Overview
The Amada HG 1703 is a 170-ton, 3-meter hybrid servo-hydraulic press brake from Amada's flagship HG series — the top tier of Amada's press brake technology featuring the highest precision, most advanced control, and optional Automatic Tool Changer (ATC) capability. With 1,700 kN of pressing force across a 3,100 mm bending length, the HG 1703 fills the tonnage gap between the popular HG-1003 (100 tons) and the heavy-duty HG-2204 (220 tons), serving fabricators who regularly work with medium-heavy gauge materials that push 100-ton machines to their limits.
The HG series dual servo power drive system combines hydraulic bending authority with servo-controlled precision. The system pressurizes the hydraulic circuit only during the actual bending stroke, cutting energy consumption approximately 30% compared to conventional hydraulic machines while reducing heat generation and extending oil life. Ram repeatability is rated at ±0.001 mm — the tightest specification in the production press brake category.
The AMNC 3i control with a 19-inch multi-touch LCD panel provides Amada's most comprehensive press brake programming environment, including 3D bend simulation, automatic bend sequence optimization, collision detection, and real-time springback compensation through the integrated bend sensor. The 8-axis backgauge with L-shift functionality handles complex multi-bend parts with varied shapes. The Bending Indicator system provides visual guidance to operators for consistent part orientation across bends.
The HG 1703 is available in ATC configuration, adding Amada's patented Automatic Tool Changer with stored tooling for hands-free tool setup. Complex tool layouts that take 30-40 minutes manually load in under 3 minutes with ATC. The ARs robotic bending cell variant adds integrated robot handling for fully automated bending production. For shops where 100 tons falls short and 220 tons is more than needed, the HG 1703 provides the premium precision and automation capability of the HG series at the optimal tonnage.

Strengths & Limitations
Strengths
- 170-ton capacity fills the gap between 100T and 220T machines, providing optimal tonnage for medium-heavy gauge fabrication on 3-meter sheets
- ±0.001 mm ram repeatability is the tightest specification available in production press brakes, virtually eliminating trial bends
- Optional ATC automatic tool changer loads complex tool layouts in under 3 minutes vs 30-40 minutes manual setup
- 8-axis backgauge with L-shift handles complex part geometries that would require manual repositioning on simpler machines
- 19-inch AMNC 3i with 3D bend simulation, collision detection, and integrated bend sensor provides the most advanced Amada control
- Dual servo power drive reduces energy consumption ~30% while maintaining full hydraulic bending authority
Limitations
- Premium pricing of $250K-$350K base ($450K-$580K with ATC) places the HG 1703 at the top of the market for 170-ton machines
- Amada proprietary tooling system and ATC tooling investment create significant vendor lock-in
- 14,000 kg machine weight requires proper foundation preparation and overhead crane access
- Hybrid servo-hydraulic system still requires hydraulic oil maintenance, unlike the all-electric EGB series

Frequently Asked Questions
01
The HG 1703 provides 70% more tonnage (170 vs 100 tons) on the same 3-meter bed. Choose the HG 1703 if you regularly bend material thicker than 5 mm mild steel at full length, work with heavy stainless or high-strength steel, or need tonnage headroom for demanding forming operations. The additional tonnage provides comfortable overhead without oversizing to the 220-ton HG-2204.
02
Amada's ATC stores punch and die tooling in integrated stockers and automatically loads the correct tool layout for each job. A layout that takes 30-40 minutes to set up manually loads in under 3 minutes. The ATC is the defining feature of the HG series and is not available on HRB or EGB series machines. It is the single biggest productivity improvement for high-mix fabrication shops.
03
With 170 metric tons across 3,100 mm, the HG 1703 air-bends mild steel up to approximately 10 mm at full bed length with standard V-die widths. On shorter bends, proportionally thicker material can be handled. This tonnage comfortably covers the medium-heavy gauge range that pushes 100-ton machines to their limits.
04
The HG 1703 delivers 170 tons (vs 130 tons HRB) with ±0.001 mm repeatability (vs ±0.01 mm), 8-axis backgauge with L-shift (vs 6-axis), 19-inch display (vs 15.6-inch), ATC option, and integrated bend sensor. The HRB 1303 costs roughly half the price of the HG 1703. The HG is the premium choice for precision and automation; the HRB is the value option for straightforward bending.
