Sheet Metal Press Brake CNC Controled 400T

400t cnc hydraulic press brake machine

With improved requirements on sheet metal bending capacity, We started to make bigger CNC Sheet Metal Press Brake from 1980's. 400T sychro bending press machine is equiped with Netherland made CNC controller, Bosch or HOERBIGER Germany made hydraulic system, Japan made hydraulic pump, YASKAWA servo motor. All world-famous components will make machine more stable and stronger in heavy workpiece fabrication. We developed various length machine according to customer's sheet metal bending, 3.2/4/5/6/7 will be selection.

FEATURES OF MACHINE:hydraulic CNC press brake machine 400t
  1. CNC Sheet Metal Press Brake With Stylish design, high rigidity, high speed;
  2. Electro-Hydraulic servo system, Closed loop control system controls accuracy;
  3. Sheet Metal Press Brake Worktable adopts hydraulic deflection compensation to ensure the accuracy of workpiece;
  4. Back gauge is driven by servo motor, adopted ball-screw and linear guide way, it could make sure Sheet Metal Press Brake positioning accuracy
  1. Estimate Bending Force Calculation or Max Bending Thickness for CNC Sheet Metal Press Brake

    Estimate bending force calculation formula is 

     P=650*S*S*L/V

    • P:  Estimate Hydraulic press Brake Bending force (T)
    • S:   Plate thickness (mm)
    • L:   Bending Length (m)
    • V:   Hydraulic Press Brake Bottom die V opening width (mm)

    NOTE:  

    1. The CNC Sheet Metal Press Brake bending force calculation is based on mild steel (tensile strength = 450Mpa). For other material, we shall time constant K (related with material tensile strength, hardness, elongation). for example, Stainless plate characters can be different according to plate number. we can set K=1.5.
    2. Normally V (CNC Sheet Metal Press Brake bottom die V opening width) can be 6 ~12 times plate thickness. for thin plate we select smaller V opening. while for bigger and Harder plate, we shall set bigger V opening. Bigger V will introduce bigger bending radius.
  2. CNC Sheet Metal Press Brake Shipment, Unloading, Installation Related Issues
    • The CNC Sheet Metal Press Brake will be loaded over steel rack. During loading / unloading, we shall pull or push only over the steel rack to avoid deforming on machine body frame.
    • On Sheet Metal Press Brake wall frame, there are lifting hook. We shall use enough length steel wire rope or chain to lift the machine by the hook. We shall be careful to avoid machine drop down;
    • For bigger capacity CNC Sheet Metal Press Brake, the machine height can be close to container door top. when we pull machine out, we shall be careful to avoid damage on machine top parts. To protect the parts, we may remove hydraulic valve, motor or other components on top. Please reinstall the parts according our guide.
    • The CNC Sheet Metal Press Brake will be fixed by chain or steel wires inside the container, covered with plastic film to avoid moisture during ocean shipment.
    • When receive the CNC Sheet Metal Press Brake, Customer shall remove the steel rack under the machine, prepare foundation for the machine. Good fix and levelling will make machine work longer and accurate.
