SHENCHONG 300t 5100mm CNC Press Brake WEK 4+1 axis ESA S630 is a medium to large-sized hydraulic CNC bending machine for sheet metal. Its core features can be summarized as follows: 300-ton rated bending force + 5100mm ultra-long bending length + electro-hydraulic synchronous control + Y1/Y2 independent control + X/R dual-axis back gauge + ESA S630 graphic CNC system + CNC mechanical compensation.
This configuration is particularly suitable for production scenarios requiring long-dimension, high-tonnage bending, such as steel structures, engineering machinery, automobile manufacturing, pressure vessels, ventilation equipment, chassis and cabinets, heavy sheet metal, construction machinery, and large metal structural components.

The 300TX5100mm is not an ordinary small sheet metal press brake bending machine, but a CNC bending machine clearly geared towards processing long, medium-to-heavy sheet metal.
Where it is located:
- 300 tons: Represents the maximum nominal bending force of the machine, approximately 3000kN
- 5100mm: Represents the effective worktable length, approximately 5.1 meters
- WEK: Machine series
- 4+1 axes: Refers to Y1, Y2, X, R + V
- ESA S630: Italian ESA series 2D graphical CNC system
- Y1/Y2: Independent synchronous control of left and right hydraulic cylinders
- X-axis: Back gauge forward and backward movement
- R-axis: Back gauge up and down movement
- V-axis: Worktable mechanical deflection compensation
The ESA S630 itself is positioned as a 4-axis graphical CNC system, with standard configuration supporting Y1/Y2/X/R, and features automatic bending force calculation, compensation calculation, die library, angle correction, and other functions.

SHENCHONG 300t 5100mm CNC Press Brake is specifically designed for processing large, medium-thick plates and long metal structural parts. The 300-ton high pressure provides ample bending capacity, while the 5100mm extra-long working length meets the processing needs of large sheet metal, reducing repeated clamping, flipping, and secondary positioning of large workpieces, making large sheet metal processing more efficient.
The equipment adopts dual-cylinder synchronous control technology, achieving synchronous left and right movement of the slider through Y1/Y2. X+R CNC backgauge provides precise positioning. the CNC V-axis compensation system compensates for the deflection of the worktable generated during long-length bending, resulting in a more stable and uniform bending effect for the workpiece in different positions.
Equipped with the ESA S630 CNC system, this system transforms complex bending processes into standardized digital programs through graphical programming, workpiece and mold management, bending force calculation, compensation calculation, and angle correction. It is suitable for industries such as engineering machinery, steel structures, vehicle manufacturing, power equipment, environmental protection equipment, and large sheet metal manufacturing.
