Hydraulic system is from Bosch -Rexroth, Germany.
When the oil comes out from the pump, all the way into the pressure cylinder first presses the sheet material, and another routing time relay controls the delay to enter the left cylinder upper chamber for about 2 seconds. The oil in the lower cylinder of the left cylinder is forced into the upper cylinder upper chamber and the right cylinder lower chamber. Oil back to the tank. The return stroke is reversed by the solenoid valve
DA66T CNC controller
The new generation DA-Touch controls offers an even higher grade of efficiency in programming, operation and control of today's CNC hydraulic press brake machine. Ease of use combined with state-of-the-art technology go hand in hand, improving productivity. The touch screen gives access to the proven Delem user-interface and enables direct navigation between programming and production. Functions are directly located where you need them, offering optimized ergonomics throughout the application. The DA-66T offers 2D programming that includes automatic bend sequence calculation and collision detection. Full 3D machine set-up with multiple tool stations giving true feedback on the product feasibility and handling.
