at maximum tonnage. The ram servo motor has been designed parallel with the press frame. This provides a com- pact frame generating minimum stress, optimal rigidity and improved hole quality and tool life.
Model M3048TG offers a maximum sheet size (without repositioning) of 49 by 98.5 in.; Model M3058TG, 60 by 98.5 in. Punching accuracy: ±0.004 in.
The included Fanuc control features Murata’s Intelligent Control touch- screen interface to help minimize setup time.

Amada Debuts Fiber-Laser Welder
Amada America recently introduced the FLW 4000 M3 4-kW fiber laser, designed for high-speed precision welding while providing substantial electrical sav- ings. Continuous-waveform welding ensures high-speed, smooth results that cannot be achieved by pulse welding, even when processing reflective materials such as brass and copper and combinations of dis- similar materials.
The FLW boasts a patented rotating lens—rather than the laser beam being aligned with a specific point along the target path, it instead circles within a small area as it welds. This feature allows the beam to bridge relatively large and uneven joint gaps while producing clean, even welds.
Heat input into the workpiece mate- rial is optimized and results in precise- ly defined weld edges with virtually no unnecessary deposits of weld metal.
