Main Performance ：

Y1，Y2 Axis------Two linear scales installed at both sides of ram to control cylinders.
The frame of machine is composed of tank, worktable, left and right housings and ram.

So it has high strength and good rigidity

Synchronization working principal

The Press brake Adopting electric-hydraulic proportional valve to ensure the synchronization of both cylinder. The proportional valve is made by BOSCH-Rexroth company with very good performance such as small friction between mechanic action pairs, fine electronic amplifier and electric magnet with high controlling force and continuous action. There are two raster displayers on both sides of machine to get signal of the position of ram continuously and feed back the signal to control system, then the control system will control electric-hydraulic valve to make two cylinders synchronization on one machine.

Another Because the raster displayers are installed to “C” plates, not on housing plates directly, the deflection of ram and frame when working will not effect its measuring and controlling precision
About two units Synchronization working principal:

If need two units working together, only need to rotate the switch to Synchronization position on the control panel of the main unit. Both unit position signal will be sent to CNC control system (Delem system), and output signal from CNC system will sent to proportional valve and prefill valve. To control fast down, speed change point, pressing speed and return speed to keep the two unit Synchronization with high precision

Through computer，the operator could communicate with machine. The computer has several service language, calculate and adjust the bending force automatically. Also it could calculate and control the dead point, speed changing point.The strokes (Y1, Y2) of ram could make a small tilt to meet the special requirement of user.
Equipped with good guiding system, position measuring system and hydraulic balance system to meet the requirements of full length job and eccentric job.
Worktable compensation unit is adopted to make up for deflection of machine when working to make sure the precision of work piece
The surface of cylinder has good wearing and heat treatment, so it has good lubrication and long service life
