WSK CNC Hydraulic Servo Press Brake 125T 4000mm is CNC plate bending machines based on electro-hydraulic servo CNC technology. They typically consist of a CNC control system and an electro-hydraulic servo drive. A servo motor controls a hydraulic pump or proportional valve to achieve high-precision control of the slide and back gauge.
It is more energy-efficient, has a faster response time, and higher precision than traditional hydraulic bending machines. It is suitable for applications such as sheet metal processing, metal component production, electrical cabinet manufacturing, and machining.

The WSK CNC Hydraulic Servo Press Brake 125T 4000mm is characterized by a servo motor replacing the traditional AC main motor. The hydraulic system is controlled by a servo pump or servo proportional valve, resulting in more precise movements, lower energy consumption, and less noise. Compared to traditional CNC hydraulic bending machines, it offers significant energy savings, theoretically reducing energy consumption by approximately 50-60%.
Utilizing optical/magnetic ruler feedback or a servo back gauge system, it achieves high back gauge positioning accuracy and low repeatability.
The slider and back gauge positions automatically compensate for angle errors under CNC control, improving the consistency of bending results.
The 125 T×4000 mm WSK servo CNC bending machine is widely used in:
- Sheet metal processing, metal structural component forming
- Electrical cabinet manufacturing, vehicle body steel plate bending
- Steel structural components, metal enclosures, air duct processing
- Die castings, aluminum plates, stainless steel plates, and other material bending
Its 125-ton bending force + 4000 mm working width configuration allows it to meet the precision bending tasks of medium and thick plates, while also ensuring high automation and positioning accuracy.
