Overview
The DMG Mori NZ QUATTRO is the flagship of the NZ production turning platform, packing four independent machining units into the workspace. When all four units are cutting simultaneously on the main and counter spindles, you are looking at cycle time reductions of 40-60 percent compared to conventional twin-turret machines on the right parts. This is the machine DMG Mori built for shops where every second of cycle time matters.
The workpiece envelope matches the rest of the NZ platform: 65 mm bar capacity, 120 mm max chuck diameter, 740 mm workpiece length on the short bed, and 1,290 mm on the long version. Each of the four machining units has its own Y-axis with 80 mm of travel, and B-axis capability with -10 to +100 degrees of swivel is available as an option.
The turnMASTER main spindle runs at up to 7,000 RPM with 5,000 RPM as standard and 174 Nm of torque. Milling spindles deliver 12,000 RPM for secondary milling operations. The TWIN spindle provides guide bush functionality at 5,000 RPM and can also serve as a steady rest or turning spindle at 4,000 RPM with 60 Nm.
CELOS with MAPPS on the Mitsubishi platform handles programming and monitoring. Four-channel simultaneous machining is where programming complexity peaks, and this machine essentially requires offline multi-channel CAM with full collision simulation. Shops that invest in the programming infrastructure see dramatic productivity gains, but the learning curve is steep.
The NZ QUATTRO sits at the top of the multi-unit turning market alongside machines like the Index G420 and Citizen Cincom A20. Its modular architecture with four independent B-axis-capable units is unique in the market and gives it geometric flexibility that competitors struggle to match.

Strengths & Limitations
Strengths
- Four independent machining units cutting simultaneously deliver 40-60 percent cycle time reductions on complex parts that utilize all stations
- Each unit has independent Y-axis and optional B-axis, providing unmatched geometric flexibility for compound-angle features
- turnMASTER spindle at 7,000 RPM with 174 Nm handles aggressive material removal in steel, stainless, and nickel alloys
- 12,000 RPM milling spindles eliminate the need for secondary VMC operations on most turned-and-milled parts
- TWIN spindle with Swiss-type guide bush function extends the machine reach into long slender part production
- Modular NZ platform means shared tooling, programming knowledge, and maintenance procedures across DUE, TRE, and QUATTRO
Limitations
- Four-channel programming complexity is the highest in the turning world and requires offline multi-channel CAM with collision simulation
- Starting around $550K and easily exceeding $800K fully loaded, the investment is substantial and needs high utilization to justify
- Overkill for simple parts where four units sitting idle on basic 2-axis work means you are paying for capability you cannot use
- Very limited used market since the platform is new and shops that buy QUATTRO-level machines tend to keep them running
- DMG Mori service contracts and spare parts carry premium pricing that adds to total cost of ownership

Frequently Asked Questions
01
New pricing runs $550,000-$900,000 depending on configuration. Full B-axis on all four units, long-bed option, high-speed milling spindle upgrades, and automation integration push the price toward the top end. Factor in another $50,000-$100,000 for offline CAM software and training.
02
Both are top-tier multi-unit turning centers. The NZ QUATTRO independent B-axis-capable machining units offer more geometric flexibility than the Index G420 turret-based approach. The Index has a longer track record and a stronger base of experienced operators. The choice often comes down to dealer support and which platform your operators already know.
03
Only if your parts can actually use them. The QUATTRO shines on complex parts with many features that allow four tools to cut simultaneously. If most of your work can be done with two or three units, the NZ DUE or NZ TRE will give you better return on investment. Run a cycle time analysis on your top 10 parts before deciding.
04
You need multi-channel turning CAM software with full synchronization and collision simulation. ESPRIT, GibbsCAM, and Mastercam all offer multi-channel support, but verify that your specific post processor handles four independent units with B-axis. Budget for post development and simulation validation.
05
Yes. The modular platform lets you use two, three, or four units depending on the job. You only activate what the part requires. This gives you flexibility to run simple jobs efficiently while having full four-unit capability available for complex production work.
