SC WSK Single Servo 130T 4000 CNC Press Brake For Sale

SC WSK Single Servo 130T 4000 CNC Press Brake EL15T 4+1 axis is a medium-to-large-sized CNC sheet metal bending machine employing electro-hydraulic servo synchronous control technology. It has a nominal pressure of 130 tons and a maximum bending length of 4000mm. It is primarily used for high-precision bending of carbon steel, stainless steel, aluminum sheets, galvanized sheets, and other metal sheets. This equipment is widely used in industries such as chassis and cabinets, power equipment, steel structures, construction machinery, environmental protection equipment, elevator manufacturing, automotive parts, and sheet metal processing.

Compared to traditional hydraulic plate bending machines, the WSK series uses an electro-hydraulic single servo control system. Through real-time feedback from a grating ruler and proportional servo valve control, it achieves high-precision synchronous operation of the slider, significantly improving bending accuracy and repeatability.
