The KAVDO Torsion Bar Press Brake uses a mechanical torsion bar to synchronize the left and right hydraulic cylinders, delivering reliable, repeatable bending without complex electronics — at a significantly lower cost.
- Torsion bar ensures ram parallelism without electronics
- Stress-relieved welded frame for long-term rigidity
- NC or full CNC controller options available
- Low maintenance — fewer components to service
Why This Machine
Key Advantages
A perfect balance of performance, simplicity and value — engineered for workshops that need reliable bending without unnecessary complexity.
Exceptional Value
Torsion bar synchronization eliminates expensive servo valves and electronic encoders, delivering 30–40% cost savings over electro-hydraulic models — without sacrificing day-to-day bending quality.
±0.02 mm Repeatability
Precision-ground ram guides and a rigid torsion bar linkage maintain consistent positioning accuracy cycle after cycle, meeting the demands of most general fabrication work.
Simple & Reliable
The mechanical torsion bar has no electronic sensors, no servo valves and no calibration drift. It delivers maintenance-free synchronization that works reliably for decades.
Easy Operation
Intuitive E21 or Delem NC/CNC controllers with clear numeric displays and straightforward programming make the machine easy to learn — operators are productive within hours, not days.
Low Running Cost
Fewer electronic components mean lower spare parts costs and simpler troubleshooting. The robust hydraulic system is designed for long service intervals and minimal downtime.
Safe & CE Certified
Equipped with rear safety fence, emergency stop system and optional light curtain protection. CE-certified design ensures compliance with international safety standards.
