Overview

The Amada HFB-O 100-3 is a combined CNC punch press and press brake system that integrates punching and bending operations on a single automated platform. The HFB-O designation reflects the machine's hybrid function: HFB stands for the hydraulic forming and bending capability, while the O suffix typically indicates the offline or automated bending execution mode. This configuration allows fabricators to process sheet metal through punching and then automatically transfer and bend parts without a separate press brake setup.

The system is designed to reduce the traditional two-step sheet metal workflow — first punching flat blanks on a turret punch press, then manually loading each blank into a press brake — into a single-machine automated cycle. The punched blank is positioned by the automated gripper system and presented to the bending unit in the correct orientation, with each bend executed according to the programmed sequence. This automation is particularly valuable for high-mix, medium-volume box and enclosure production where manual press brake operation creates a throughput bottleneck.

The punching section of the HFB-O 100-3 delivers 100 tons (approximately 1,000 kN) of punching force — substantially higher than standard turret punch presses — reflecting its role in processing heavier gauge materials or requiring high-force forming operations before bending. The bending unit accommodates the standard range of box and pan geometries including flanged panels, 4-sided boxes, and U-channels.

Amada's offline programming environment generates both the punch and bending NC programs simultaneously from the 3D part geometry, eliminating the need for separate CAM sessions for each process. The system includes material property compensation for springback in bending, improving first-article accuracy and reducing setup iterations.

The HFB-O 100-3 is positioned for precision sheet metal fabricators producing enclosures, chassis, instrument panels, and similar box-form parts at moderate-to-high volumes. The combined punch-bend approach dramatically reduces per-part labor compared to sequential manual operations, making it attractive for facilities with skilled labor constraints or high repeatability requirements.

Frequently Asked Questions

01 What is the main advantage of the HFB-O 100-3 over separate punch and bend machines?

The combined system eliminates the manual handling step of transferring punched blanks to a press brake. Each part is punched and bent in a single automated cycle, reducing labor, improving consistency, and enabling unmanned or lightly staffed operation for box and enclosure production.

02 What part geometries is the HFB-O 100-3 best suited for?

The system is optimized for box and pan geometries including flanged panels, 4-sided boxes, U-channels, and instrument chassis. Parts requiring multiple bends on a flat blank produced from the punch section are ideal candidates for the integrated punch-bend workflow.

03 How is the HFB-O 100-3 programmed?

Amada's offline CAM system generates both the punch NC program and the bending sequence from the 3D part model simultaneously. Springback compensation values are applied automatically based on material properties and bend parameters, reducing the number of first-article iterations needed.

04 What material thicknesses does the HFB-O 100-3 process?

The system is optimized for sheet metal in the range of 0.8 mm to approximately 3.2 mm mild steel, the typical range for enclosure and panel fabrication. Exact maximum thickness depends on the specific configuration and bending tool setup.

05 Is the HFB-O 100-3 available with automation for lights-out operation?

The HFB-O platform is itself an automated combination machine. Additional integration with sheet storage towers and part sorting systems can extend unmanned operation time. Full lights-out capability requires careful part geometry analysis to ensure consistent blank handling throughout the punch-bend cycle.
