Overview
The Murata Wiedemann Genius 255 is a hydraulic CNC turret punch press from Murata Wiedemann (a Murata Machinery USA brand), targeting North American sheet metal job shops and fabricators. The Genius 255 offers 22-ton punching force on sheet up to 1270x2540 mm with a 26-station turret, making it suitable for medium-complexity punching work including bracket fabrication, panel knock-outs, and HVAC components. The hydraulic drive provides consistent punching force across the full sheet travel range, and the machine's C-frame design provides good access for operator loading of large sheets. Murata Wiedemann machines use the Siemens 840D sl CNC controller, one of the most widely supported and capable controls in the industry, enabling straightforward integration with third-party programming systems and CAM packages. The machine includes automatic slug control and a vibration-damped worktable for improved punching quality on light gauge material. Murata Wiedemann's North American service network through Murata Machinery USA provides domestic support.

Frequently Asked Questions
01
The Genius 255 punches stainless steel up to approximately 4mm at full capacity. Punching above 3mm stainless requires premium tooling and reduced stroke rates to manage cutting forces.
02
Yes. The machine can be paired with sheet loaders and part conveyors for semi-automated operation. Full automation with tower storage and sorting systems is possible with compatible Murata Wiedemann material handling equipment.
03
The Siemens 840D sl accepts programs from any CAM package with a 840D post processor, including Radan, SigmaNEST, Trumpf TruTops (in neutral formats), and Amada AP100. The control is not proprietary.
