What is a fully servo press brake?
A fully servo press brake is a high-precision and high-efficiency CNC bending machine driven by full servo motors. Compared with traditional hydraulic or hybrid-driven press brakes, it has significant advantages in control accuracy, energy saving, and response speed.
1.Core features of the all-servo bending machine:
(1) All-servo motor drive
Slide (Y-axis): Servo motor + ball screw/gear rack drive, replacing traditional hydraulic cylinders.
Back gauge (X/R/Z-axis): Servo motor control, providing more precise positioning.
No hydraulic system: Completely eliminating issues of hydraulic oil contamination, leakage and energy consumption.
(2) High-precision control
Angle accuracy: Within ±0.1° (compared to ±0.5° for traditional hydraulic machines).
Repeat positioning accuracy: ±0.01mm (far exceeding the ±0.05mm of hydraulic machines).
Dynamic compensation: Real-time adjustment of the slide position to reduce springback error.
(3) Energy-efficient and high-performance
Energy consumption reduced by over 70%: Only consumes power during operation, no continuous running of hydraulic pumps.
Faster speed: No-load speed can reach 500mm/s, reducing the bending cycle by 30%.
(4) Intelligent functions
Adaptive control: Automatically adjusts bending parameters (such as pressure and speed).
Remote monitoring: Supports IoT data collection and fault early warning.
2.The core structure of the fully servo bending machine
(1) Servo motor + ball screw / gear rack
Replace the hydraulic cylinder and directly drive the slider to move up and down, with faster response.
Use high-precision encoders to achieve closed-loop control.
(2) CNC system
High-end brands: Delem DA-69T, Cybelec DNC880.
Support 3D simulation, automatic calculation of bending parameters.
(3) Deflection compensation system
Mechanical or electric compensation to ensure uniform bending of long workpieces.(4) Mold quick-change system
Some models support automatic mold change, improving the efficiency of multi-variety production.
