Overview
The Murata Wiedemann Multimac 6 is a high-capacity CNC turret punch press from Muratec (Murata Machinery), sold under the Wiedemann brand for the North American market, positioned as the flagship model in the Multimac series. The '6' designation refers to the machine's 60-ton (600 kN) punching force, which places it in the heavy-duty class of production turret punch presses alongside top-specification machines from Amada and Trumpf. The Multimac 6 is built for fabrication shops that process heavy-gauge steel, stainless steel, and aluminum sheet where the 20-30 ton force typical of mid-range punches becomes a limiting factor for forming operations, large-punch blanking, or thick material work.
The Multimac 6 operates on a servo-electric drive system, delivering the 600 kN peak punching force from a large-diameter servo motor and flywheel-assisted ballscrew ram. This servo-electric architecture provides programmable punch speed and stroke depth, enabling true-speed optimization — punching at full speed on open areas and slowing through the material for noise and vibration reduction. The working area accommodates sheets up to 2,500 x 1,270 mm (98 x 50 in) with a thick turret holding up to 58 stations including auto-index stations for angular feature punching. Maximum punching speed is 400 strokes per minute on small tools in repositioning mode.
Murata Wiedemann configured the Multimac 6 with a special emphasis on forming capability. The 600 kN force class supports large-diameter embosses, deep draws, lance-and-form operations, louver forming at heavy gauge, and threaded form tools in thicker material than the Multimac 4 can handle. Forming stations can be distributed across the thick turret to allow complex parts with mixed punching and forming requirements to complete entirely on the machine without secondary press operations. The CNC control — Murata Wiedemann's M-series with a 17-inch touchscreen — manages both punching and forming parameters with separate speed and stroke profiles per tool station.
New Multimac 6 systems are priced in the $350,000 to $550,000 range, positioning this machine for larger production fabrication shops, job shops with demanding forming requirements, and manufacturers where thick-gauge punching capability eliminates the need for a separate hydraulic press. The used market is less liquid than Amada or Trumpf at equivalent price points, but well-maintained Multimac 6 machines have appeared in the $120,000-$250,000 range through industrial dealers.

Strengths & Limitations
Strengths
- 600 kN (67.5-ton) punching force handles thick-gauge stainless steel and forming operations that 200-300 kN mid-range punches cannot perform reliably
- 58 tool stations with auto-index capability provides broad tooling flexibility for complex parts with angular features and varied punch geometries
- Servo-electric drive with programmable punch speed enables true speed optimization — full speed on repositioning, controlled speed through material — reducing noise and extending tool life
- Heavy-duty forming capability (large embosses, deep draws, louver forming) can eliminate secondary hydraulic press operations for many part families
- Thick turret tooling compatibility with Mate, Wilson, and Murata tooling gives shops multiple competitive suppliers for punches and dies
Limitations
- Smaller North American service and dealer network than Amada or Trumpf — service response in remote regions may require longer wait times
- 400 strokes/min is lower than top-end Amada and Trumpf servo-electric punches which reach 600-900 strokes/min on small tools
- Murata Wiedemann used market liquidity is lower than the major brands — finding well-maintained secondhand machines requires patience and broader search

Frequently Asked Questions
01
The Multimac 4 is Murata Wiedemann's mid-range turret punch with approximately 400 kN (45-ton) punching force and a smaller tool station count. The Multimac 6 provides 600 kN (67.5 tons), more tool stations (up to 58 vs. up to 47), a wider working area, and enhanced forming capability for heavy-gauge applications. The Multimac 6 is appropriate where the Multimac 4's force or forming capacity is a limitation — particularly for stainless steel above 4 mm or large-diameter forming operations.
02
Yes. The 600 kN force rating is sufficient for punching 6 mm stainless steel (Type 304 and 316), which requires approximately 50-70% more force than equivalent mild steel due to stainless's higher tensile strength and work hardening tendency. Stainless punching requires carbide-tipped tooling, precise clearances, and controlled punch speed to manage work hardening at the shear zone. The Multimac 6's servo-electric drive enables the precise speed control needed for consistent stainless steel results.
03
Murata Wiedemann has offered punch-laser combination machines under the Wiedemann brand, but the Multimac 6 in its standard form is a standalone turret punch press. Process integration with fiber laser cutting would require separate machine investment. However, the Multimac 6's heavy forming capability reduces the need for secondary processes on many part families, providing workflow simplification even as a standalone punch press.
04
The Multimac 6's additional 200 kN of force (600 vs 400 kN) enables louver forming in 4-6 mm steel (vs 2-4 mm on the Multimac 4), deeper lance-and-form operations, larger-diameter embosses in thick aluminum, threaded form tool (PEM clinching) operations in heavy gauge, and larger-diameter blanking. For shops working primarily with 1-3 mm material, this additional force rarely matters. For shops working with structural steel, heavy enclosures, or thick stainless, the difference is significant.
05
New Multimac 6 machines typically price between $350,000 and $550,000 depending on tooling package, auto-index station count, and automation options. Used machines are less common than equivalent Amada or Trumpf punches but have appeared in the $120,000-$250,000 range for well-maintained units through industrial dealers and auctions. Murata Wiedemann's service organization in Charlotte, NC supports the full Multimac installed base.
