The WyBend E Series is a high-precision CNC press brake with individual servo motors on each axis, a linear encoder with 0.1 micron resolution and an automatic tool-clamping system, available in 6 configurations — from the E 40 (400 kN, 1500 mm) up to the E 220 (2200 kN, 4000 mm) — designed for producers of metal parts with extremely tight tolerances, the precision automotive industry, aerospace and producers of medical equipment. With a Renishaw / Heidenhain linear encoder with ±0.005 mm accuracy, a 6-axis back gauge at ±0.02 mm and the option of full KUKA / ABB / Fanuc robotic integration with automatic changeover of 312 tools, this high-precision CNC press brake represents the technological pinnacle of the WyBend family.
The architectural difference from the WyBend C series with a hydraulic servo is fundamental: the WyBend E Series high-precision CNC press brake uses individual electric servo motors for each axis instead of hydraulic drive, eliminating the variabilities introduced by the hydraulic oil's viscosity changing with temperature, by cylinder-seal wear and by fluid compressibility — with a faster response and 2× better accuracy than electro-hydraulic systems of a similar level.
Key advantages of the WyBend E Series high-precision CNC press brake
• Renishaw / Heidenhain linear encoder — 0.1 micron resolution, ±0.005 mm accuracy — the WyBend E Series high-precision CNC press brake uses Renishaw or Heidenhain linear encoders with 0.1 micron resolution and ±0.005 mm position-feedback accuracy — 2× more precise than the rotary encoders of standard hydraulic systems, with high resistance to electromagnetic interference in industrial environments.
• Individual Yaskawa / HIWIN / FANUC servo motors — ±0.01 mm, 200 mm/s speed — the individual servo motors on each axis ensure independent control of each point of the stroke, with ±0.01 mm accuracy and a speed of up to 200 mm/s, with no dependence on hydraulic-oil viscosity or ambient temperature that affect electro-hydraulic systems.
• 6-axis CNC back gauge — ±0.02 mm accuracy, 500 mm/s speed — the back gauge with 6 CNC-controlled axes and a travel speed of 500 mm/s ensures fast, precise positioning of the material with ±0.02 mm accuracy, with support for 1–3 mm retract strokes to release the sheet after bending.
• Automatic tool-clamping system — 10× faster changeover than manual — the automatic tool-clamping system with a clamping speed of 10 mm/s at 500 mm/s reduces tool-changeover time by a factor of 10 compared with manual changeover, with individual clamping and release of each tool for maximum flexibility in configuring complex profiles.
• Optional KUKA / ABB / Fanuc robotic integration — 312 automatic tools — the option of full robotic automation with automatic changeover from a library of 312 tools and robotic accuracy of ±0.05 mm turns the WyBend E Series high-precision CNC press brake into an automatic production cell capable of producing small batches with no manual intervention.
• Standard Euro and Promecam tool interface — maximum compatibility — the TPA / Fibertool tool interface compatible with standard Euro and Promecam tools allows the use of the workshop's existing tools and the purchase of specialized tools from any European supplier.
• 6 models — force 400–2200 kN, length 1500–4000 mm — the WyBend E range covers the widest interval in the WyBend family, with the E 220 model at 2200 kN and 4000 mm representing the largest high-precision CNC press brake in the UZINEX portfolio for this series.

WyBend E versus WyBend C — electric servo versus hydraulic servo
The WyBend C Series with a Bosch Rexroth/Yaskawa hydraulic servo offers ±0.01 mm accuracy — excellent for the vast majority of industrial precision applications. The WyBend E Series high-precision CNC press brake with individual electric servo motors and a Renishaw linear encoder adds: ±0.005 mm feedback accuracy (2× finer), the elimination of the variabilities introduced by the hydraulic system (viscosity, temperature, seal wear), a back-gauge speed of 500 mm/s versus the typical 200–300 mm/s of hydraulic systems, and the option of full robotic automation with 312 automatic tools.
The WyBend E is the choice when: the part tolerances require accuracy below ±0.01 mm, production includes small batches with many different tool types where automatic clamping significantly reduces setup times, or when full robotization is the objective for eliminating bending labor.
Applications and industries for the WyBend E Series high-precision CNC press brake
The WyBend E Series high-precision CNC press brake is intended for producers in industries with the strictest bending-tolerance requirements — precision automotive components (bodywork, safety structures), the aerospace industry (special-alloy profiles with tolerances below ±0.1°), medical equipment and precision instruments where every tenth of a degree counts for the correct functioning of the final product.
