Amada AC NT punch pressés

Slug pulling-less processing
Stable, high-speed processing is achieved with less slug pulling The AC-NT series uses a power vacuum system that strong downward airstream will be generated inside the die to extract slug. Small- diameter slug pulling can be effectively prevented. As a result, processing can be achieved at a shallow bottom end (or with a die penetration of 1 mm). The optional slug suction unít can be used in combinatíon to prevent large-diameter slug pull.

Fine contouring
No special tools are required. Special shapes and radi can be processed as successfuily as by laser cutting. Nibbling at a pitch that is less than the material thickness. As a result, filling after processing is no longer necessary. The number of hits increases, but the speed increases to sharply reduce the processing time.

3. High-speed deburring
Labor and time consuming deburrng is automated and speeded up. The bottom surface of the workpiece is equally pressed against the C-shaped die tip to remove the burrs. This deburring tool is setup to be used after follow-up punching

4. Slotting
Edges are cut wíthout tool overlap marks that otherwise require file finishing. The slotting tool is installed in a 2 auto-index station. It can produce overlap mark-free edges at any desired angle.

5. High-speed marking
Secondary operatíons are markediy enhanced in efficiency. A hit rate of 900 min- is achieved. Part names, lot numbers, bend lines, weld positions, and similar information are marked to greatly improve the efficiency of secondary operations.

6. High-speed forming
Parts can be formed to desired shapes and dimensions without using special tools. Offset bending and other forming operations were separately performed in the past. Auto-index stations can now be used to offset bend or otherwise form parts to desired shapes and dimensions at high speed. Process integration can be thus achí=ieved.

7. Down-forming
Parts can be down-formed at high speed without damage and without collapsing formed features. A floating brush table allows parts to be form-down extruded and tapped without damage. Process integration can be achieved as a result.
Floating brush table
When the workpiece is to be moved after down-forming, the brush table around the turret rises 5 mm to prevent the interference between the die and workpiece. This feature eliminates the program restriction during forming and accelerates the forming speed.

8. Safety inch bending
Minute flanges can be automatically bent. Downward bends can be formed with burrs orienting inward. Minute flanges and round flanges against which the backgauge has not been capable of being applied
can now be formed.

Drive mechanism
The AC-NT series uses an single AC servo drive system. Marking at a hit rate of 900 min-1 is accomplished. The drive mechanism is contained in the bridge frame. The press drive that uses a highly durable ball screw and link combination achieves high-speed stable processing with high productivity.

Ecoiogy
Despite its high hit rate, the AC-NT series consumes only power. Its standby power consumption is the smallest of Amada's turret punch presses. Low power consumption is also achieved during processing at high hit rate. Other environmental considerations, as elimination of hydraulic oil change, are implemented.

High rigidty
The bridge frame of the AC-NT series is 40 mm in thickness, heavier gauge than that of the PEGA and VIPROS and is designed with high rigidity. This high rigidity bridge frame construction provides for high-speed, stable, highaccuracy processing over a long period of time.

Intelligence
The AC-NT series is equipped with a network-enabled AMNC/PC system.
Tool setup, guide input program creation and editing, and press pattern
control functions enable the AC-NT series to perform a wide variety of processing operations. The overload detection function detects an overload and protects the AC-NT series from the overload. This function ensures the operation of the AC-NT series at an optimum load and prolongs its service life.

Large-capacity turret
The turret can carry up to 58 tools.
The tool setup time is reduced to improve productivity. The 120 mm
thick turret securely holds the tools during high-speed processing and supports the high-accuracy processing of the AC-NT series.

Space-saving
The AC-NT series achieves a Y-axis stroke of 1270 mm. It has a large capacity turret carrying up to 58 tools.

Tool balancer
The tool balancer is used to load a large-diameter tool in the turret or unload a large-diameter tool from the turret. It facilitates and accelerates the setup of tools, alleviates the workload of the operator, and enhances the operating rate of the AC-NT series.

Amada proposes a digital sheet metal fabrication system with its virtual prototype simulation system (VPSS) as core. The processing data created in the factory office are managed together by the SDD and called through the network for use at the factory floor.
