in many industries such as metal processing, light industry, aviation, shipbuilding, metallurgy, home appliances, construction, electronics and automobiles. In these fields, the bending machine can realize accurate and efficient bending operations on metal sheets, so that the workpieces can reach the required shape and size;
