Amada is known worldwide as the leader in turret punch press technology with more than 30,000 machines in operation. The AC 255/2510NT was developed as a part of our ongoing mission to provide the widest range of punching solutions.
The AC-NT series utilizes an AC servo motor to drive the ram (eliminating the •hydraulic power supply and chiller).
Electrical consumption is less than one-half of comparable hydraulic •machines.
The AC-NT offers significantly faster punching speeds than mechanical turrets.•
Space-saving design makes the most of valuable floor space.•
The AC-NT series turret punch press is packed with a wide variety of standard features to help produce parts faster, easier and more economically.

Filing Not Required Special Tool Not Required
1. Eliminate Slug PullSlug pull is often a problem when punching at high speeds, especially with small diameter holes. This nuisance is virtually eliminated through the use of the power vacuum die and air blow tool systems included standard with Amada AC-NT series turrets. A powerful stream of precisely-mixed air and oil inside the die helps pull slugs safely downward, greatly reducing the chance of shutdowns, scrapped parts and broken punches. In addition, punch penetration can be reduced, thus increasing total hits per minute, while increasing tooling life.
2. Fine ContouringFine Contouring with the AC-NT Achieves Laser-Like Precision!Using Amada’s special contouring tool, the machine nibbles at a pitch as small as 0.020" to punch complex curves and shapes at high speeds. This is impossible with typical turret punch press tooling. As a result, it is possible to eliminate secondary processing such as filing and deburring.
Slugs are powerfully vacuumed out of the die to prevent slug build-up. The slugs are deposited either into a bin or onto a conveyor (supplied by customer) for easy handling.
The air blow tool blows air and oil mist into the die during punching to prevent slug sticking and pulling. The power vacuum extracts the slug down through the die.

Reliable High-Speed Processing
3. High-Speed DeburringHigh-Speed Deburring Reduces Processing Time Dramatically.Reduce costly and time-consuming, post-punch deburring by doing the work "in the sheet." Using the deburring tool, the burrs raised during punching are flattened-out, helping to streamline manufacturing processes.
4. High-Speed SlottingPerform Slotting Without Overlap Marks.The slotting tool (installed in a 2" auto-index station) is capable of producing overlap mark-free edges at any desired angle. This helps eliminate secondary filing or grinding.
5. High-Speed MarkingUsing the marking tool at speeds of up to 900 hpm, reduce secondary operation time by adding part names, part numbers, bend lines, weld locations and other information. Punch penetration is accurately controlled so that the marks can be subsequently covered by paint, powder coat, etc.

Reduced Secondary Operation Costs
6. High-Speed FormingParts can be formed to desired shapes and dimensions without special tools. Previously, punching and forming often had to take place in separate operations. Now, offset bends, extrusions, ribs and other forms can be added at high speeds, using standard tools in the auto-index stations.
7. Down-FormingA floating brush table section allows parts to be formed-down or extruded at high speeds without damage to the feature during subsequent sheet movements. This helps reduce secondary processing and re-working.
8. Safety Inch BendingAutomatically add small, accurate bends and flanges. Downward flanges can be formed with burrs oriented inward. Adding these bends while parts are still "in the sheet" eliminates tedious, potentially dangerous secondary press brake operations.

Drive MechanismThe AC-NT series uses a single AC servo motor, along with a heavy duty precision ball screw and link assembly, which is mounted in the bridge frame to achieve hit rates of up to 390 hpm on 1" centers (depending on model and stroke length) and up to 900 hpm marking speeds. The drive mechanism features fewer components than any hydraulic system for increased reliability and uptime. A built-in load monitoring system shows actual tonnage requirements and combined with a shear plate helps to greatly reduce the chance of damage due to overload. The drive has been tested at over 100 million hits at full tonnage with no failures.
Ecology & Reduced Power RequirementsDespite high hit rates, the AC-NT series requires only a 19 kVA power hookup. Average total electrical consumption during punching is less than half of a typical hydraulic machine and standby power requirements are the lowest of any Amada turret punch press. Unlike a hydraulic machine, no fluid change or chiller maintenance is ever required.
Highly Rigid FrameAmada is the originator of the bridge frame turret punch press. The precision-welded and stress-relieved frame is made using 1.57" thick steel plate to help ensure stable, reliable production, while providing increased tooling life and reduced punching noise over many years of day-in and day-out production.
NT technology means users can perform offline programming and monitor the operational status of the machine from any desktop computer or web-based connection to your network.
The AC-NT can be equipped with an optional interface for automatic sheet loading and unloading using Amada's MP loaders, reducing labor costs and improving productivity.
Pneumatic Tool BalancerA pneumatically-operated tool balancer makes the loading and unloading of large station tools faster, easier and safer.
Intelligent, Reliable & Easy-to-Use ControlsThe AC-NT series is equipped with the proven Fanuc AMNC/PC control system to help increase productivity. A wide variety of touch screens allow the operator to view turret setup, job and material data, and scheduling, providing faster, easier and more mistake-proof operation than ever. An overload detection function shuts the machine down before damage can occur.
Large Capacity TurretsThe AC-NT series of servo drive turret punch presses feature Amada's legendary triple-track turret, with up to 58 laser-hardened stations, including up to four auto-index. Thick-style tooling has been proven to last longer under tough punching conditions. The wide range of sizes (up to 4 ½", depending on model) and large number of stations means that multi-tools are rarely required, but can be used if desired.
