TECHNICAL FEATURES
- First, our CNC Hydraulic Press Brake Machine is with European controller. And controller will fully control Y1, Y2. It can calculate based on material and tool library.
- Automatic bending procedure optimization is by CNC controller. Also 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 controller timely.
- European proportion valves will control left and right cylinder’s movement according to controller’s command.
- Back gauge is with long pitch – precision ball screw and liner guide. Moving speed is higher; repeat accurate is higher;
- 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 long accurate working life for CNC hydraulic Press brake;
- 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, 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;
- Oil tank is with level and temperature indicator.

Estimate Bending Force Calculation or Max Bending Thickness for CNC Hydraulic Press Brake Machine
Estimate bending force calculation formula is
P=650*S*S*L/V
- P: Estimate Hydraulic press Brake Machine Bending force (T)
- S: Plate thickness (mm)
- L: Bending Length (m)
- V: Hydraulic Press Brake Machine Bottom die V opening width (mm)
NOTE:
- The CNC Hydraulic press brake machine 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 (hydraulic CNC press brake 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.

Hydraulic CNC Press Brake Machine Shipment, Unloading, Installation Related Issues
- For capacity over 300T-4m CNC hydraulic press brake machine, we will have to disassemble the machine during shipment. the structure is bolted structure. Normally there are big parts like working table, ram, side frames, oil tank frame and cylinders.
- For big capacity hydraulic CNC press brake machine, ram and working table can be higher to get good rigidity. We have to make lower foundation, so that operation height will be about 900~1000mm.
- We will arrange our engineers to customer side for hydraulic CNC press brake machine installation and training. Related cost is not included normally. we need to confirm it before order.
