Description
The CNC press brake adopts BiD-SVP bidirectional pump electro-hydraulic servo system. BiD-SVP means bidirectional servo pump. The BiD-SVP bidirectional pump electro-hydraulic servo system has advantages of high energy saving, minimization of idle work, improvement of production efficiency etc., which can directly reduce much electricity expenditure for users, as well as minimize the consumption of hydraulic oil. In addition, it can greatly reduce CO2 emission and environmental pollution.

Features
1.Energy saving: Compared with traditional transmissions, it saves 70% of power consumption.
2.High efficiency: The working efficiency can be improved by 30% (reduce the cycle time).
3.Accurate: The positioning accuracy is higher that can be up to 5um.
4.Quiet: Reduction of noise makes the machine tool quieter during work.
5.Less consumption: The hydraulic oil consumption is little, only 20% of traditional ones.
6.Easy: The machine tool is easier for manufacturing, maintenance and commission.

Advantages
1. Minimize overflow loss.
2. Stepless speed regulation. Adjustment range: 0 to maximum.
3. Set up proportional valve control to reduce throttling loss.
4. Accurate needed oil distribution optimized by the speed of dynamic servo motor.
5. Set up with idle power: the servo motor can be closed when no flow or pressure is required.
6. The unique design of normally open type of charging valve enables hydraulic compensation control.
7. Compact design, easier installation.
8. The difficulty of oil cylinder processing is lowered and the cost reduced.
9. For machine tool manufacturers, the change is small and easier for manufacturing.

Electro-mechanical compensation
The deflection compensation mechanism of this machine adopts the mechanical deflection workbench compensation structure, with automatic calculation and control by numerical control system.

1. During working, the lower compensation workbench generates an upward force equivalent to the force of the main oil cylinder to the workbench, and thus an upward convex curve is produced to compensate the deformation of the workbench and the slider in the process.

2. Composed of a certain number of three-dimensional curved surfaces with different slopes that makes up for the shortcomings of the traditional hydraulic compensation blind zone, the compensation curve is closer to the real deformation curve of the slider, thus greatly improving the machining accuracy of the press brake.

Standard configuration includes a set of standard molds, portable and fast for mold replacement.
Adopting overall quenching process gives high hardness and good wear resistance.
