An electro-hydraulic servo CNC bending machine is a high-precision CNC bending device that utilizes electro-hydraulic servo control technology. It combines the advantages of electrical control and hydraulic drive, and is widely used in sheet metal processing in the automotive, aerospace, and building curtain wall industries.
Its core features include:
High-precision closed-loop control: A fully closed-loop control system is formed using imported German electro-hydraulic servo valves and HEIDENHAIN linear encoders, providing real-time feedback on the slider position. Repeatability accuracy can reach ±0.01mm, with a maximum of 0.005mm.
Energy-saving and efficient: Utilizing a dual servo pump control system, hydraulic oil consumption is only 1/3 to 1/5 of traditional systems, standby energy consumption is reduced by more than 75%, and working speed is increased by 15%-25%.
Intelligent compensation technology: Equipped with an electromechanical convex automatic compensation system, the CNC system automatically adjusts the slider deformation compensation amount to ensure consistent bending angles throughout the entire length.
Stable and Reliable Structure: The machine body adopts an integral welded structure made of all-steel plates, undergoing tempering and vibration stress relief treatment, and its rigidity and stability are optimized through ANSYS finite element analysis.
Advanced CNC System: Supports high-performance CNC systems such as DELEM (Netherlands) and ESA (Italy), featuring automatic selection, program calculation, 3D graphics display, and robot bending functions.
Low Noise and Long Lifespan: The servo main motor uses closed-loop control to manage hydraulic pressure, resulting in standby noise of approximately 25 decibels, stable oil temperature, and extended service life of hydraulic components.
