1.  Main Features:

Brand-new industry design integrated with modern aesthetic concept, high-quality fabrication technology with simple and elegant appearance.
Latest high-frequency responding hydraulic control technology, higher speed, more efficient, higher precision.
Heat treatment of the rack, rigidity optimization verification of entire machine, research and application of hydraulic compensation mechanism jointly guarantee bending precision of MB8 series Press Brakes.
Optimal ratio of parameters and top-level core configuration ensure stable performance, easy operation.
MB8 standard 2 axis backgauge system, as to complex shape work pieces, 4 or 5 axes back gauge system and corresponding dies are available for bending of complicated shaped workpieces.
Press Brake using closed-loop electro-hydraulic servo control technology, slider position signals can be feedback to NC system by bilateral gratings, then NC system adjusts the amount of fuel tank by changing the synchronous valve opening size, hereby controlling the slider (Y1,Y2) running with same frequency, maintaining the parallel state of the worktable.
As for different plate, CNC system can automatically control the table deflection compensation resulting in uniform length of all workpiece angles.
The use of hydraulic deflection compensation gives access to uniform full length workpieces . Hydraulic deflection compensation consists of a set of oil cylinders, which can make the table occurs relative movement and form an ideal convex curve, ensuring the relative position relationship with slider keep unchanged. Compensation values are subject to plate thickness and properties of material to be cut.
