Overview
The DN Solutions PUMA DNT 2100 MB is the 10-inch chuck variant of the DNT 2100 mill-turn series. It steps up from the 8-inch chuck DNT 2100 M to give shops more clamping capacity for mid-size parts while keeping the same compact footprint. If your parts occasionally exceed what an 8-inch chuck can hold, or you need more torque for heavy cuts in tough materials, the MB is the right call.
The spindle delivers 18.5 kW (24.8 hp) with 403 Nm (297 ft-lb) of torque at up to 3,500 RPM. That's 23% more torque than the 8-inch M variant, at the cost of 1,000 fewer RPM. For steel and stainless production work in the 10-inch chuck range, 3,500 RPM still provides excellent surface speed on most part diameters.
Max turning diameter is 320 mm (12.6 in) with 501 mm (19.7 in) of turning length. Those are slightly smaller numbers than the M variant because the 10-inch chuck takes up more space inside the enclosure. X-axis travel is 230 mm (9 in) and Z-axis provides 580 mm (22.8 in). Rapids match the M at 24 m/min on X and 30 m/min on Z.
The 12-station turret runs live tools at 6,000 RPM for cross-drilling, tapping, and milling operations. That live tool speed is generous for this machine class and lets you push small endmills and drills harder than many competitors. The DNT generation brings improved thermal stability and the latest FANUC 0i-TF Plus control with iHMI touchscreen.
At 3,900 kg (8,598 lb), the MB is only 100 kg heavier than the M variant and shares the same 2,945 mm (116 in) footprint. It's a straightforward decision: if your parts need more than 8 inches of chuck, you go with the MB. If you need the extra RPM more than the extra chuck size, stick with the M. Both are solid production machines at a competitive price. Specs sourced from DN Solutions published data.

Strengths & Limitations
Strengths
- 10-inch chuck handles mid-size parts that won't fit in an 8-inch — a common step-up for growing shops
- 403 Nm of torque is 23% more than the 8-inch M variant, improving heavy roughing capability
- 24/30 m/min rapids keep non-cutting time low for production cycle time optimization
- 6,000 RPM live tooling handles cross-drilling, tapping, and milling without secondary setups
- Same compact 2,945 mm footprint as the DNT 2100 M — no extra floor space needed for the bigger chuck
- Latest DNT generation with improved thermal compensation and FANUC 0i-TF Plus with iHMI
- Competitive pricing against Haas ST-25Y, Mazak QT-250, and Okuma LB3000 EX II
Limitations
- 3,500 RPM spindle speed is 1,000 RPM less than the M variant — limits surface speed on small-diameter aluminum
- 501 mm max turning length is slightly less than the M's 513 mm due to the larger chuck assembly
- 18.5 kW spindle power is shared with the M — no extra horsepower despite the larger chuck
- No sub-spindle standard — done-in-one parts need the MS variant
- No Y-axis on the base MB model limits off-center milling to C-axis interpolation

Frequently Asked Questions
01
If your parts regularly need more than 8 inches of chuck, the answer is yes. The 1,000 RPM difference (3,500 vs 4,500) only matters on small-diameter aluminum work. For steel and stainless in the 10-inch chuck range, 3,500 RPM provides more than enough surface speed, and the extra torque (403 vs 328 Nm) helps on heavier cuts.
02
The through-bore diameter depends on the specific spindle configuration, but the 10-inch chuck typically accommodates bar stock up to about 65-76 mm diameter. For exact bore specifications, check with your DN Solutions dealer. Bar feeder integration is a standard option for unattended production.
03
Both use a 10-inch chuck with similar turning capacity. The DNT 2100 MB is in the PUMA series (box-way construction, heavier, more rigid) while the LYNX 2100 LMC uses linear guides (faster rapids, lighter). The PUMA DNT also gets a larger turning envelope and more robust turret. Choose the PUMA for heavier cuts; the LYNX for faster cycle times on lighter work.
04
Yes. A parts catcher or parts conveyor is a common option for production environments. It works well with bar feeder setups for unattended lights-out running of small to mid-size parts that can be ejected after cutoff.
05
DN Solutions (formerly Doosan Machine Tools) has a well-established dealer network across North America, Europe, and Asia. Most major metro areas have local dealer service technicians. The FANUC control is also independently supported by FANUC's own service network. Parts availability is generally good given the large installed base of PUMA machines worldwide.
