Overview
The DN Solutions PUMA DNT 2100 B is a compact 2-axis horizontal turning center built for high-volume production of small-to-medium parts. The 'B' suffix denotes the big-bore variant with a 10-inch chuck, giving it more gripping capacity than the standard DNT 2100's 8-inch chuck while keeping the same compact footprint. It's the workhorse choice for shops turning parts up to 400 mm diameter.
The main spindle delivers 18.5 kW (25 hp) at 3,500 RPM with 403 Nm (297 ft-lbs) of torque. That's a well-balanced combination for general-purpose turning of steel, stainless, aluminum, and cast iron in the 2-8 inch diameter range. The 10-inch chuck provides a secure grip on larger bar stock and chucked blanks that an 8-inch chuck would struggle with.
Axis travels of 230 mm on X and 581 mm on Z keep the work envelope tight but adequate for parts up to 550 mm (21.7 in) turning length. Rapid traverse runs 24 m/min on X and 30 m/min on Z — fast enough for production work. The 12-station turret provides ample tool positions for multi-operation parts. At just 3,800 kg (8,378 lb) and 2,945 mm long by 1,664 mm wide, this is one of the most compact machines in the PUMA lineup.
The DNT series positions as DN Solutions' value line — delivering reliable turning performance at a price point below the GT and TT series. For shops running second and third shifts on bread-and-butter turning work, the DNT 2100 B delivers the throughput and reliability that pays the bills without the cost of features you don't need.

Strengths & Limitations
Strengths
- 10-inch chuck provides more workholding capacity than the standard 8-inch DNT 2100, handling larger blanks and forgings
- Compact 2,945 mm x 1,664 mm footprint fits into tight shop layouts and makes efficient use of floor space
- 12-station turret handles multi-operation parts without the tool limitations of smaller turrets
- 3,500 RPM spindle with 403 Nm torque balances speed and power for general-purpose turning of most common materials
- Competitive price point in the $75K-$120K range makes it accessible for smaller shops and startups
- 3,800 kg weight keeps foundation requirements minimal while maintaining adequate rigidity for production turning
Limitations
- Two-axis only — no live tooling, C-axis, or milling capability for off-center features
- 550 mm max turning length limits shaft work; step up to the DNT 2100 L or DNT 2600 for longer parts
- 18.5 kW spindle power can be limiting for aggressive roughing on larger-diameter stainless and heat-resistant alloys
- DNT series lacks some of the premium features found on the GT series, including box-way options and higher-rigidity construction

Frequently Asked Questions
01
The 'B' designation means big bore with a 10-inch chuck vs the standard 8-inch chuck. The B variant also has more torque (403 Nm vs the standard model's lower figure). Choose the B when you regularly chuck parts larger than 8 inches or need the additional torque for heavier cuts.
02
New DNT 2100 B machines typically price between $75,000 and $120,000. Base machines with standard turret and no options start at the lower end. Adding parts catchers, chip conveyors, bar feeder interfaces, and high-pressure coolant push toward $120K. This is one of the most affordable CNC lathes in the PUMA lineup.
03
Yes. The DNT 2100 B is bar-feeder ready and commonly paired with magazine-style bar feeders for unattended production. Bar capacity through the spindle depends on the specific configuration, but the 10-inch chuck variant accommodates larger bar stock than the standard 8-inch model.
04
The GT 2600 is a step up in every dimension: larger work envelope (460 mm diameter, 658+ mm length), more power (26 kW), and premium construction features. The DNT 2100 B is the value choice for smaller parts. If your work regularly exceeds 400 mm diameter or 550 mm length, the GT 2600 is the better fit.
