The electric and hydraulic servo system can control the synchronization of two cylinders. Combined with optical curtain of international standard, the fully closed loop control is formed with high synchronization control accuracy, and high bending and repetitive positioning accuracy.

2. The CNC cylinder deflection auto compensation system helps to prevent the deformed sliding block from affecting the workpiece quality and ensure its good linearity and bending angle. The compensation is adjusted automatically by the CNC system, both convenient and accurate.

3. The full functional backguage system can be extended up to six axises. The workpiece can be bent at whatever angle. D. After welding, the body is machined with the fixture installed ony one time. It is processed by CNC pentahedron machining center, ensuring high rigidity and processing accuracy.

4. The hydraulic system adopts the integrated one, which helps to reduce piping connection, eliminate oil leakage, improve the work stability, and beautify the machine appearance. The inner engaged gear pump manufactured by a famous German company is used to reduce the system noise and extend the service life.

5. The die sections have different lengths, which can be combined with a certain width to meet the processing requirements of special workpieces.

6. The upper die hydraulic automatic fastener or quick fastener and plug-in lower die can be equipped based on the customer requirement to reduce work load and improve productivity.

7. The numeric control system refers to numeric-control system specialfor electrohydraulic servo bending machines of Italian ESA,Netherland DELEM,or Swiss CYBELEC Companies,alble to achieve the functions of graphic programming for bending angle,compensation for angle amendment,automatic calculation and adjustment of bending pressure,automatic calculation of compensation for workbench distortion,extending length of workpiece ,bending pressure for sole pressing,open distance,and automatic withdrawal of rear stopper,etc.
