Overview

The DN Solutions PUMA GT 2600 XLB pairs the extra-long bed of the XL series with a 12-inch chuck, delivering big-bore gripping capacity and extended turning length on a single platform. The 'B' designation across DN Solutions' lineup always means bigger chuck and more torque at lower RPM — and the XLB delivers exactly that.

The spindle puts out 26 kW (35 hp) with 990 Nm (730 ft-lbs) of torque at 2,500 RPM through the 12-inch chuck. That's a 35% torque increase over the XLA's 734 Nm, traded against lower top speed (2,500 vs 3,500 RPM). Max turning diameter is 460 mm (18.1 in), and turning length hits 1,573 mm (61.9 in) — slightly less than the XLA's 1,603 mm due to the larger chuck assembly. The 12-station turret provides two more tool positions than the XLA's 10-station.

Axis travels match the XLA at 265 mm on X and 1,625 mm on Z, with the same 24/30 m/min rapid traverse rates. The machine weighs 6,050 kg (13,338 lb) and stretches 4,960 mm long — about 100 mm longer and 150 kg heavier than the XLA. Those modest increases accommodate the bigger spindle and chuck assembly.

The XLB is the right choice when you're regularly chucking parts that need more gripping force than a 10-inch chuck can provide, or when you're turning larger-diameter stock where the extra torque makes a measurable difference in cycle time. The 12-station turret is also a practical advantage for complex parts. Specs sourced from DN Solutions published data.

Strengths & Limitations

Strengths

12-inch chuck with 990 Nm torque provides superior gripping capacity and turning power over the 10-inch XLA variant
1,573 mm turning length handles extended shaft work and long components on a premium GT series platform
12-station turret gives two more tool positions than the XLA, reducing tool changes on complex multi-operation parts
GT series construction with heavier castings delivers better rigidity and surface finish quality than DNT series alternatives
6,050 kg machine mass provides solid vibration damping for long-part turning operations

Limitations

2,500 RPM max spindle speed limits small-diameter finishing where high surface speed is critical
Two-axis turning only — no live tooling or C-axis for milling, cross-drilling, or off-center features
4,960 mm machine length requires dedicated floor space and may need crane access for workpiece loading on long parts
Slightly less turning length than the XLA (1,573 mm vs 1,603 mm) due to the larger chuck assembly
Price premium of $10-15K over the XLA may not be justified if your parts don't need the 12-inch chuck

Best For

Shops turning larger-diameter long parts that need more chucking force than a 10-inch chuck provides Heavy equipment manufacturers producing large-bore shafts, pins, and structural components in the 1-1.5 meter length range Pipe and tube manufacturers turning OD features, threads, and connections on large-diameter tubular stock Oil and gas shops that need the torque for aggressive roughing on long, heavy steel and alloy components Production environments where the 12-station turret eliminates tool change interruptions on complex parts

Frequently Asked Questions

01 When should I choose the XLB over the XLA?

Choose the XLB when your parts regularly require a chuck larger than 10 inches, when you need the extra torque (990 Nm vs 734 Nm) for aggressive cuts on larger diameters, or when you need 12 tool stations instead of 10. If your parts fit in a 10-inch chuck and you value higher spindle speed, the XLA is the better choice.

02 How much does a DN Solutions PUMA GT 2600 XLB cost?

New GT 2600 XLB machines typically price between $130,000 and $190,000. The 12-inch chuck and higher-torque spindle add a modest premium over the XLA variant. Common options including tailstock, steady rest, chip conveyor, and high-pressure coolant push toward the upper end.

03 Can the GT 2600 XLB handle heavy interrupted cuts?

Yes. The GT series' heavier construction and 6,050 kg mass provide good stability for interrupted cutting. The 990 Nm of torque maintains cutting performance through interruptions better than lower-torque machines. For extreme interrupted cutting on large forgings, the GT 3100 series may be more appropriate.

04 What bar capacity does the 12-inch chuck XLB offer?

The big-bore 12-inch chuck spindle accommodates larger bar stock than the 10-inch XLA. Exact bar capacity depends on the drawbar and collet configuration ordered. For bar feeder production of larger-diameter material, the XLB's bigger bore is a practical advantage.
