Amada AC-255NT
Amada is known worldwide as the leader in turret punch press technology with
more than 30,000 machines in operation. The AC 255NT 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.
