Electro-hydraulic servo press brake electro-hydraulic synchronous press brake which is better

From the nature of the CNC bending machine synchronization, it can be divided into three types, namely, the torsion axis synchronization, the hydraulic proportional valve synchronization, and the dual servo pump control synchronization. 

Twisted shaft synchronization: Forced mechanical synchronization with torque.

Hydraulic proportional valve synchronization: The travel position of the left and right cylinders is transmitted to the computer through the grating scale or the magnetic scale. The computer controls the synchronism of the two cylinders through the electro-hydraulic proportional valve.

Double servo pump control synchronization: the travel position of the left and right cylinders is transmitted to the computer through the grating scale or the magnetic scale. The computer controls the stroke, speed, position and pressure of the left and right cylinders by controlling the displacement and pressure of the oil pump by the servo motor. Synchronization of the left and right cylinders.

For the precision of processing machinery, more customers have higher requirements for CNC bending machines. The torsion-axis synchronous CNC bending machine was born in the early 1980s with low precision and no error feedback. The bending slider has poor anti-offset load capability; the hydraulic proportional valve is synchronized with the last century, with high precision and real-time error feedback. The bending slider has strong anti-offset load capability.
