The WyBend NC Series is a hydraulic press brake with NC control, available in 5 configurations, from the 40/2500 (400 kN force, 2500 mm length) up to the 125/4000 (1250 kN force, 4000 mm length), designed for metalworking workshops and steel-structure plants that need high productivity and operational simplicity. With an Estun NC system with 80 stored programs, ±1° angle accuracy, torsion-bar synchronization and a Bosch Rexroth / Parker Hannifin hydraulic system at 32 MPa, this press brake offers industrial reliability at an affordable investment cost compared with full-servo CNC systems.
The torsion-bar synchronization of the WyBend NC Series press brake ensures the parallelism of the upper beam over the entire working length through a high-reliability mechanical mechanism, with no dependence on the complex electro-hydraulic systems of advanced CNC press brakes, reducing maintenance costs and increasing availability in continuous production.
Key advantages of the WyBend NC Series press brake
• Estun NC system: 80 stored programs, ±1° angle accuracy. The Estun NC panel of the press brake manages the bending programs with storage capacity for 80 programs, a large display, ±1° angle accuracy and automatic calculation of the bending depth according to material and thickness, with multi-language support for European operators.
• Torsion-bar synchronization: guaranteed parallelism over the entire length. The torsion-bar synchronization mechanism maintains perfect parallelism of the upper beam relative to the lower table over the entire working length of 2500–4000 mm, with no need for a complex electro-hydraulic deflection-compensation system.
• Bosch Rexroth / Parker Hannifin hydraulic system: 32 MPa, 45,000-hour oil life. The premium Bosch Rexroth Germany and Parker Hannifin USA hydraulic components ensure constant pressure of 32 MPa, with a hydraulic-oil life of 45,000 hours and linear guides for precise piston movement.
• Precise X+R back gauge:±0.1 mm accuracy. The precise back gauge with the X axis (distance from the bending axis) and the R axis (back-gauge height) positions the material with ±0.1 mm accuracy, with a step-back function for complex bending sequences with multiple steps.
• Tool system 40–150 mm height with quick adjustment: the tool system with standard heights of 40–150 mm and quick changeover of punches and dies reduces setup times when changing bending profiles, with compatibility with standard European Wila tools.
• IEC 61496 safety curtains: detection at 12 mm. The light curtains with detection at 12 mm, a height of 450–1000 mm and IEC 61496 compliance protect the operator and immediately stop the press brake at any entry into the danger zone.
• 5 models: force 400–1250 kN, length 2500–4000 mm. The WyBend NC range covers any standard sheet-bending requirement in metalworking workshops, from the small 40-tonne press brakes for light profiles to the 125-tonne press brakes for thick sheets in a 4-meter format.

Materials compatible with the WyBend NC Series press brake
Carbon steel and structural steel: the WyBend NC Series press brake processes S235–S355 carbon steel with thicknesses from 0.5 mm up to 8–12 mm depending on the chosen model and bending length, with programmable angles from 0° to 160° and a repeatability of ±1° across the entire production run.
Stainless steel: stainless steel requires greater bending force than soft carbon steel; for the same thicknesses, selecting a model with a higher nominal force is recommended. The Wila tool system with punch and die made of tool steel ensures contact-surface quality on stainless steel with no scratches or marks on the finished surface.
Aluminum and non-ferrous sheets: aluminum and non-ferrous alloys are processed with dedicated tools and adjusted angles to compensate for the greater springback compared with carbon steel, parameters programmable directly in the Estun NC system for each material in the profile library.
Applications and industries for the WyBend NC Series press brake
The WyBend NC Series press brake is intended for metalworking workshops, electrical-cabinet plants, producers of steel structures and service workshops that perform standard bends on common sheet-metal formats, where the Estun NC system ensures high productivity without the complexity and maintenance cost of advanced CNC systems.
Producers of metal furniture, shelving and storage systems use the WyBend NC Series press brake for repetitive bends on constant profiles: 80 stored programs allow fast switching between different profiles with no manual re-entry of parameters, with the X+R back gauge ensuring positioning accuracy over long runs.
Automotive service workshops and producers of components for the construction industry use the 100/3200 and 125/4000 models of the WyBend NC press brake for bends on thick 6–12 mm sheets over lengths of 3200–4000 mm, where the 100–125 tonne force and the torsion-bar synchronization ensure angle uniformity over the entire bending length.
How the WyBend NC Series press brake works
1. NC programming. The operator enters or recalls the bending program on the Estun NC panel: material, thickness, angle and number of steps are set digitally, with automatic calculation of the bending depth to compensate for springback.
2. X+R back-gauge setting: the back gauge automatically positions itself at the programmed X distance with ±0.1 mm accuracy and at the correct R height for the first bend in the sequence.
3. Sheet feeding and bending: the sheet is fed in until it contacts the back gauge; the operator activates the cycle via the pedal or start button; the upper beam descends hydraulically at rapid speed, then switches to the slow bending speed as it approaches the sheet.
4. Torsion-bar synchronization: the torsion bar maintains perfect parallelism of the upper beam relative to the table over the entire 2500–4000 mm length during the bend, ensuring a uniform angle across the entire part width.
5. Lifting and back-gauge advance: the upper beam rises at rapid speed; the back gauge automatically advances to the position for the next bend in the sequence; the cycle repeats for the programmed number of steps.
Frequently asked questions about the WyBend NC Series press brake
What is the difference between NC and CNC control on a press brake?
The NC control of the WyBend NC Series press brake manages the X (back gauge) and R (back-gauge height) axes through numerical programs with ±0.1 mm accuracy, with automatic calculation of the bending depth. Advanced CNC control (the WyBend C, E, H series) adds control of the Y axis (the position of the hydraulic cylinders), automatic deflection compensation, servo systems with ±0.01 mm accuracy and advanced 3D programming functions. NC is the optimal solution for repetitive production of standard profiles; CNC is needed for complex parts with tight tolerances over long bending sequences.
Can the WyBend NC Series press brake use standard European tools?
Yes. The WyBend NC Series press brake is compatible with standard European tools with heights of 40–150 mm, including the Wila tools mentioned in the specifications. Compatibility with standard European tool systems reduces tooling costs and allows the use of the workshop's existing tools. UZINEX provides consulting to verify compatibility with the customer's specific tools.
