Overview

The DMG Mori NZ TRE is the three-unit variant of the NZ production turning platform, stepping up from the NZ DUE by adding a third independently positionable machining unit in the workspace. That third unit unlocks simultaneous three-tool cutting on the main spindle or allows overlapping operations between main and counter spindle work, which can slash cycle times by 30-40 percent on complex parts compared to a twin-turret setup.

Bar capacity is 65 mm and chuck work runs up to 120 mm diameter, identical to the DUE. Workpiece length is 740 mm on the short bed and 1,290 mm on the long version. Every machining unit carries a Y-axis with 80 mm of travel, and B-axis with -10 to +100 degrees of swivel is available as an option on each unit. That means you can run three independent tool positions with angular capability simultaneously.

The turnMASTER main and counter spindles deliver up to 7,000 RPM with 174 Nm of torque, and the milling spindles run at 12,000 RPM. The TWIN spindle provides guide bush functionality at 5,000 RPM for Swiss-type work on long slender parts, plus it can serve as a hydraulic steady rest when you need rigid support.

CELOS with MAPPS on the Mitsubishi control platform handles the programming and monitoring side. With three units running simultaneously, programming complexity goes up significantly, so shops typically need operators with multi-channel turning experience or invest in offline CAM simulation. The NZ TRE competes against machines like the Index G220 and Nakamura-Tome Ntrex-1000 in the three-turret category. Its modular architecture with independent B-axis units gives it an edge on geometric flexibility, but the programming learning curve and price premium are real considerations.

Strengths & Limitations

Strengths

Three independent machining units enable simultaneous three-tool cutting, reducing cycle times 30-40 percent on complex parts versus twin-turret machines
Each unit gets its own Y-axis and optional B-axis, providing geometric flexibility that fixed turret machines cannot match
turnMASTER spindles at 7,000 RPM with 174 Nm deliver enough torque for aggressive roughing in steel and stainless
12,000 RPM milling spindles mean serious secondary milling capability without tying up a separate VMC
TWIN spindle with guide bush function handles Swiss-type work on long slender parts without needing a dedicated Swiss machine
Modular NZ platform shares tooling, programming logic, and maintenance procedures with the DUE and QUATTRO variants

Limitations

Three-channel programming complexity requires operators with multi-turret experience or significant offline CAM investment
Price premium over twin-turret lathes is substantial, with the third unit adding over $100K to the machine cost
Setup times on simple 2-axis turning jobs are longer than necessary since you are paying for capability you are not using
Very new platform with limited used market availability and still-evolving application support

Best For

High-volume production shops where cycle time reduction on complex parts justifies the three-unit investment Automotive transmission component manufacturers running shafts and gears with multiple cross-features Aerospace shops machining actuator housings and fittings that need simultaneous turning, milling, and drilling Contract manufacturers bidding on complex multi-op parts where consolidated operations win the quote Medical implant production requiring tight tolerances held across multiple simultaneous cutting operations

Frequently Asked Questions

01 How much faster is the NZ TRE compared to the NZ DUE?

On parts that can utilize all three machining units simultaneously, the NZ TRE typically cuts cycle times by 30-40 percent compared to the two-unit DUE. The actual gain depends on part geometry and how well you can balance the cutting operations across three units. Simple parts with few features may see minimal improvement.

02 What does a new DMG Mori NZ TRE cost?

New pricing runs $450,000-$700,000 depending on configuration. B-axis options, long-bed variant, and high-speed milling spindle upgrades all add to the base price. The third machining unit adds roughly $100,000 or more over the NZ DUE configuration.

03 Do I need special CAM software for the NZ TRE?

While you can program the NZ TRE at the control using MAPPS conversational programming, most shops running three simultaneous machining units invest in offline multi-channel CAM software with simulation. This lets you verify synchronization and avoid collisions before running the program on the machine.

04 Can I run the NZ TRE with only two units active?

Yes. The modular platform lets you use two or three units depending on the job. For simpler parts, you can run it like the NZ DUE with two active units. The flexibility to scale up to three-unit cutting when the part demands it is one of the platform's key selling points.
