Overview
The LVD Axiobend 6400/250 is one of LVD's largest-format hydraulic CNC press brakes, combining 6,400 mm of working length with 2,500 kN (250 tonnes) of bending force. Designed for fabricators who regularly produce very wide sheet metal panels, structural components, and large formed sections, the Axiobend 6400/250 addresses the requirements of industries including shipbuilding, wind energy, heavy construction, and large-format industrial equipment manufacturing. Few competitors offer this combination of bed length and manageable tonnage in a single machine.
The Axiobend series features LVD's advanced hydraulic synchronisation system, which maintains precise beam parallelism across the full 6.4-metre span under both symmetric and asymmetric loading conditions. This is particularly critical on very long machines, where even small differential forces can cause angular variation from one end of a bend to the other. Active hydraulic crowning is standard, with the CNC automatically calculating and applying the correct crown profile based on tooling and material inputs.
LVD equips the Axiobend 6400/250 with the TOUCH-B 15 CNC control, an enlarged touchscreen variant designed for easy operation with gloves on large-machine production floors. CADMAN-B offline programming software enables program creation, bend simulation, and production scheduling entirely off the machine. The back gauge on this model is extended to cover the full working length and supports multiple reference points to manage the complexity of very wide parts.
The Axiobend 6400/250 is supported by LVD's global service network, a practical consideration given the machine's scale and the downtime cost of an unplanned stoppage. Installation requires detailed site preparation including reinforced flooring, crane access, and adequate ceiling height. For fabricators whose work demands this capability, the Axiobend delivers a rare combination of very long working length with LVD's proven control and adaptive bending technology.

Frequently Asked Questions
01
The Axiobend 6400/250 uses servo-proportional hydraulic valves on both main cylinders, monitored by position encoders at each end of the beam. The CNC synchronisation controller continuously compares encoder feedback and adjusts valve flow to maintain parallel beam travel within fractions of a millimetre, even under asymmetric tool loading or part weight.
02
At 250 tonnes capacity over 6,400 mm, the working tonnage per metre is approximately 39 tonnes/metre. This limits mild steel bending to around 6–8 mm thick at full length. For thicker material, the bed can be loaded over a shorter central section to apply full tonnage — the CNC calculates safe operating limits based on tool positions and material data.
03
LVD does offer tandem press brake configurations using synchronised pairs of PPEB or Axiobend machines for extreme working lengths. However, the 6400/250 is a single-machine configuration. For lengths beyond 6,400 mm, LVD's engineering team should be consulted about tandem synchronisation solutions.
