Sheet Metal Bending Machine KRRASS 4 Axis CNC Press Brake MB8-160T/5100 2 Axis Backgauge
Main Features:
- New industry design combined with modern aesthetic concept, high-quality production technology, simple appearance.
- Latest high-frequency responding hydraulic control technology, faster, more efficient and high precision
- Heat treatment of the rack, 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.
5.MB8 standard 2 shafts back gauge system, as to complex shape work pieces ,4 or 5 shafts back gauge 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 state of sheet metal on the Press Brake, CNC system can automatically control the table deflection compensation yielding uniform length of all work piece angles.
- The use of hydraulic deflection compensation gives access to uniform full length work pieces. Hydraulic deflection compensation consists of a set of oil cylinders under 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.
