The bending machine imported from Belgium was originally controlled by a rotary valve.SynchronizeThe structure has been fully transformed into an electro-hydraulic servoSynchronous CNC bending machine, the bending machine system adopts the DA-52S controller of the Dutch DELEM company, the hydraulic system adopts the proportional servo valve of the German Rexroth company, and the grating ruler is installed on both sides of the machine tool to feedback the slider position in real time. After the transformation, the speed of the whole machine isbendThe precision is further improved, and the back gauge is changed from the original manual type to the servo motor CNC adjustment, which greatly reduces the labor intensity of workers and improves the positioning accuracy.
