The 125T 3200mm Hydraulic NC Press Brake offers a nominal force of 125 Tons (1250 kN) and a bending length of 3200mm (10 feet). This combination makes it ideal for processing standard 10ft sheet metals, carbon steel, stainless steel, and aluminum plates across various thicknesses.
Key Highlights:
- Optimal Working Width: 3200mm length easily handles full-size metal sheets.
- Versatile Bending Force: 125-ton capacity accommodates mild steel up to 4mm–6mm thickness (depending on die opening).
- High-Precision NC Control: Powered by the proven Estun E21 controller for accurate backgauge positioning and stroke adjustment.
- Heavy-Duty Welded Frame: Stress-relieved steel frame structure ensuring minimal deformation during high-pressure operation.
2.Smart Control System: Estun E21 NC Controller
At the heart of this press brake’s efficiency is the Estun E21 NC Control Unit. Specially developed for 2-axis press brakes, the E21 system offers an incredible balance between ease of use, stability, and high performance.
Core Features of the Estun E21 Controller:
- 2-Axis Control: Precision control over the X-axis (Backgauge position) and Y-axis (Ram stroke / bending depth).
- Program Memory: Store up to 40 programs, with up to 25 steps per program, significantly reducing setup times for recurring orders.
- Retreat Functionality: Prevents workpiece interference with the backgauge during the bending process.
- One-Key Parameter Backup & Restore: Protects your operational data against accidental loss or corruption.
- Multi-Language Support & Clear Interface: Simple LED display with intuitive button layout for hassle-free operation by both novice and veteran technicians.
3.Structural Design & Premium Components
A great press brake is defined not only by its control system but also by its mechanical and hydraulic integrity. The 125T 3200mm machine features robust engineering designed for long service life.
Key Structural Features:
- Rigid Steel Monoblock Frame: Built with solid steel plates treated with heat tempering to relieve internal stress, ensuring long-term bending accuracy.
- Quick Clamp System: Enables rapid changing of upper punch tools, reducing downtime during product switches.
- Front Support Arms: Heavy-duty front sheet support arms equipped with linear guides for smooth material sliding and positioning.
Rear & Hydraulic System Highlights:
- Synchronized Torsion Bar System: Mechanical torsion bar maintains perfect parallelism between the two cylinders for consistent bending angles.
- Reliable Hydraulic Circuit: Top-grade hydraulic pumps and valves ensure smooth downward/upward motion and low operational noise.
- Motorized Backgauge: High-precision ball screw and linear guide drive mechanism ensure repeatable positioning accuracy (±0.1mm).

5.Main Applications
The 125T 3200mm NC Press Brake is widely utilized across multiple metal processing industries, including:
- HVAC & Ductwork: Bending thin to medium galvanized sheets into ventilation ducts.
- Door & Cabinet Manufacturing: Fabrication of fireproof doors, electrical control boxes, and stainless steel enclosures.
- Automotive & Agricultural Machinery: Manufacturing structural brackets, guards, and paneling.
- General Metal Fabrication Workshops: Perfect for job shops handling diverse sheet metal jobs requiring fast setup and high repeat precision.
6.Why Choose an NC Press Brake Over Manual or Full CNC?
When selecting a press brake, business owners often weigh their options between Manual Hydraulic Press Brakes, NC (Estun E21), and Full Electro-Hydraulic CNC (Delem/DA53T/DA66T) models.
- Compared to Manual Brakes: The NC version automates the X-axis backgauge and Y-axis positioning, dramatically increasing production speed, reducing operator fatigue, and eliminating manual measurement errors.
- Compared to High-End CNC Brakes: The 125T 3200mm NC Press Brake provides 80% of the daily bending functionality at a fraction of the cost. It has a lower initial investment, simpler maintenance, and faster ROI for standard 2D sheet metal bending.

7.Frequently Asked Questions (FAQ)
Q1: What maximum steel thickness can a 125T 3200mm press brake bend?
- A: Over a full 3200mm length, a 125T press brake can comfortably bend up to 4mm mild steel (using a standard V-die opening of $V=32\text{mm}$ or $V=40\text{mm}$). For shorter bending lengths (e.g., 1500mm), it can handle carbon steel up to 6mm–8mm thickness.
Q2: Is the Estun E21 controller easy for operators to learn?
- A: Yes, the Estun E21 system is renowned for its user-friendly interface. Most operators can master basic programming and daily operations within 1–2 hours of training.
Q3: How do I maintain the hydraulic press brake for longevity?
- A:
- Regularly change the hydraulic oil (typically every 2,000 working hours or once a year).
- Keep the guide rails and ball screw clean and well-lubricated.
- Check and tighten hydraulic pipe joints periodically to prevent oil leaks.
- Keep the upper and lower dies clean to avoid surface scoring.
