Overview

The DN Solutions PUMA DNT 2100 is an 8-inch chuck box-way turning center that brings PUMA-class rigidity to the compact lathe segment. With an 18.5 kW (24.8 hp) spindle delivering a stout 328 Nm (242 ft-lb) of torque at up to 4,500 RPM, this machine is built for shops that need to hog material in steel and stainless without upsizing to a 10-inch platform. The box-way construction soaks up vibration on interrupted cuts where linear guide machines like the LYNX 2100 would chatter.

The PUMA DNT 2100 swings up to 400 mm (15.7 in) in diameter and turns 562 mm (22.1 in) in length. Axis travels are 230 mm (9.1 in) on X and 580 mm (22.8 in) on Z, with rapids at 24 m/min on X and 30 m/min on Z. The 12-station turret provides ample tool positions for complex part programs. At 3,700 kg (8,157 lb), it's compact enough for most shop floors while delivering the kind of cut quality that heavier machines are known for.

DN Solutions positions the DNT 2100 as their 'global standard turning center' — the 8-inch workhorse that handles everything from job shop one-offs to moderate production runs. The Fanuc 0i-Plus control with iHMI touchscreen keeps programming straightforward. This machine competes with the Haas ST-15Y and Okuma GENOS L3000-e in the 8-inch chuck class, but the box-way construction gives it an edge on cut quality in tough materials.

Strengths & Limitations

Strengths

Box-way construction delivers superior vibration damping and cut quality compared to linear guide competitors in the 8-inch chuck class
328 Nm (242 ft-lb) of spindle torque handles aggressive roughing in 4140, stainless, and alloy steels without hesitation
4,500 RPM spindle speed is faster than most box-way competitors, maintaining good performance on aluminum finishing
12-station turret provides ample tool positions for complex part programs without tool-change compromises
Compact 3,700 kg footprint brings PUMA-class rigidity without requiring the floor space of a 10-inch platform

Limitations

24 m/min X-axis rapid traverse is slower than linear guide competitors like the LYNX 2100, adding non-cutting time in complex cycles
Box ways require periodic adjustment and maintenance over high-hour production life, adding to total cost of ownership
8-inch chuck limits max part diameter compared to the 10-inch PUMA 2600 for shops that need to swing larger work
No Y-axis or live tooling on the base DNT 2100 — you'll need the DNT 2100LY or 2100LSYY for mill-turn capability

Best For

Job shops and production shops turning steel, stainless, and alloy parts in the 8-inch chuck range where cut quality matters Shops needing box-way rigidity in a compact footprint for interrupted cuts and tough materials Automotive, hydraulic, and general manufacturing running moderate volumes of precision-turned components Shops upgrading from manual or early CNC lathes who want PUMA-class performance without the size and cost of a 10-inch machine

Frequently Asked Questions

01 What does a DN Solutions PUMA DNT 2100 cost?

New PUMA DNT 2100 machines run $70,000-$110,000 depending on options. The base 2-axis version starts at the lower end, while adding live tooling, Y-axis, and sub-spindle can push past $150,000. Used Puma 2100-series machines from 2016-2022 sell in the $25,000-$50,000 range.

02 What's the difference between the PUMA DNT 2100 and the LYNX 2100?

The key difference is guideway construction. The PUMA DNT 2100 runs box ways for maximum rigidity and vibration damping, while the LYNX 2100 uses linear guides for speed. The PUMA has significantly more torque (328 Nm vs 127 Nm) and handles tougher materials better. The LYNX is faster on rapids and better for high-speed light cutting. Choose the PUMA for steel and power, the LYNX for aluminum and speed.

03 Is the PUMA DNT 2100 the same as the old Doosan PUMA 2100?

The DNT 2100 is the latest evolution of the Doosan PUMA 2100 lineage. DN Solutions (formerly Doosan Machine Tools) refined the platform with improved thermal compensation, updated controls, and enhanced rigidity. Core specs are similar, but the DNT series adds modern features and build quality improvements.

04 How does the PUMA DNT 2100 compare to the Haas ST-15?

The PUMA DNT 2100 offers significantly more torque (328 Nm vs ~160 Nm), box-way construction versus the Haas's linear guides, and generally better cut quality in tough materials. The Haas ST-15 typically costs less and has a larger US service footprint. For pure turning performance, the PUMA wins; for budget-conscious shops, the Haas is hard to beat.
