DN Solutions PUMA 4100 XLC

The DN Solutions PUMA 4100 XLC is the big-bore, extra-long-bed variant of the 4100 family, designed for shops that need maximum workholding grip and extended Z-axis reach in a single package. With a 21-inch chuck and 3,080 mm (121 in) of turning length, it's built for heavy, long parts that demand serious clamping force and plenty of room to work.

Under the covers, a 37 kW (50 hp) spindle pushes 3,280 Nm (2,419 ft-lb) of torque at speeds up to 1,500 RPM. That's a low-speed, high-torque powerplant designed for heavy material removal in carbon steel, alloy steel, and cast iron. The 21-inch chuck means you can grip large-diameter flanges, couplings, and heavy forgings without worrying about workholding limits. Box-way construction on all axes keeps the tool stable through aggressive interrupted cuts.

X-axis travel is 352 mm, Z runs 3,150 mm, and rapid traverse hits 16 m/min on X and 20 m/min on Z. The 10-station turret carries enough tooling for most production jobs. The FANUC control provides straightforward programming with conversational and G-code modes available.

At 12,900 kg (28,440 lb) and over 7 meters long, the XLC isn't a machine you'll be moving around. It needs a proper foundation, a well-planned rigging operation, and enough floor space to keep operators comfortable. But when you're turning long pipe sections, mining shafts, or heavy industrial components, this machine has the capacity and the muscle to handle the work without compromise.

The PUMA 4100 XLC fills a specific niche — long-bed, big-bore turning for heavy industry. It's the machine you spec when the parts are too long and too heavy for anything else on the floor. Specs sourced from DN Solutions published data.
