AC 255/2510NT AC SERVO DRIVE TURRET PUNCH PRESS
Amada’s New AC-NT Series Servo Drive Turret
and Reduced Operating Cost in One Package.
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.

Reliable High-Speed Processing
1. Eliminate Slug Pull
2. Fine Contouring
Slug 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.
Fine 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.

Air Blow Tool & Power Vacuum Die
Power Vacuum Slug Suction System (Standard on most models)
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.
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.

Reduced Secondary Operation Costs
3. High-Speed Deburring
4. High-Speed Slotting
High-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.
Perform 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 Marking
Using 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.

Punching & Bending Process Integration
6. High-Speed Forming
7. Down-Forming
Parts 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.
A 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 Bending
Automatically 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.

AC-NT Functions & Mechanisms
Drive Mechanism
Highly Rigid Frame
The 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.
Amada is the originator of the
bridge frame turret punch press.
The precision-welded and stressrelieved 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.
Intelligent, Reliable &
Easy-to-Use Controls
Large Capacity
Turrets
The 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.
The 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 autoindex. 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.
1.57"
Space Saving Design
Ecology & Reduced Power Requirements
Despite 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.

Even with the optional 58-station
turret, the AC-NT series features
a footprint smaller than that of
the Aries 245-II. The AC-NT
series means there's no need
to compromise quality and
production rates just because of
floor space restrictions.
Tool setup
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.
Pneumatic Tool
Balancer
A pneumatically-operated tool
balancer makes the loading and
unloading of large station tools
faster, easier and safer.
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.
