Overview
The DN Solutions PUMA 4100 XLMA is the extra-long bed variant of the 4100 series, built for shops that need to turn long shafts, rollers, and tubular components up to 3,100 mm (122 in) between centers. With a 12-inch chuck and 37 kW (50 hp) spindle pushing 1,024 Nm (755 ft-lb) of torque, this machine doesn't flinch at heavy roughing passes in alloy steel or stainless. It's the kind of lathe you bring in when your current machines can't handle the length.
The XLMA designation means extra-long bed with milling capability. You've got a 12-station turret with 4,000 RPM live tooling, so cross-drilling, keyway milling, and flat machining happen right on the lathe without a secondary setup on a mill. That's a real time-saver when you're running one-off or low-volume long parts that need secondary features.
Axis travels are generous: 352 mm (14 in) on X and a full 3,150 mm (124 in) on Z. Rapid traverse runs at 16 m/min on X and 20 m/min on Z. Those aren't blazing rapids, but on a machine this size, you're not chasing cycle time on small parts — you're after capability and rigidity. The box-way construction delivers exactly that, holding tolerance over the full length of the bed without deflection.
The FANUC 0i-TF Plus control is standard across the PUMA lineup. It's familiar to most operators, well-supported by service techs everywhere, and handles the conversational-to-G-code workflow that production shops depend on. Thermal compensation and servo tuning have been refined over multiple PUMA generations.
At roughly 12,050 kg (26,566 lb), the XLMA needs serious floor prep and rigging. This isn't a machine you're moving around the shop on a whim. But for dedicated long-part production — think power generation shafts, mining rollers, oil country tubular work — it's purpose-built and proven. Specs sourced from DN Solutions published data.

Strengths & Limitations
Strengths
- 3,100 mm (122 in) max turning length handles long shafts, rollers, and tubular components that won't fit on standard-bed lathes
- 37 kW (50 hp) spindle with 1,024 Nm of torque powers through heavy roughing in alloy steel and stainless without bogging down
- 12-station turret with 4,000 RPM live tooling eliminates secondary mill setups for cross-drilling, flats, and keyways
- Box-way construction maintains rigidity and tolerance over the full 3+ meter bed length
- FANUC 0i-TF Plus control is the industry standard with broad operator familiarity and service support
- 12-inch chuck with A2-11 spindle nose accommodates a wide range of workholding options for large-diameter parts
Limitations
- 12,050 kg machine weight demands heavy-duty floor preparation and professional rigging for installation
- 16 m/min X-axis rapids are slower than smaller lathes, though that's typical for machines in this size class
- 3,000 RPM max spindle speed limits high-speed finishing on small diameters in aluminum
- Long bed means a large footprint that many shops can't accommodate without rearranging their layout
- Price premium over the standard PUMA 4100 MA is significant for the extra bed length

Frequently Asked Questions
01
The A, B, and C designations refer to chuck size and spindle configuration. The XLMA runs a 12-inch chuck at 3,000 RPM with 1,024 Nm torque. The XLMB uses a 15-inch chuck at 2,000 RPM with 1,611 Nm torque. The XLMC runs a 21-inch chuck at 1,500 RPM with 2,432 Nm torque. All three share the same extra-long 3,150 mm Z-axis travel.
02
The 5100 XLMA is a step up in swing capacity — 650 mm (26 in) max turning diameter versus 550 mm (22 in) on the 4100. The 5100 also gets a 15-inch chuck minimum and higher torque. If your parts exceed 22 inches in diameter, you need the 5100. For parts under that size, the 4100 saves money and floor space.
03
While technically possible, the XLMA's 3+ meter bed length and 12-inch chuck are really designed for chucking work or shaft work between centers. Most shops using this machine are holding parts in the chuck with tailstock support, not feeding bar stock. For bar work, the PUMA 2600 or LYNX series is a better fit.
04
At 12,050 kg, you'll need a reinforced concrete foundation typically 300-400 mm thick with proper leveling pads. DN Solutions provides foundation drawings with the machine order. Most dealers will do a site survey before delivery to confirm the floor can handle the load.
05
The 12-station turret supports 4,000 RPM driven tools for cross-drilling, tapping, milling flats, cutting keyways, and machining hexes. You can do off-center work with C-axis interpolation. It won't replace a full VMC, but it handles common secondary operations that would otherwise require a second setup.
