This electro-hydraulic synchronous CNC press brake is designed for professional sheet metal bending operations where consistent accuracy,
structural rigidity, and long-term stability are required.

The machine uses electro-hydraulic synchronization to control the Y1 and Y2 cylinders precisely, helping maintain slide parallelism and
achieve repeatable bending results across the full working length.

To improve accuracy under load, mechanical compensation is applied to reduce deflection and deformation impact during bending,
supporting stable angle control in continuous production.

The backgauge system is driven by a digital AC servo motor with precision ball screw transmission and linear guide rails,
providing smooth positioning and reliable repeatability for batch processing.

FAQ

All specifications are provided by our engineering team based on actual machine configurations and production experience.

We offer a complete range of CNC press brakes for sheet metal bending, including electro-hydraulic synchronous press brakes, torsion bar press brakes, tandem (dual-machine) press brakes, and customized special-purpose press brakes.
Our main series include PSB, PSM, PSN, PSD, PSA, and PSS, covering light-duty to heavy-duty industrial applications.

Press brake tonnage depends on material type, material thickness, bending length, and die opening.
As a general reference:

Tonnage ≈ (650 × S² × L) / V

Where:

  • S = material thickness (mm)

  • L = bending length (m)

  • V = die opening (mm)

Our engineers can calculate the exact tonnage and recommend the most suitable model based on your actual production needs.

Electro-hydraulic synchronous press brakes use servo valves and closed-loop control systems to achieve higher accuracy, better repeatability, and stable synchronization, making them suitable for precision and heavy-duty bending.
