Overview

The DN Solutions PUMA 5100 XLMB is the ultimate combination in the PUMA turning lineup: 21-inch chuck, 26-inch swing, extra-long bed, and the most powerful spindle in the 5100 series. At 45 kW (60 hp) and 2,958 Nm (2,182 ft-lb) of torque, it's built for the heaviest, longest, largest-diameter turning work a horizontal lathe can handle.

Max turning length reaches 3,028 mm (119 in) with the 21-inch chuck installed, giving you nearly 10 feet of workable length at up to 650 mm (26 in) diameter. This is the machine for power generation turbine shafts, large marine propulsion components, mining crusher shafts, and oil country equipment that simply won't fit in anything smaller.

The spindle runs to 1,500 RPM max — the trade-off for maximum chuck size and torque. On a 500 mm diameter part, that's still over 2,300 SFM, well within productive cutting parameters for steel and iron. The 21-inch chuck provides the clamping authority needed for heavy, irregular workpieces where secure grip is a safety and quality requirement.

Z-axis travel is 3,150 mm (124 in) with 362 mm (14 in) on X. The 12-station turret with 4,000 RPM live tooling allows secondary operations on parts that would take a forklift to move to a mill. Box-way construction across the full bed length ensures consistent rigidity and accuracy regardless of where you're cutting.

At 13,200 kg (29,101 lb), this is the heaviest machine in the PUMA 5100 series. That mass translates directly to stability and vibration absorption during heavy cutting. The FANUC 0i-TF Plus control is standard, and most shops running this class of equipment program in G-code with parametric macros for repetitive long-part features.

Strengths & Limitations

Strengths

Maximum capability in the 5100 series: 21" chuck, 26" swing, 119" turning length, and 60 hp spindle
2,958 Nm of torque handles the most aggressive roughing in tough materials on large-diameter stock
3,028 mm max turning length accommodates very long shafts and rollers in a single setup
13,200 kg machine mass provides outstanding vibration damping for heavy interrupted cuts
Live tooling eliminates secondary setups on massive parts that are impractical to re-fixture
Box-way construction maintains accuracy across the full extra-long bed length

Limitations

1,500 RPM spindle speed is the lowest in the 5100 series — not suitable for high-speed small-diameter work
13,200 kg is the heaviest PUMA 5100 variant, requiring the most substantial foundation and rigging
Largest footprint in the series demands dedicated floor space for the extra-long bed
Highest price in the 5100 lineup reflects the maximum spindle, chuck, and bed length configuration
21-inch chuck tooling investment is significant, and jaw sets are expensive

Best For

Power generation OEMs machining the largest turbine shafts, generator rotors, and hydro-power components Marine and shipbuilding shops producing large propeller shafts, rudder stocks, and stern tube components Mining equipment manufacturers turning crusher mainshafts, large conveyor rollers, and heavy axles Oil and gas companies producing large-bore drill collars, risers, and subsea equipment components Steel and metals industry shops machining calendar rolls, process rolls, and large-diameter mandrels Any heavy industry application requiring maximum turning diameter, length, and clamping capacity

Frequently Asked Questions

01 Is the PUMA 5100 XLMB the largest lathe DN Solutions makes?

No. The PUMA 700 and 800 series have larger swing capacity (900 mm / 35 in) with even bigger chucks (24" and 32"). The PUMA 1000 handles 1,000 mm diameter work. But the 5100 XLMB is the largest in the PUMA 5100 family and offers the best combination of swing, length, and live tooling in its class.

02 How does loading work on a machine this size?

Most shops use an overhead bridge crane to load workpieces into the chuck. Parts running on the XLMB typically weigh hundreds to thousands of kilograms. Some shops integrate a gantry robot for semi-automated loading of repetitive parts, but crane loading with manual chuck clamping is the standard approach.

03 Can I get a programmable tailstock on the XLMB?

Yes. A programmable hydraulic tailstock is a standard option on the PUMA 5100 XL series. It's essential for long shaft work between centers, providing consistent thrust pressure and eliminating manual adjustment between parts. The tailstock can be positioned along the full bed length.

04 What type of chip conveyor is recommended?

A hinged belt chip conveyor is standard for the heavy chips this machine produces. For cast iron work, a magnetic conveyor option may be available. The high material removal rates on this machine mean chip management is critical — a properly sized conveyor and chip hopper are essential for uninterrupted production.
