Overview

The DN Solutions PUMA 5100 XLB is the big-bore, extra-long-bed powerhouse in the 5100 family. With a 21-inch chuck, 3,042 mm (120 in) of turning length, and 45 kW (60 hp) driving 4,038 Nm (2,978 ft-lb) of torque, it's one of the most capable production lathes in DN Solutions' catalog. This is the machine you call on when your work is simultaneously too long, too heavy, and too demanding for anything else.

The spindle runs at up to 1,500 RPM with a low-speed, high-torque characteristic designed for heavy material removal. The 21-inch chuck provides the clamping force to hold large-diameter forgings and heavy workpieces securely, while over 3 meters of Z-axis travel lets you machine them end to end. Box-way construction on both axes provides the rigidity foundation that heavy turning at these scales demands.

X-axis travel is 362 mm, Z runs 3,150 mm, and rapids hit 16 m/min on X and 20 m/min on Z. The 10-station turret handles production tooling. The FANUC control provides standard programming capability with conversational and G-code modes.

At 13,050 kg (28,770 lb) and over 7 meters long, the XLB is among the heaviest machines in the PUMA lineup. That weight works for you as dampening and stability. When you're roughing a 3-meter long shaft in 4140 between centers with a 21-inch chuck driving the cut, you need every kilogram of that foundation working to kill vibration. For shops in oil and gas, marine, mining, power generation, and heavy equipment manufacturing, the 5100 XLB provides capability that few production lathes can match.

Strengths & Limitations

Strengths

21-inch chuck with 4,038 Nm torque provides massive clamping and cutting power for the heaviest work
3,042 mm (120 in) turning length handles extra-long shafts and industrial components in a single setup
45 kW (60 hp) spindle drives through tough materials without hesitation
650 mm swing accommodates large-diameter parts
13,050 kg machine mass and box-way construction deliver exceptional stability
Proven PUMA 5100 platform with strong production track record
FANUC control with universal support network

Limitations

1,500 RPM max speed limits performance on small-diameter and aluminum work
7+ meter footprint requires major floor space commitment
No live tooling or Y-axis — milling operations need a separate machine
10-station turret may limit tool variety
13,050 kg demands reinforced foundations and professional rigging
Price point puts it above many shops' capital budgets

Best For

Oil and gas shops producing drill collars, pipe sections, and long heavy components Marine and shipbuilding manufacturers turning propeller shafts and long drive shafts Mining equipment manufacturers machining large, long rollers and shafts Power generation shops turning turbine and generator shafts Heavy industry manufacturers needing both big-bore clamping and 3-meter turning reach

Frequently Asked Questions

01 What's the difference between the PUMA 5100 XLB and the 5100 XLA?

The XLB steps up to a 21-inch chuck with 4,038 Nm torque at 1,500 RPM, versus the XLA's 15-inch chuck with 3,280 Nm at 2,000 RPM. The XLB also has a more powerful 45 kW spindle vs 37 kW. Both share the same extra-long bed. Choose the XLB when you need maximum clamping force and cutting power.

02 What does a PUMA 5100 XLB cost?

New PUMA 5100 XLB machines typically run $210,000-$280,000 depending on options. This is among the most expensive machines in the PUMA lineup due to the combination of big-bore chuck and extra-long bed. Used machines sell in the $95,000-$170,000 range.

03 Can this machine handle between-centers work?

Yes. With a programmable tailstock and 3,150 mm of Z travel, the XLB excels at between-centers shaft work. A hydraulic steady rest is strongly recommended for long, slender workpieces to prevent deflection.

04 How does the 5100 XLB compare to the PUMA 700 XL II?

The PUMA 700 XL II steps up further with 900 mm swing, 5,050 mm turning length, 55 kW spindle, and 8,076 Nm torque — but at 26,000 kg and nearly 10 meters long. The 5100 XLB is the right choice when 650 mm swing and 3 meters of turning length cover your work envelope.
