TECHNICAL FEATURES
- European hydraulic CNC Brake Press Machine controller, with full CNC controlled Y1, Y2, calculation based on material and tool library;
- Automatic bending procedure optimization by CNC controller, engineer can adjust the steps according to actual design;
- Y1, Y2 is measured with high accurate optic scalars. Measured signal will be feedback to CNC Hydraulic Press brake controller timely.
- European proportion valves will control left and right cylinder’s movement according to CNC hydraulic Brake Press controller’s command.
- Back gauge is with long pitch – precision ball screw and liner guide. Moving speed is higher; repeat accurate is higher;
- Hydraulic CNC Brake Press Machine Back gauge is driven by servomotor for X-axis. There are optional R, Z-axis.
- Back stop fingers are with two steps, which will convenient for various part fabrication;
- Ram guide is with low friction Polymer wear-resistant materials, which will give CNC Brake Press Machine long accurate working life;
- Working table is with automatic crowning system. Hydraulic type is for up to 200T-3.2m machines, while wedge structure is applied for bigger machines.
- For bending force up to 200T CNC Brake Press Machine, quick clamp for punch is applied. It will be easy handle the up tooling. The clamp has wedge crowning adjust system.
- Side and rear protection fences are standard for up to 200T machine. For bigger machine, optic safety sensor will be optional.
- Low noise and high efficient gear pump is standard configuration;
- Ram is with Anti-tilt device for machine protection;
- CNC Press Brake Oil tank is with level and temperature indicator.
- 200T CNC Hydraulic Press Brake machine is equipped with standard goose neck punch. which is suitable for sheet panel, kitchen instruments, office instruments, elevator, show case or metal door. Bottom die can be multi-V die, which is suitable for various general functions. It also can be 2-V / single-V die, which will be more professional tool design for proper products.

Estimate Bending Force Calculation or Max Bending Thickness for CNC Brake Press 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:
- The hydraulic CNC 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 Brake Press 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 Brake Press Machine Shipment, Unloading, Installation Related Issues
- The CNC Brake Press 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 Machine 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 Brake Press Machine, 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 CNC Brake Press Machine 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 Brake Press Machine, 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.
