Large Metal Plates fabricating machine CNC Electro-hydraulic
synchronization Press Brakes
Main features of machine tool,
1. This machine is Electro-hydraulic servo CNC bending machine.
2. Up moving bending design, low noise and stable working state.
3. Y1-Y2 can be programmed separately and work under eccentric load
or special-shaped bending.
4. The worktable adopts DNC controlled mechanical plus convex wedge
deflection compensation worktable. After inputting the data of
sheet thickness, lower die opening and tensile strength into the NC
system, the bending force and the relevant compensation values of
worktable and slider will be determined automatically. Therefore,
the accurate convex amount can be obtained during each bending. In
the process of machining, deflection compensation without blind
area can be realized.
5. At the bottom-dead point, there is a time to pause and maintain
the pressure to ensure the accuracy of the workpiece.
6. Ram synchronization control. Y1 ~ Y2 axes are independent motion
parameters of two oil cylinders controlled by NC system. Two
grating rulers Y1 ~ Y2 are installed at both ends of the machine
tool, which are used to measure the exact distance between the Ram
and the workbench.
7. The machine has the ability to resist eccentric bending.
