1. Features and Capabilities:
■ Modern machine frame design ensures an optimal installation footprint.
■ Compact build with high operational safety, resistant to external influences.
■ Reinforced, heavy-duty sidewalls for added structural rigidity.
■ Maintenance-free, dual ram guiding system, independently controlled for Y1 and Y2 axes.
■ Advanced hydraulic system featuring a proportional multi-valve configuration and pressure management, equipped with an energy-efficient STOP&GO function during operation.
■ High-precision, dual active ram position measurement system ensuring top bending accuracy. The system includes a minimum of two independent, highly accurate linear encoders installed on mounts decoupled from the frame. Ram positioning accuracy is +/- 0.01 mm. Provides full electro-hydraulic frame synchronization (Y1, Y2).
■ Ram parallelism to the bending axis is maintained by a double roller guide on both sides of the internal frame section, supplemented by crosswise ram reinforcements.
■ Cylinders and pistons are made from high-strength steel with chrome-plated piston surfaces.
■ The machine and its accessories are intuitive to operate and designed for easy maintenance.
■ Provisions are made for future upgrades with new technical innovations.
■ All digital axis drives are powered by premium, maintenance-free AC servomotors.
■ The rear backgauge utilizes dual linear guides for precise bilateral movement.
■ An extensive and versatile tooling portfolio enables flexible processing of a wide range of workpieces.
■ The design and construction comply with EU health and safety directives in line with the CE mark. The machine is CE-certified and built according to Directive 2006/42/EC.

3.6 5-Axis CNC Backgauge System: X-ΔX-R-Z1-Z2
X axis: Parallel movement of the backgauge beam
ΔX axis: Adjustable backgauge finger for angled (skew) bends. Adjustment range +/- 175 mm (total 350 mm).
R axis: Vertical adjustment of the backgauge beam
Z1, Z2 axes: Automatic lateral travel of backgauge fingers along the beam.
All axes are powered by AC servo drives.
Two backgauge fingers on the beam with integrated sheet support feature.
All axes are CNC controlled by the DNC system.
