Electric Press Brake Bending Machine is a kind of metal plate bending equipment with servo motor drive as the core power source, replacing the traditional hydraulic or pneumatic drive method. It is widely used in the metal processing field (such as automotive parts, medical equipment, electronic equipment and other precision bending scenarios) by virtue of high precision, high efficiency, energy saving and environmental protection.

Main Structures
Structural Framework: The Electric Press Brake Bending Machine's robust frame serves as the foundation, maintaining rigidity and stability throughout the bending process.
Precision Drive System: Comprising servo motors (primary power source) along with ball screws or linear guides (motion transmission components), this system converts rotational motion into precise linear movement of the ram, ensuring accurate positioning.
Tooling Setup: The bending toolset includes an upper die (typically V-shaped or custom-designed) and a corresponding lower die with matching grooves. These interchangeable dies determine the final bend angle and profile of the metal sheet.
Intelligent Control System: Equipped with a high-precision PLC or dedicated CNC controller (e.g., DELEM, CYBELEC), the system allows pre-setting of bending parameters (angle, speed, pressure, etc.) and supports multi-step program storage for automated operation.
Supporting Components: Additional features include a back gauge (for sheet positioning), deflection compensation (to counteract frame deformation and maintain accuracy), and integrated safety mechanisms for operator protection.
Applications
With the features of high precision, environmental protection and high efficiency, the pure electric bending machine is widely used in the fields of automobile and parts (such as battery shell, brake pad steel back), precision electronics (such as equipment shell, metal centre frame), medical equipment (such as instrument shell, bracket), kitchen and bathroom home appliances (such as stainless steel sink, air conditioner frame), etc., and it is especially suitable for the scenarios that have high requirements on bending precision and cleanliness.

Our Service
1. What are the key benefits of pure electric bending machines compared to hydraulic presses?
Pure electric models offer superior precision (±0.01mm), significantly lower energy consumption (30%-60% reduction), no risk of hydraulic oil leaks, and minimal maintenance requirements.
2. What is the maximum plate thickness that can be bent?
Standard models handle sheets ranging from 0.3mm to 12mm, depending on machine tonnage. However, ultra-thick materials may still require hydraulic presses for optimal performance.
3. Can long-term accuracy be sustained?
Yes, thanks to servo-driven control and real-time deflection compensation, consistent precision is maintained with periodic calibration.
4. How noisy is the operation?
Noise levels remain low (approximately 60-70 dB), making these machines suitable for cleanroom and noise-sensitive environments.
5. Is the operation complex?
Not at all. The user-friendly CNC interface allows operators to become proficient within a week of training.
6. Are there challenges with high-tonnage models?
Earlier designs faced issues with frame deformation under heavy loads, but modern solutions-such as independent guide mechanisms-have effectively resolved these accuracy concerns.
