Overview
The DMG Mori DMU 210 P is a large 5-axis portal machining center designed for shops machining very large, heavy workpieces that require simultaneous 5-axis contouring. The "210" refers to the 2,100 mm X-axis travel on the portal bridge, and the "P" designates the portal (gantry) configuration that allows the workpiece to sit stationary on the floor-mounted table while the spindle head traverses the full working envelope. This is the machine for aerospace structural components, large turbine casings, ship propulsion housings, mold and die work on large-format tooling, and energy sector manifolds that would require multiple setups on any smaller 5-axis machine.
The spindle delivers 37 kW (49.6 hp) at 8,000 RPM with 400 Nm of torque through an HSK-A100 interface. Optional high-speed spindle heads step up to 18,000 RPM for aluminum aerospace machining at high material removal rates. The swiveling milling head (B-axis ±110°) combined with a rotary C-axis on the table provides full 5-axis simultaneous capability, enabling contoured aerospace surfaces, compound angle bores, and complex ported geometry in a single setup. X/Y/Z travels reach 2,100 × 1,600 × 1,000 mm with table load capacity up to 10,000 kg.
The monoBLOCK-inspired portal structure uses a symmetrical bridge design that minimizes thermal distortion across the full travel range. Direct Drive C-axis on the rotary table provides backlash-free angular positioning, while the B-axis swiveling head uses high-precision gearing. All linear axes use roller guideways for the rapid traverse/rigidity balance demanded in production. The 60-tool magazine is expandable to 120 or more for complex 5-axis work with large tool libraries.
CELOS with Siemens 840D sl operates on a 21.5-inch ERGOline touchscreen. At $1,200,000–$1,800,000 configured, the DMU 210 P competes with the Hermle C 62 U, Starrag LX 151, and Makino MAG-V series. Shops that have justified 5-axis machining on smaller platforms and are now winning contracts for larger aerospace, energy, and tooling work will find the DMU 210 P provides the envelope, accuracy, and surface quality needed to compete at the highest level.

Strengths & Limitations
Strengths
- 2,100 × 1,600 × 1,000 mm travel envelope and 10,000 kg table load open up large aerospace structural components, turbine casings, and heavy mold tooling that smaller 5-axis machines cannot reach in a single setup
- Simultaneous 5-axis contouring via B-axis swiveling head and C-axis rotary table enables compound-angle features, contoured aerospace surfaces, and complex ported geometry without part repositioning
- Optional 18,000 RPM high-speed spindle head for aluminum aerospace work provides exceptional surface finish and material removal rates on large aircraft structural parts
- Portal bridge design minimizes thermal growth across the long travel range, maintaining accuracy on extended production cycles for tight-tolerance aerospace work
Limitations
- Machine weight approaching 80,000 kg demands major site preparation with deep reinforced foundations, high-capacity overhead cranes, and specialized installation teams — typically adding $300,000+ to project cost
- At $1,200,000–$1,800,000, this machine requires a clear large-part production pipeline to achieve acceptable ROI; underutilization on a machine this size is very expensive
- Programming complexity for full 5-axis work on large, complex parts requires highly skilled programmers, advanced CAM software, and careful collision avoidance in the simulation environment

Frequently Asked Questions
01
A new DMU 210 P starts around $1,200,000 in standard configuration. Fully configured with high-speed spindle head, 120-tool magazine, high-pressure through-spindle coolant, on-machine probing, and automation integration, the total typically reaches $1,500,000–$1,800,000. Foundation and installation engineering add significant cost beyond the machine price. These are typically financed through DMG Mori Financial Services or major bank lending.
02
The DMU 125 P Duoblock is a mid-size 5-axis portal machine with 1,250 mm X travel and up to 3,000 kg load capacity, targeting aerospace and mold shops in the mid-size range. The DMU 210 P provides 2,100 mm X travel and 10,000 kg load capacity for significantly larger workpieces. The Duoblock architecture on the 125 P emphasizes two-column rigidity; the DMU 210 P uses a portal bridge. The 210 P is chosen when workpiece length or weight exceeds what the 125 P can accommodate.
03
Yes. The standard 37 kW / 400 Nm HSK-A100 spindle handles titanium Ti-6Al-4V aerospace work with appropriate tooling strategies. High-pressure through-spindle coolant (80 bar option) is recommended for titanium to manage heat and tool life. Large titanium aerospace structural members — wing ribs, bulkheads, door surrounds — are a primary target application for the DMU 210 P.
04
For simultaneous 5-axis work on large complex parts, hyperMILL (Open Mind), Siemens NX CAM, and Esprit Flow are the most commonly used packages. All provide DMG Mori DMU portal post-processors and Siemens 840D sl output. Machine simulation with collision avoidance is essential given the large working envelope and heavy workpiece values; all three platforms provide this. Dassault CATIA and ICAM post-processing are also common in aerospace supply chains.
05
The Hermle C 62 U is a respected large-format 5-axis machine known for exceptional accuracy and surface finish, targeting mold, die, and precision aerospace work. The DMU 210 P offers a significantly larger working envelope and higher table load capacity, making it better suited for the heaviest workpieces. Hermle's reputation for precision is very strong in mold and die; DMG Mori's portal architecture provides more flexibility for diverse heavy-industry work. Both compete at similar price points for large-format 5-axis machining.
