Overview

The DN Solutions PUMA DNT 2600M is a mid-size heavy-duty turning center built on the current DNT platform with a 10-inch chuck, driven tooling, and box-way construction that targets production facilities processing steel, stainless, and alloy parts in the 250-500 mm diameter range. It sits a step above the DNT 2100M in turning capacity and a step below the large-format DNT 3100M, making it the most broadly applicable machine in the DNT M series for job shops and contract manufacturers.

The main spindle carries an A2-8 nose driven by a 22 kW (30 hp) motor producing 398 Nm (293 ft-lb) of torque at speeds up to 3,500 RPM. The heavier torque rating relative to the 2100M reflects the larger workholding — the 10-inch chuck and higher cutting forces required when turning larger-diameter forgings, castings, and bar stock. The 82 mm (3.2 in) through-bore handles standard bar sizes used in most production turning applications.

Axis travels extend to 260 mm (10.2 in) on X and 830 mm (32.7 in) on Z, with rapids at 30 m/min on X and 24 m/min on Z. The 12-station BMT 65 live-tool turret operates driven tools at up to 3,500 RPM with 5.5 kW (7.5 hp), stepping up from the 2100M's BMT 45 interface to handle heavier driven tool loads on larger workpieces. Static tools for heavy roughing remain fully supported.

DN Solutions fits the PUMA DNT 2600M with the Fanuc 0i-TF Plus control and 15-inch iHMI touchscreen as standard, with Siemens 828D available as an option. The iHMI platform supports EZ Guide i conversational programming alongside full G-code, allowing mixed-skill operator teams to run the machine productively without specialized programming knowledge.

Pricing for the DNT 2600M runs $120,000-$165,000 new, positioning it between the Haas ST-20Y and DMG Mori NLX 2500 in cost while offering heavier box-way construction and more torque than either. The machine is well-suited to shops that have outgrown 8-inch chuck turning but don't need the size and cost of the DNT 3100M platform.

Strengths & Limitations

Strengths

Box-way construction absorbs vibration during heavy interrupted cuts in forgings, castings, and tough alloys better than linear guide alternatives
398 Nm (293 ft-lb) spindle torque enables aggressive roughing passes on large-diameter steel and stainless parts
BMT 65 live-tool turret with 7.5 hp driven tool power handles heavier milling loads than the lighter BMT 45 interface on smaller DNT models
10-inch chuck and 481 mm (19 in) maximum turning diameter cover the majority of mid-size production turning requirements
82 mm through-bore accommodates standard bar stock sizes with bar feeder integration for unattended production
Fanuc 0i-TF Plus with iHMI offers industry-standard control familiarity with conversational fallback for less experienced operators

Limitations

No Y-axis on the standard DNT 2600M — off-center and contoured milling requires the Y-axis variant or a different machine class
3,500 RPM spindle speed is limiting for small-diameter aluminum finishing where 5,000+ RPM produces better surface finish
5,600 kg (12,346 lb) weight demands proper floor preparation and limits repositioning flexibility
Box-way maintenance costs accumulate over high-cycle production life compared to linear guide designs
Live tooling at 3,500 RPM is lower than some competitors' driven tool speeds, which can affect cycle time on small-diameter driven tool work

Best For

Production shops turning medium-to-large steel, stainless, and alloy parts in the 10-inch chuck range with occasional milling needs Job shops processing flanges, hydraulic cylinder bodies, valve bodies, and shafts where rigidity determines part quality Automotive, oil and gas, and industrial equipment manufacturers running high volumes of rotational components Shops that need driven tooling for cross-holes, slots, and keyways but don't require full Y-axis mill-turn capability Operations standardized on Fanuc or Siemens controls who want a consistent programming environment across turning equipment

Frequently Asked Questions

01 How does the PUMA DNT 2600M differ from the PUMA 2600?

The PUMA DNT 2600M is the current-generation successor to the older PUMA 2600 and PUMA GT 2600. The DNT designation indicates the updated platform with improved thermal compensation, the Fanuc 0i-TF Plus control with iHMI touchscreen, and refined spindle and turret specifications. The DNT 2600M adds live tooling as standard where the base PUMA 2600 was a 2-axis machine. Core turning envelope dimensions are similar.

02 Can the PUMA DNT 2600M handle shaft turning with a tailstock?

Yes. A programmable tailstock is available as an option, supporting shaft work up to the machine's 830 mm (32.7 in) turning length. The tailstock quill provides center support for long, slender parts where chuck clamping alone would result in deflection. This is a common configuration for shops turning shafts for pumps, motors, and gearboxes.

03 What is the practical milling capacity of the live-tool turret?

The BMT 65 turret drives tools at up to 3,500 RPM with 5.5 kW (7.5 hp). This is adequate for drilling and tapping in steel, light face milling, slotting, and keyway cutting on medium-size turned parts. It is not a substitute for a dedicated machining center on parts requiring heavy milling stock removal or complex 3D contouring.

04 What does a new PUMA DNT 2600M cost?

New PUMA DNT 2600M machines typically sell in the $120,000-$165,000 range depending on options selected — tailstock, chip conveyor, parts catcher, bar feeder interface, and tooling packages are the most common additions that push price toward the upper end. Siemens 828D control also carries a premium over standard Fanuc configuration.

05 How does the DNT 2600M compare to the DMG Mori NLX 2500?

Both are capable 10-inch class turning centers with live tooling. The PUMA DNT 2600M offers heavier box-way construction and more torque, which benefits heavy roughing in steel and stainless. The DMG Mori NLX 2500 offers faster rapid traverse and a broader ecosystem of automation options. Price-wise, the NLX 2500 typically costs $20,000-$40,000 more depending on configuration. For pure turning power at the price, the PUMA DNT 2600M is the stronger value.
