CNC Electric Servo press brake's Product Overview
The CNC Electric Servo press brake is used to bend metal sheets into required angles and shapes. It is a key machine in sheet metal fabrication.
The machine adopts full electric servo direct drive technology. Servo motors move the ram directly, while the CNC system controls position and speed for stable bending accuracy.
Accurate bending is critical to assembly fit, structural strength, and product consistency. Therefore, it is widely used in industries such as automotive, electronics, electrical cabinets, and HVAC equipment.
CNC Electric Servo press brake's Brake Components
The CNC Electric Servo press brake consists of mechanical structure and control systems.
Mechanical Structure: high-rigidity frame, servo-driven ram system, back gauge system, and bending tooling system.
Control System: CNC control system, electrical control system, and safety protection system.
All systems work together to ensure stable and efficient bending operations.
CNC Electric Servo press brake's Features & Benefits
The servo direct drive system replaces the traditional hydraulic system and significantly reduces energy consumption. For example, a 100-ton press brake consumes about 12 kWh per day under 8 hours of operation, while a hydraulic system may consume around 60 kWh, saving about 80% energy.
The closed-loop servo system with precision sensors provides real-time feedback and dynamic compensation. Positioning accuracy can reach 0.01 mm, ensuring consistent quality even for complex parts.
The machine features a touch control interface with graphical programming and CAD file import. It simplifies operation and reduces production preparation time.
Without a hydraulic system, components such as cylinders, pumps, valves, and oil pipes are eliminated. Only regular lubrication is required for stable operation.

What is the difference between CNC Electric Servo press brake and CNC Hydraulic Press Brake?
| Comparison Item | CNC Electric Servo press brake | CNC Hydraulic Press Brake |
| Drive System | Full electric servo motor direct drive | Electro-hydraulic drive system |
| Power Transmission Efficiency | Servo motors drive the ram through mechanical transmission (ram return speed 200mm/s; working speed 0-20mm/s) | Hydraulic cylinders drive the ram (ram return speed 120mm/s; working speed 10mm/s) |
| Energy Consumption | Very low energy consumption, up to ~80% energy saving | Higher energy consumption due to continuous hydraulic system operation |
| Response Speed | Fast response and quick start/stop | Slower response due to hydraulic oil circulation |
| Bending Accuracy | Very high precision with closed-loop servo control: The bending angle tolerance is within ±0.5° | High precision with electro-hydraulic synchronization: The bending angle tolerance is within ±1° |
| Noise Level | Lower noise during operation | Higher noise from hydraulic system |
| Maintenance Costs | Minimal maintenance cost, no hydraulic oil required, only regular lubrication | Regular maintenance of oil, seals, pumps, and valves: The hydraulic system is easily containminated, making troubleshooting difficult and system cleaning complicated; may also environmental pollution |
| Environmental Impact | Stable operation without affectng by heat | Affected by ambient conditions and heat generated by the hydraulic system, requiring machine warm-up before operation or cooling time after shutdown |
| Trouble Shooting | have fewer components and lower failure rate, thus easier and efficient toubleshooting and maintenance | Require high technical expertise and considerable time |
| Suitable Production | High-precision and energy-efficient manufacturing | Heavy-duty bending and large-tonnage applications |
| Typical Industries | Electronics, precision parts, cabinets, HVAC | General sheet metal fabrication, construction machinery, heavy industries |
CNC Electric Servo press brake's Role in the Production Line
In the sheet metal production process, the Heavy Duty Laser Cutting Machine first performs sheet cutting. The CNC Electric Servo press brake then bends the cut sheets into the required structural shapes.
For some products, the bent parts are further processed by the CNC Servo Press for punching or forming operations.
CNC Electric Servo press brake plays a key role in shaping sheet metal parts and ensuring dimensional accuracy in the production line.
