CNC Torsion Bar Press Brake (CybTouch CNC)

Long Version (for tender / quotation, technical brochure, match your welding paragraph)

This CNC torsion bar press brake is equipped with CybTouch CNC controller, precision ball screw, linear guide rails, quick clamping system and proportional hydraulic valve, delivering stable, high-precision and repeatable bending performance for sheet metal fabrication.

The CybTouch touchscreen CNC features intuitive graphical programming, 2D profile drawing, automatic bend sequence calculation, angle compensation and crowning management. It supports multi-language operation, offline programming and USB data export, greatly simplifying setup for complex bending jobs and shortening operator learning time.

Precision ball screws and linear guide rails drive the backgauge for smooth, low-wear movement, securing excellent repeat positioning accuracy and consistent workpiece dimensions batch by batch. The quick clamping system enables fast tool loading and unloading, drastically reducing mold change downtime and boosting production efficiency.

Core Highlight: Proportional Hydraulic Valve

Different from simple on-off hydraulic valves, the high-performance proportional hydraulic valve realizes stepless, closed-loop continuous regulation of hydraulic pressure and flow, perfectly synchronised with the CybTouch CNC control signals.

1. Smooth speed transition: It achieves seamless switching among fast approach, slow bending and return stroke without hydraulic impact. Vibration and noise are obviously reduced, protecting the machine frame and prolonging service life.
2. Stable bending angle accuracy: The valve automatically adjusts hydraulic output in real time according to material thickness, tensile strength and load variation. It compensates frame deflection dynamically, ensuring uniform bending angles even for long workpieces.
3. Flexible pressure & speed profiling: Bending pressure and ram speed can be independently programmed for each bending step, suitable for thin sheets, thick plates, stainless steel, aluminium and high-strength steel.
4. Fast response & high stability: Closed-loop feedback ensures rapid and precise hydraulic response. It avoids pressure fluctuation during continuous mass production and minimizes cumulative bending errors.
5. Lower maintenance cost: Gentle, impact-free hydraulic movement reduces shock to seals, pipelines and hydraulic components, lowering oil leakage risk and extending the service life of the whole hydraulic system.

Combined with our rigid stress-relieved welded frame (full penetration welds, 100% NDT inspection), this torsion bar press brake maintains outstanding long-term precision stability. It is widely applied in cabinets, machinery frames, construction metal parts and general sheet metal workshops.

Short Version (for product header / catalogue caption)

Our CNC torsion bar press brake is fitted with Swiss CybTouch touch CNC system, precision ball screw, linear guide rails, quick clamps and proportional hydraulic valve. The proportional hydraulic valve supports stepless closed-loop control of pressure and flow. It delivers smooth, impact-free ram movement, automatically compensates for material and load differences, keeps consistent bending angles in mass production, and reduces vibration and hydraulic shock. Matched with CybTouch’s advanced bending algorithm, the machine achieves reliable, high-precision bending for various sheet metals.
