Murata Wiedemann Multimac 8

The Murata Wiedemann Multimac 8 is the flagship CNC turret punch press in Muratec's (Murata Machinery) Multimac series, sold under the Wiedemann brand in North America. The '8' designation refers to the machine's 800 kN (approximately 90-ton) punching force — the highest in the Multimac range and one of the highest punching force ratings available in a production CNC turret punch press. At 800 kN, the Multimac 8 enters territory typically associated with large hydraulic ironworkers and heavy press punching operations, enabling turret punch press versatility and CNC programmability for applications in thick structural steel and heavy industrial fabrication where lower-force machines are simply inadequate.

The Multimac 8 is built on a heavily reinforced frame to accommodate the 800 kN force class. The machine uses a servo-electric drive with flywheel-assisted ballscrew ram — the flywheel stores rotational energy to deliver peak 800 kN force on demand without requiring a proportionally enormous motor. This servo-flywheel architecture is characteristic of high-force servo punch presses that need instantaneous peak force while maintaining servo-electric benefits: programmable punch speed, reduced noise compared to full hydraulic machines, and energy recovery during deceleration. The working area extends to 2,500 x 1,270 mm with a thick turret holding up to 58 stations including auto-index positions.

The applications that justify the Multimac 8's 800 kN force class are specific: punching thick mild steel (8-10 mm) with large punch diameters, blanking structural shapes from heavy-gauge stock, forming deep draws or large-area embosses in thick material, and processing materials like tool steel plate or high-strength structural steel (S355, S420) where standard 300-600 kN machines operate at or beyond their limits. In these applications, the Multimac 8 provides consistent, repeatable results with CNC precision — a significant advance over dedicated hydraulic tooling presses that lack X/Y automation and turret versatility.

Murata Wiedemann configures the Multimac 8 with the company's M-series CNC control featuring a 17-inch touchscreen and full offline programming capability. The machine's thick-turret tooling system accepts Murata Wiedemann's own tooling catalog as well as compatible tooling from Mate Precision Technologies, Wilson Tool, and other standard thick-turret suppliers. Auto-index stations allow angular feature punching without sheet rotation, enabling complex parts with radial hole patterns and angular slots to be completed without setup changes.

New Multimac 8 machines are priced in the $500,000 to $800,000 range, reflecting the heavy-duty construction, 800 kN force class engineering, and production punch press capability at the extreme end of the turret punch market. This price range positions the Multimac 8 for large production fabrication shops, defense and heavy industrial contractors, and structural fabricators where the 800 kN capability addresses a genuine production requirement. Used Multimac 8 machines are rare on the secondary market given the specialized nature of the machine and the tendency for high-force punches to remain in service at original purchasers for 20+ years.
