Amada HGB 50-20

The Amada HGB 50-20 is a compact CNC press brake in Amada's HGB series — a hydraulic bending platform designed for small to medium fabrication shops that need a capable, reliable CNC press brake without the cost or complexity of Amada's servo-electric HFE series or heavy-tonnage HG line. The designation 50-20 indicates 50 metric tons press force and 2,000 mm (78.7 in) bending length, placing the HGB 50-20 in the segment between compact 30-ton shop brakes and full-sized 80–100 ton production machines.

The HGB series is built around a conventional synchronized electro-hydraulic drive with direct-measuring linear encoders for Y-axis feedback. This is established technology that has proven reliable across hundreds of thousands of press brake installations worldwide. The advantage is cost predictability — hydraulic cylinders, pump assemblies, and hydraulic circuits have well-understood maintenance intervals and parts availability. Amada's hydraulic engineering is solid, and the HGB platform benefits from decades of iterative improvement on the fundamental architecture.

Y-axis accuracy on the HGB 50-20 is +/- 0.01 mm (0.0004 in) with linear encoder feedback, which is standard for this class of hydraulic press brake. Stroke is 100 mm with an open height of 380 mm (15 in), suitable for a wide range of standard sheet metal operations — box and pan work, angle bending, channel forming, and light structural shapes. Ram speed is 100 mm/s approach with a bending speed up to 10 mm/s and return at 100 mm/s.

The standard back gauge on the HGB 50-20 is a 4-axis CNC system (X, R, Z1, Z2) with a depth range of 500 mm and travel speed of 500 mm/s. For most small to medium shop applications — box parts, brackets, simple channels — 4-axis back gauge is entirely adequate. Complex multi-step parts with asymmetric flanges or deep box sections may benefit from a 6-axis upgrade, available as an option.

Amada equips the HGB 50-20 with its AMNC-PC or equivalent touchscreen control, which handles 2D programming with automatic bend sequence suggestion, tool layout display, and back gauge position calculation. The control interface is straightforward for experienced fabricators, and offline programming connects to Amada's SheetWorks or AP60 software for shops that want to program at a CAD workstation rather than at the machine.

Crowning on the HGB 50-20 is handled via manual adjustment or mechanical crowning wedge — CNC-controlled crowning is not standard at this capacity and price point, though it may be available as an option on specific regional configurations. For a 50-ton machine bending parts under 2 meters, manual crowning adjustment is generally adequate; the deflection at 50 tons is much less critical than at 150–320 tons.

New HGB 50-20 machines typically run $90,000–$150,000 depending on back gauge configuration, tooling, and regional pricing. Used HGB series machines trade between $30,000 and $75,000. The HGB 50-20 competes directly with the TRUMPF TruBend 7036 (electric, premium), Bystronic Xpert 40/80 (hydraulic, European), and various domestic press brakes from Accurpress, Cincinnati, and Delem-equipped Asian-brand machines. The Amada brand carries a service and quality premium over the Asian-brand options; the HGB competes with Bystronic at similar price points.
