Traditional large-tonnage electric press brakes often face a core challenge during processing: their ballscrew drive guidance typically relies on sliding guides. However, when the press brake is in operation, the side-frame throat deforms under load – and the greater the bending force, the greater the deformation. This deformation leads to a misalignment between the sliding guide direction and the load direction of the ballscrew drive, subjecting the transmission screw to additional stress. As a result, the screw may bend under load and, in severe cases, even fracture. This not only affects the normal operation of the press brake but also poses a major challenge to machining accuracy and equipment stability.

To address this industry challenge, the Deratech R&D team, drawing on profound technological expertise, has innovatively launched a new generation of large-tonnage CNC servo electric press brake equipped with an independent ball screw drive guiding system.

The core advantage of this device lies in its ability to effectively prevent deformation of the side-plate throat from interfering with the screw drive, essentially building a solid “barrier” for the screw transmission system. In actual operation, regardless of how the side-plate throat deforms under stress, the screw consistently maintains precise and stable transmission, ensuring controllable accuracy for every bending process.

After more than a year of rigorous use and testing at customer sites, this press brake has successfully entered mass production, with its reliability and stability thoroughly validated. For example, the recently delivered EPP-160/3200 large-tonnage CNC Servo Electric Press Brake to a customer in Dalian, Liaoning Province, equipped with the VP88 CNC system from Switzerland's Cybelec, fully meets production requirements with the following configurations:

• Two-axis servo follower support device: accurately supports sheet material during bending, reducing labor intensity while further enhancing processing accuracy and efficiency;
• DSP safety light curtain: provides all-around protection for operators, ensuring a worry-free production process.
• Six-axis Backgauge System
1. Improved machining accuracy:
   The six-axis backgauge can adjust the stop position to the optimal setting according to the requirements of the workpiece, thereby enhancing machining precision.
2. Wider applicability:
   The six-axis backgauge can accommodate plates of different specifications and shapes, making it suitable for processing various complex workpieces such as chassis, electronic and digital product housings, and other high-precision, high-difficulty components.
3. Increased production efficiency:
   With its high accuracy and flexibility, the six-axis backgauge reduces scrap rates caused by positioning errors, shortens adjustment times, and improves overall production efficiency.
4. Enhanced stability:
   The six-axis backgauge is designed with stability in mind; even during high-speed operation, it can maintain precise positioning while minimizing vibration and deviation.
• VP88 CNC System:
  Provides an intelligent and user-friendly control interface, enabling operators to easily set bending parameters and achieve precise execution of complex bending processes.

Deratech's latest technological breakthrough has undoubtedly set a new benchmark in the field of large-tonnage CNC servo electric press brake. It not only represents Deratech's outstanding strength in technological research and development, but also demonstrates unwavering commitment to quality and innovation. The promotion and application of this new generation of large-tonnage CNC servo electric press brakes will deliver more efficient, more precise, and safer production solutions for customers in sheet metal processing and related industries.
