FEATURES OF MACHINE:
- First , our CNC Sheet Metal Bending Machine is With Stylish design, high rigidity, high speed;
- Electro-Hydraulic servo system, Closed loop control system controls CNC press brake accuracy;
- Worktable adopts hydraulic deflection compensation to ensure the accuracy of workpiece;
- Back gauge is driven by servo motor, adopted ball-screw and linear guide way. For sure that it could make sure positioning accuracy.

Estimate Bending Force Calculation or Max Bending Thickness for CNC Sheet Metal Bending Machine
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:
- Theoretically CNC hydraulic 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.
- Normally V (CNC Sheet Bending Machine 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.

CNC Sheet Metal Bending Machine Shipment, Unloading, Installation Related Issues
- Normally CNC Sheet Metal Bending Machine 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 hydraulic press brake wall frame, there are lifting hook. First, We shall use enough length steel wire rope or chain to lift the machine by the hook. Make sure that We shall be careful to avoid machine drop down;
- For bigger capacity Sheet Metal Bending Machine, Maybe 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 Hydraulic 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 press brake, Customer shall remove the steel rack under the machine and prepare foundation for the machine. Good fix and level will make machine work longer and accurate.
