Overview
The DN Solutions PUMA 5100 XLMA combines the 5100's 26-inch swing capacity with an extra-long bed stretching to 3,150 mm (124 in) of Z-axis travel. It's the machine you need when parts are both large in diameter and long — think power generation shafts, marine propeller shafts, process industry rollers, and large hydraulic cylinder rods.
With a 15-inch chuck and 37 kW (50 hp) spindle pushing 2,432 Nm (1,794 ft-lb) of torque at up to 2,000 RPM, the XLMA handles heavy roughing passes on large-diameter, long workpieces without compromise. The max turning length of 3,068 mm (121 in) means you can machine parts nearly 10 feet long in a single setup — a capability that eliminates re-chucking errors on long, precision-ground shafts.
The 12-station turret runs live tools at 4,000 RPM for secondary operations like cross-drilling, keyway milling, and tapping. On parts this size, pulling them out for a secondary mill setup is a serious production bottleneck, so having milling capability on the lathe saves hours of handling time per part.
X-axis provides 362 mm (14 in) of cross travel to accommodate the full 650 mm turning diameter. Rapids run 16 m/min on X and 20 m/min on Z. Box-way construction across the full 3+ meter bed maintains rigidity from chuck to tailstock. At 12,700 kg (27,999 lb), this is a substantial piece of iron that needs a proper foundation.
The FANUC 0i-TF Plus control is standard — same as every other PUMA in the lineup. Most shops running this class of machine will have experienced operators programming in G-code with custom macros for repetitive shaft features. Steady rest support is available for slender workpieces that need mid-span support. Specs sourced from DN Solutions published data.

Strengths & Limitations
Strengths
- 3,068 mm max turning length with 26-inch swing — handles both large-diameter and extra-long workpieces
- 2,432 Nm of torque provides aggressive roughing capability on large-diameter stock
- 15-inch chuck balances workholding capacity with reasonable spindle speed (2,000 RPM)
- Live tooling at 4,000 RPM eliminates secondary setups on large parts that are impractical to move
- Box-way construction maintains accuracy across the full 3+ meter bed length
- 12,700 kg machine mass absorbs vibration from heavy interrupted cuts on rough castings
Limitations
- Extra-long bed requires significant floor space — plan for an 8-9 meter machine length footprint
- 12,700 kg requires heavy-duty foundation preparation and specialized rigging
- 2,000 RPM spindle speed limits surface speed on small-diameter features
- Higher price point than the LMA variant due to the additional bed length and machine weight
- Rapids at 16/20 m/min mean longer non-cutting time during Z-axis traverses on long parts

Frequently Asked Questions
01
The 5100 XLMA swings 650 mm (26 in) versus 550 mm (22 in) on the 4100. It also delivers much more torque — 2,432 Nm vs 1,024 Nm with the 15-inch chuck. Both have similar Z-axis travel. If your parts exceed 22 inches in diameter, you need the 5100. The 4100 saves money and weight for smaller-swing work.
02
DN Solutions offers hydraulic fixed and follow steady rests for the PUMA 5100 XL series. These are essential for long, slender shafts where the length-to-diameter ratio would cause deflection during cutting. The steady rests mount to the bed and can be positioned along the full Z-axis travel.
03
With proper tooling, workholding, and steady rest support, the PUMA 5100 XLMA can achieve finish turning surface quality in the 0.8-1.6 Ra range on many materials. The box-way construction and machine mass help minimize vibration. For true grinding-quality finishes, a dedicated grinder is still recommended.
04
Maximum part weight depends on the specific machine configuration and chuck/tailstock setup. Contact DN Solutions for the rated capacity. For very heavy parts, additional bed support and spindle bearing pre-load options may be recommended. Most shops use overhead cranes for loading workpieces on machines in this size class.
