Is it better for Electro-hydraulic servo bending machine or Hybird Electric bending machine?

Electro-hydraulic synchronous CNC bending machine on both sides of the main cylinder synchronous proportional electro-hydraulic servo valve hydraulic control system, and grating ruler formed closed-loop control, respectively by the CNC independent restrictions, feedback accurate data to ensure accurate slider operation accuracy.

Electro-hydraulic servo bending machine: the computer controls the flow and pressure of Y1 and Y2 cylinders respectively through two sets of servo two-way pump systems, and drives the oil in the upper chamber of the cylinder directly into the lower chamber of the cylinder through the oil pump to realize the lifting of the upper mold. The reverse of the oil pump drives the oil in the lower chamber of the cylinder directly into the upper chamber of the cylinder to realize the bending of the plate.  The synchronization of the left and right sides of the upper die is controlled by two sets of servo two-way pumps respectively.  Machine tool not only high precision, energy saving, low noise, and more stable and reliable, less oil, conducive to the manufacture of large stroke ultra-high speed bending machine  

The previous bending machines are torsion shaft synchronous bending machine or valve controlled bending machine, oil-electric hybrid servo CNC bending machine is the real pump controlled bending machine, machine synchronization depends on pump control

Electro-hydraulic synchronous CNC bending machine and oil-electric hybrid bending machine is like a tractor and a car, in different types.  Compared with the two, the former is cheap and suitable for bending large sheet metal. The NUMERICAL control bending machine is more cost-effective than 250T.  The latter, in addition to the high price, other advantages, through two sets of servo two-way pump system respectively control the flow and pressure of Y1, Y2 cylinder, respectively, the oil in the upper chamber of the cylinder directly through the pump into the lower chamber of the cylinder, to achieve the upper die lifting.  Oil pump inversion directly drives the oil in the lower chamber of the oil cylinder into the lower chamber of the oil cylinder to achieve bending under pressure of the upper die.  Suitable for 160T-250T, fast down 200mm/s, return 200-350mm/s, the synchronization of the left and right sides of the machine tool is controlled by two sets of servo two-way pumps respectively.  Machine tool not only high precision, small friction, high synchronization, energy saving, low noise, and energy saving, fuel saving, more stable and reliable, occupy a small space, conducive to the manufacture of large stroke ultra-high speed bending machine.