High-level subcontracting workshops that produce parts for the automotive and aerospace industries use the WyBend E Series high-precision CNC press brake with the KUKA/ABB robotic option for the automatic production of small and medium batches with a wide variety of tools — the robot automatically changes the tools from the library of 312, the operator only supervises the process and feeds the material.
Producers of precision electronic equipment and housings for measuring instruments use the E 40 and E 80 models of the WyBend E Series high-precision CNC press brake for precision bends on thin 0.5–3 mm sheets of stainless steel, aluminum and special alloys, where the angular tolerance of ±0.1° and part-to-part repeatability are mandatory.
How the WyBend E Series high-precision CNC press brake works
1. CNC programming or offline import — the program is created on the Delem DA-69T or imported from CAD/CAM; the system automatically calculates the parameters for each bend with springback compensation specific to the material and thickness.
2. Automatic tool changeover — the automatic clamping system configures the programmed tool sequence at a speed 10× faster than manual changeover; optionally, the robot selects the tools from the library of 312 and mounts them with no human intervention.
3. 6-axis back-gauge positioning at 500 mm/s — the back gauge with 6 axes positions at the programmed coordinates with ±0.02 mm accuracy at the maximum speed of 500 mm/s, reducing idle times between bends compared with slower systems.
4. Bending with ±0.005 mm linear-encoder feedback — the individual servo motors lower the beam; the Renishaw/Heidenhain linear encoders measure the position with 0.1 micron resolution and correct any deviation from the programmed path in real time.
5. Laser angle check and correction — the laser system checks the actual angle and automatically updates the springback parameter for the following parts, ensuring uniformity across the entire production run.
6. Optional robotization — in the configuration with a KUKA/ABB/Fanuc robot, the robot picks up the part, positions it, triggers the bend and unloads it automatically, with the high-precision CNC press brake operating fully automatically on programmed batches.
Frequently asked questions about the WyBend E Series high-precision CNC press brake
Why are linear encoders superior to rotary encoders on a press brake?
Rotary encoders measure the motor rotation and calculate the beam position through the transmission's kinematic ratio — accumulating errors from transmission backlash, shaft elasticity and coupling slippage. The Renishaw/Heidenhain linear encoders on the WyBend E Series high-precision CNC press brake measure the position of the upper beam relative to the frame directly, with no mechanical intermediaries and no accumulation of transmission errors. The result is real position feedback at ±0.005 mm, versus the ±0.02–0.05 mm typical of rotary encoders on the same equipment class.
Can the WyBend E Series press brake operate fully automatically with the integrated robot?
Yes — in the configuration with a KUKA, ABB or Fanuc robot, the WyBend E Series high-precision CNC press brake can operate fully automatically for programmed batches: the robot feeds the sheet, positions it against the back gauge, triggers the bending cycle, repositions the part for the following bends and unloads the finished part. The automatic changeover of 312 tools allows the automatic production of parts with complex sequences of different tools with no manual intervention. UZINEX provides consulting for sizing the robotic cell according to the customer's production requirements.
What is the concrete difference between individual electric servo motors and a hydraulic servo?
The hydraulic servo (WyBend C Series) drives the cylinders with pressurized oil controlled through proportional servo valves — the system depends on the oil viscosity (affected by ambient temperature and running time), the seal tightness (degradation over time) and the compressibility of the hydraulic fluid. The individual electric servo motors of the WyBend E Series high-precision CNC press brake drive each axis directly through an electric motor with a linear encoder — with no intermediate medium, no thermal variabilities and no comparable wear. The practical advantages: 2× finer feedback accuracy (±0.005 mm vs ±0.01 mm), a back-gauge speed of 500 mm/s vs 200–300 mm/s, lower energy consumption (electricity consumed in proportion to the load), and increased reliability in continuous 24/7 production.
For what volume and type of production does the investment in the WyBend E over the WyBend C pay off?
The WyBend E Series high-precision CNC press brake justifies the additional investment over the C Series when: the required angular tolerances are below ±0.1° (premium automotive, aerospace, medical), the volume includes dozens of small batches per month with many different tool types — automatic clamping significantly reduces tool-changeover setup times, or when full robotic automation with KUKA/ABB/Fanuc is planned for production over 2–3 shifts with no labor. For standard production in a metal workshop with high volume and a small profile mix, the WyBend C Series offers the optimal precision/cost ratio. UZINEX provides consulting for a concrete ROI analysis based on the customer's specific production.
