Overview
The DN Solutions PUMA DNT 2100M is a heavy-duty 8-inch chuck turning center with driven tooling that targets job shops and production facilities running medium-size turned parts in steel, stainless, and high-temp alloys. The DNT series represents DN Solutions' current-generation platform, built on rigid box-way construction and refined with improved thermal stability over the older PUMA GT lineage it replaces.
The main spindle swings an A2-6 nose driven by a 18.5 kW (25 hp) motor producing 310 Nm (229 ft-lb) of torque at up to 4,500 RPM. That speed ceiling lets the machine handle smaller-diameter aluminum and brass work alongside the steel-heavy jobs where box-way lathes traditionally excel. The 65 mm (2.6 in) through-bore accommodates bar stock for automated production, and the 8-inch chuck covers parts up to 400 mm (15.7 in) in swing.
Axis travels run 185 mm (7.3 in) on X and 600 mm (23.6 in) on Z, with rapids at 30 m/min on X and 24 m/min on Z. The 12-station BMT 45 live-tool turret accommodates both static and driven tools at up to 4,000 RPM, giving the machine mill-drill capability for cross-holes, flats, and keyways without a secondary operation. Driven tool power is 3.7 kW (5 hp).
The control is FANUC 0i-TF Plus with DN Solutions' 15-inch iHMI touchscreen interface. The iHMI layers conversational EZ Guide programming over standard G-code, which keeps setup time low for operators transitioning from manual or older CNC equipment. Siemens 828D is available as an option for shops standardized on Siemens.
Pricing runs $100,000-$140,000 new with standard options. The PUMA DNT 2100M competes with the Haas ST-15Y and Mazak Quick Turn Nexus 150 II MY in this chuck class. Its box-way rigidity and higher torque give it an edge on heavy roughing; the competition may edge ahead on high-speed aluminum finishing. A programmable tailstock and chip conveyor are the most common add-ons.

Strengths & Limitations
Strengths
- Box-way construction provides exceptional rigidity and vibration damping for interrupted cuts in tough alloys and stainless steel
- 4,500 RPM spindle extends usable range into aluminum and brass work beyond what older heavy-duty lathes could manage
- 12-station live-tool turret with 4,000 RPM and 5 hp eliminates secondary mill-drill operations for cross-holes, flats, and keyways
- Fanuc 0i-TF Plus with iHMI touchscreen supports both conversational and G-code programming with minimal operator retraining
- DNT platform introduces improved thermal compensation over prior PUMA GT generation for tighter tolerance consistency across long runs
- Compact footprint relative to turning capacity makes it accessible in shops with limited floor space
Limitations
- No Y-axis on the standard 2100M — off-center milling capability requires upgrading to a Y-axis variant
- 65 mm (2.4 in) bar capacity is modest for shops running larger-diameter bar stock production
- 3.7 kW (5 hp) driven tooling is adequate for light milling but not well-suited for heavy side-milling operations
- Box-way maintenance (periodic scraping and adjustment) adds long-term cost versus linear guide alternatives
- 4,500 RPM spindle ceiling falls short for high-speed finishing of small aluminum parts where 6,000+ RPM is preferable

Frequently Asked Questions
01
The PUMA DNT 2100M is the current-generation replacement for the PUMA GT 2100. Key improvements include updated thermal compensation for better long-run accuracy, the new Fanuc 0i-TF Plus control with 15-inch iHMI touchscreen, and revised spindle and turret specifications. Core construction remains box-way, but the DNT platform refines tolerancing and usability over the GT series.
02
Yes. The 65 mm (2.4 in) through-bore accepts bar stock up to that diameter, and the machine is designed for bar feeder integration. Most standard short and long bar feeders from suppliers like LNS and Iemca can be fitted. For larger bar capacity, the PUMA DNT 2600M offers a bigger bore.
03
The PUMA DNT 2100M delivers more spindle torque and heavier box-way construction than the Haas ST-15Y, which uses linear guides. The Haas offers a Y-axis and sub-spindle as standard on the SY variant. For heavy roughing in steel, the PUMA holds an advantage. For flexibility with lighter materials and sub-spindle work, the Haas SY configuration may be preferable.
04
The live-tool turret supports up to 4,000 RPM with 3.7 kW (5 hp) of driven tool power. This is sufficient for drilling, tapping, and light-to-medium milling of cross-holes, flats, slots, and keyways in steel and aluminum. For heavy face milling or large-diameter circular milling, a dedicated mill-turn center would be more appropriate.
05
Yes. DN Solutions offers the Siemens 828D control as an alternative to the standard Fanuc 0i-TF Plus. Shops standardized on Siemens across their turning and machining centers can specify the 828D to maintain consistent programming and maintenance environments.
