Electro-hydraulic servo CNC press brake has a frame structure with an all-steel integral welding design. By annealing to eliminate internal stress, it ensures the overall precision of the machine tool. With excellent rigidity, it offers exceptional resistance to distortion and tilt. The thickened worktable plate and slider enhance the machine rigidity significantly. Thus, in bending, both the slider and worktable have minimal deformation, ensuring outstanding straightness and angle consistency of the workpiece.
Capable of bending various metals and pliable acrylic materials, offering a diverse range of specifications and configurations tailored to meet customer requirements, including bending length and thickness.
Reliably process a variety of materials, including high-strength plates like aluminum plates, stainless steel such as 201 and 304, brass, manganese steel pipes, T700 and T1000.
High precision, surpassing the precision of standard CNC bending machines by 60%.
With its imported intelligent system, the machine can autonomously calculate the required bending pressure, taking into account factors such as plate thickness, material type, and length. Moreover, it has the capability to automatically generate arc bending programs.
The standard 4+1 axis model notably reduces the reliance on manual expertise and lessens workload, thus having enhanced work efficiency.
The system offers flexibility as different systems and modules can be replaced to align with specific customer requirements.
Optional configurations such as 6+1 axes and 8+1 axes are also available.
The mechanical structure of this machine tool primarily consists of the frame, worktable, slider, main oil cylinder, and back gauge. With refined design and manufacturing processes, it effectively ensures the precision of both manufacturing and operational use of the machine tool.
The cylinder is forged as a single part, while the piston rod undergoes triple chrome plating and mirror surface treatment, providing effective wear resistance and precision. This makes it a simple and stable structure.
1. Complete seal sets from Japan's NOK are employed to minimize the risk of oil leakage.
2. Using electro-hydraulic servo technology not only ensures high precision but also enhances response speed.
3. Introducing the original roller-type four-point guide rail technology, which, unlike other similar products, eliminates the risk of guide rail separation. This significantly improves the safety, stability, and processing precision of the machine. Compared to rack transmission technology of the same level, the service life is increased by at least five times.
