ZYB-400T CNC Electro-Hydraulic Servo Press Brake

1、Overall welded and processed structure.
2、Closed loop control mode composedof electric-hydraulic servo valve and measure ruler,ensure the highest controlling precision.bending accuracy and repositioning accuracy are also reach the highest level.
3、Backgauge mechanism can control several backgauge axes.
4、Integrated hydraulic system decreases the pipe connetions,oil leakage,and increases the stability and overall beautifies.
5、Hydraulic compensation mechanism heips to prevent the deformed slider from affecting the quality of the workpiece,and the compensation mechanism is adjusted automatically by the CNC controller which is convenient and accuracy.
6、NC controller uses HOlland DELEM, Italy ESA or Swiss CYBELEC with Multi-languages.

Relationship between “Ton” and bending thickness:

"Ton" =65×thickness×thickness×length/(width of groove), width of groove= 8×thickness

Ton=65×T²×L/8×T, T=8×Ton/(65×L)

For model ZYB-400Ton×4000mm

400=65×T²×4/8×T, so thickness of normal steel plate T≈12.3mm

The Max metal sheet plate to bend by ZYB-400Ton×4000mm has size 12.3×4000mm
