Overview

The DN Solutions PUMA 4100 XLB is an extra-long-bed variant of the proven 4100 platform, purpose-built for shops that need to turn long shafts, rollers, and cylindrical components that won't fit in a standard-bed machine. With 3,120 mm (123 in) of turning length and a 15-inch chuck, it's the kind of lathe you bring in when your work keeps hanging off the end of a shorter machine.

The spindle delivers 35 kW (47 hp) and 2,379 Nm (1,755 ft-lb) of torque through an A2-11 nose, topping out at 2,000 RPM. That's a torque-forward design aimed squarely at heavy stock removal in carbon steel, alloy steel, and cast iron. You're not chasing RPM here — you're pushing metal. The box-way construction on all axes soaks up chatter on interrupted cuts and keeps the tool planted where it needs to be.

X-axis travel runs 352 mm with Z at a generous 3,150 mm, and rapids hit 16 m/min on X and 20 m/min on Z. The 10-station turret handles OD and ID tooling for most production jobs without needing to swap holders mid-cycle. The FANUC control gives you everything from conversational programming to full G-code, and every Fanuc-trained operator on your floor already knows their way around it.

At 12,400 kg (27,337 lb), you'll need solid floor prep and probably a rigger with a plan. But that mass is working for you — it translates directly into stability and vibration damping when you're roughing long parts between centers. The PUMA 4100 XLB fills a gap that smaller lathes can't touch: long, heavy turning work where rigidity and reach both matter. Specs sourced from DN Solutions published data.

Strengths & Limitations

Strengths

3,120 mm (123 in) turning length handles long shafts, rollers, and pipe components that standard-bed machines can't accommodate
Box-way construction on all axes delivers superior vibration damping for heavy interrupted cuts on long workpieces
35 kW spindle with 2,379 Nm of torque handles aggressive roughing in tough materials without stalling
15-inch chuck provides solid workholding for mid-to-large diameter parts
12,400 kg machine weight contributes to stability during heavy cuts on extended parts
FANUC control is the industry standard — operators, service techs, and parts are readily available
Proven PUMA 4100 platform with strong track record in production turning environments

Limitations

2,000 RPM spindle speed ceiling limits performance on small-diameter aluminum work where higher RPM improves surface finish
7+ meter footprint requires significant floor space and careful shop layout planning
No live tooling or Y-axis on this variant — milling operations require a second setup on a different machine
10-station turret may feel limiting on complex jobs that need more tool variety versus the 12-station option on other models
12,400 kg weight demands reinforced flooring and professional rigging for installation

Best For

Shops turning long shafts, rollers, and cylindrical components over 2 meters in length Oil and gas manufacturers producing drill collars, pipe sections, and long tubular parts Power generation and heavy equipment shops machining turbine shafts and drive components Job shops that regularly handle long parts and need a dedicated long-bed turning platform Manufacturers in mining, marine, and heavy industry requiring heavy-duty long-reach turning Shops replacing older engine lathes with modern CNC capability for long part work

Frequently Asked Questions

01 What's the difference between the PUMA 4100 XLB and the PUMA 4100 LB?

Both use a 15-inch chuck and the same spindle platform, but the XLB adds roughly 1,000 mm more Z-axis travel (3,150 mm vs 2,155 mm). The XLB turns parts up to 3,120 mm long versus 2,092 mm on the LB. The XLB is about 1,000 kg heavier and 1.25 meters longer. Choose the XLB when your work consistently exceeds 2 meters in length.

02 What does a PUMA 4100 XLB cost?

New PUMA 4100 XLB machines typically run $180,000-$240,000 depending on options like programmable tailstock, chip conveyor, steady rest, and tool setter. Used machines from recent model years sell in the $80,000-$140,000 range depending on hours and condition.

03 Can the PUMA 4100 XLB handle between-centers turning?

Yes. With 3,150 mm of Z-axis travel and a programmable tailstock option, the XLB handles long shaft work between centers. A hydraulic steady rest is available for supporting long, slender workpieces prone to deflection.

04 What materials can the PUMA 4100 XLB handle?

The 35 kW spindle and 2,379 Nm of torque handle carbon steel, alloy steel, stainless, cast iron, and other ferrous materials without issue. The box-way design is particularly strong on interrupted cuts and hard materials where rigidity matters most.

05 Is the FANUC control easy to learn?

FANUC controls are the most widely used CNC controls in the world. Most operators and programmers are already familiar with FANUC G-code and conversational programming. Service techs and replacement parts are readily available through a large dealer network.
