Amada HDS-5020NT CNC Press Brake

The Amada HDS-5020NT is a 500-ton, 6.2-meter hydraulic synchronous press brake designed for heavy-duty structural bending in industries including shipbuilding, construction equipment fabrication, agricultural machinery manufacturing, power generation infrastructure, and large-format architectural metalwork. At 500 metric tons of press capacity across a 6,200 mm bed length, the HDS-5020NT occupies the upper range of production press brakes — machines built to form thick structural plate, heavy-gauge stainless and aluminum sections, and large-format enclosures that smaller brakes cannot accommodate by virtue of either tonnage or bed length.

The HDS (Heavy Duty Synchronous) designation describes Amada's approach to hydraulic synchronization on large-frame brakes: dual hydraulic cylinders at each ram-end are electronically synchronized via the AMNC 3i control to maintain ram parallelism within tight tolerances across the full 6,200 mm bed during press operations. This synchronization is critical at heavy tonnage because uneven tool loading on a long bed creates differential ram deflection that results in angular variation across the part length — a problem that is manageable on small brakes but mechanically significant at 500 tons over six meters. The NT (New Technology) designation indicates the current-generation AMNC 3i control platform with updated software features versus earlier HDS-series machines.

The HDS-5020NT's 6,200 mm bed length accepts correspondingly long tooling sections, enabling one-shot bending of structural parts that would require repositioning and reindexing on shorter machines. For shipbuilding and construction equipment applications where parts can be 4–5 meters long, this length capacity is a fundamental production requirement rather than a convenience feature. The machine's back gauge is designed for large-format part handling with extended gauge reach and sufficient Z-axis travel to position the back edge of large plate workpieces precisely.

Amada's AMNC 3i CNC control provides bend sequence programming, automatic crowning compensation for bed deflection under load, ram depth control calibrated to material springback, and connectivity to VPSS 3i offline programming. The auto-crowning system is particularly important on a 6,200 mm bed: without active crowning compensation, the natural deflection of the bed and ram under 500 tons of press force produces a barrel-shaped bend profile across long parts. The AMNC 3i continuously adjusts the crowning system during pressing to maintain a straight bend line from end to end on the workpiece.
