The CNC punching machine series AC – Intelligence & Innovation at its highest level

For more than four decades, AMADA has stood for the highest quality and efficiency in the field of machine tools. During this time, we have consequently integrated our theoretical knowledge and practical experience into all of our constructions. Our innovations have always been exactly suited to the needs and requirements of our customers. Therefore, the AC series represents another milestone in CNC punching machine technology.

The AC models – the economical introduction to AMADA punching technology at delivering the highest level of performance. Its trend-setting, servoelectric motor combines all advantages of mechanical punching technology with the speed and flexibility of hydraulic highspeed punching machines. The proven AMNC controller ensures maximum precision while being easy to operate. In addition, the standard specifications of the AC-255 NT and the AC-2510 NT hardly leave anything more to be desired.

Efficiency & effectiveness for your success

The servo-electric driven AC CNC punching machine series opens up a completely new perspective for sheet metal processing. Two models are available, the AC-255 NT and the AC-2510 NT CNC punching machine, which distinguish themselves by an exceptional price-performance ratio.
Thanks to the AC CNC punching machine series, you can increase production speed and profit from the precision and functionality of reduced setup times and costs. Once again, this expands the economic, meaningful range of application for CNC punching technology.

State-of-the-art technology ensures the best functionality and productivity. The AC CNC punching machine series as already successfully proven itself under difficult practical conditions.

Excellent features are already part of the standard specification of the AC CNC punching machine. For even more flexibility, additional optional functions are available to deal with all sheet metal requirements.

Easy operation by menu-guided user-friendly technology. The easy operation considerably increases the entire productivity.

A CNC punching machine with maximum cost-efficiency

Among other things, the very good priceperformance-ratio of the CNC punching machine is a result of the low acquisition costs and the absence of maintenance costs and the resulting costs caused by downtimes. The considerably increased range of application in terms of forming and complete processing also contributes to the high cost-effectiveness of the AC CNC punching machine series.

Highly economic CNC punching machines with maximum convenience of operation

Together with the highly accurate servoelectrical drive, the proven bridge frame is an essential construction feature for guaranteeing high-quality results, even after years of operation.

Powerful for saving energy

The servo-electric drive combines the highest productivity with the lowest operating costs. This drive has proven itself during tests with 100 million load cycles. In contrast to the already familiar problems of conventional punching processes, the servo-electric punching operation only has advantages – there are no known disadvantages.
On average, the power requirement of the drive is 3.5 kW respectively 0.7 kW in standby mode and therefore considerably less than the power requirements of a comparable hydraulic punching machine. One of the largest savings factors is the innovative power recovery concept.
Surplus energy from the braking process is buffered and used for re-acceleration.

Processing reliability with system

Two systems are available for punch slug removal.
They ensure higher process reliability for the CNC punching machine:
Power vacuum and the central vacuum removal for punch slugs. In particularly, slugs are ejected reliably from the process during high-speed punching and damage to the work piece is there fore avoided.

Reliable – scratch-free

The AC CNC punching machine is equipped with a brush table and a lifting brush table for scratch-free, high-quality processing that can be programme-controlled to lift approximately 5 mm to avoid scratching the workpiece. This function even enables reliable processing of downward-direction forming such as threaded nozzles.
