Overview
The DN Solutions DCM 3280 F II is a massive double-column machining center with W-axis crossrail designed for workpieces that won't fit on anything else. We're talking 8,250 mm (325 in) of X-axis travel, 3,700 mm (146 in) on Y, and 700 mm (28 in) on Z. That's over 27 feet of longitudinal travel — this machine eats large aerospace structures, shipbuilding components, and heavy-equipment frames for breakfast.
The double-column architecture gives the DCM 3280 F II inherent rigidity that cantilever designs can't match. The crossrail moves vertically on the W-axis, letting you adjust the working height to accommodate different part profiles without sacrificing stiffness. At 94,000 kg (207,235 lb), this machine isn't going anywhere during a cut. That mass translates directly into vibration damping and surface finish quality on large-scale parts.
Rapid traverse rates run 16 m/min on X, 20 m/min on Y, and 15 m/min on Z. Those aren't speed records, but on a machine this size, positioning accuracy matters more than rapids. The table handles workpieces up to 45,000 kg (99,208 lb), which covers most large structural components you'd encounter in energy, defense, or heavy industrial work.
DN Solutions builds the DCM series at their dedicated large-machine facility, and the F II generation brought improvements in thermal compensation and geometric accuracy. If you're machining parts measured in meters rather than millimeters, the DCM 3280 F II is built for that scale.

Strengths & Limitations
Strengths
- 8,250 mm X-axis travel handles workpieces over 27 feet long — covers large aerospace, shipbuilding, and energy components
- Double-column construction provides symmetric rigidity that eliminates the deflection issues of cantilever-type machines
- W-axis crossrail adjusts working height to accommodate different part profiles without losing stiffness
- 45,000 kg table capacity handles the heaviest structural components in heavy industry
- 94,000 kg machine weight delivers outstanding vibration damping for superior surface finish on large parts
- F II generation includes improved thermal compensation for better geometric accuracy during long machining cycles
Limitations
- 700 mm Z-axis travel is relatively limited for a machine this size — deep-cavity work requires careful planning
- Enormous footprint and 94-ton weight demand serious foundation engineering and rigging equipment
- Rapids of 16 m/min on X mean long positioning times across the full travel range
- Lead times for machines this size typically run 12-18 months from order

Frequently Asked Questions
01
Expect to invest $800,000 to $1,500,000 depending on spindle configuration, tooling, and accessories. Machines in this class are typically quoted on a project basis. Installation and foundation work can add another $100,000-$200,000.
02
The DCM 3780 increases Y-axis travel from 3,700 mm to 4,400 mm and Z-axis from 700 mm to 1,000 mm, while keeping the same 8,250 mm X-travel. It also weighs 112,000 kg versus 94,000 kg. Choose the 3780 when you need more cross-travel and depth capacity.
03
This machine targets large-scale structural components: aerospace wing spars, shipbuilding plates, turbine housings, large mold bases, heavy equipment frames, and defense components. Anything measured in meters that needs precision machining on multiple surfaces.
04
The crossrail moves vertically on the W-axis between the two columns, adjusting the spindle's working height independent of the Z-axis stroke. This lets you position the spindle closer to tall or short workpieces while maintaining maximum Z-axis travel for the actual cutting.
