PR CNC Press Brake

1. Main Features:

• Brand-new industry design combined with modern aesthetic concept, high-quality production technology with simple appearance.
• Latest high-frequency responding hydraulic control technology, faster, more efficient and higher accuracy.
• Heat treatment of the machine frame, rigidity optimization verification on entire machine and the application of hydraulic compensation structure jointly ensure the bending precision of MB8 series Press Brakes.
• Optimal ratio of parameters and top-level core configuration ensure stable performance, and easy operation.
• MB8 standard 2axis backgauge system, as for complicated shape work piece, 4 or 5 axis backgauge system and corresponding dies are available for your option.
• Press Brake using fully 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 on the same frequency, maintaining the parallel state of the worktable.
• According to process state of sheet metal, CNC system can automatically control the table deflection compensation value resulting in uniform length and angle of all workpieces.
• The use of hydraulic deflection compensation gives access to uniform full length workpieces. Hydraulic deflection compensation consists of a set of oil cylinders in the worktable, which can make the table occurs relative movement and form an ideal convex curve, ensuring the relative position relations with slider keep unchanged. Compensation values are subject to plate thickness and properties of material to be cut.
