Our best estimate for a cnc lathes / turning center in this class — not a quote from DN Solutions. Configuration moves it a long way.
Overview
The DN Solutions PUMA 4100 XLMC is a long-bed turning center with a 21 in chuck and driven tools: 3,150 mm (124 in) of Z travel, a 1,500 rpm spindle with 2,432 N·m (1,794 ft-lb), and a 12-station turret whose live tools run to 4,000 rpm. At 13,050 kg (28,770 lb) it is also a machine to plan the floor around.
Start with the installation, because it constrains everything else. The listed size is 7,024 mm (277 in) in length, 2,276 mm (90 in) in width and 2,335 mm (92 in) in height. Parts near the 3,028 mm (119 in) maximum turning length and the 550 mm (22 in) maximum turning diameter will be crane loads, so the lifting path over the bed deserves as much attention as the foundation.
The spindle is rated 37 kW (50 hp). The two-axis PUMA 4100 C shares the 21 in chuck, the 1,500 rpm limit and the 37 kW (50 hp) rating, but lists 3,280 N·m (2,419 ft-lb), so the XLMC gives up about 26% of that torque. Its 2,432 N·m (1,794 ft-lb) is the same figure DN Solutions lists for the PUMA 5100 LYA, a 15 in machine that runs to 2,000 rpm. In practice this is a large-chuck machine for medium cuts and parts finished in one setup, not the strongest rougher in the family.
Driven tools at 4,000 rpm cover drilling, tapping and milling along the shaft. The table lists X travel of 352 mm (14 in) and Z travel, with no Y axis, and it gives no power figure for the live tools. Rapid traverse is 16 m/min (630 ipm) in X and 20 m/min (787 ipm) in Z.

Strengths & Limitations
Strengths
- 21 in chuck and 4,000 rpm live tools on the same machine, with a 12-station turret
- 2,432 N·m (1,794 ft-lb) of spindle torque from 37 kW (50 hp)
- 3,150 mm (124 in) of Z travel; maximum turning length 3,028 mm (119 in)
- Live tools let heavy parts be milled and drilled where they sit, avoiding a second crane setup
Limitations
- About 26% less spindle torque than the 3,280 N·m (2,419 ft-lb) of the two-axis PUMA 4100 C
- 1,500 rpm top speed restricts surface speed on small turned diameters
- No Y-axis travel in the table, and no live tool power or torque figure
- 13,050 kg (28,770 lb) on 7,024 × 2,276 mm (277 × 90 in) of floor needs a prepared foundation

Frequently Asked Questions
01
The PUMA 4100 C is a two-axis machine with a 10-station turret, 1,105 mm (44 in) of Z travel, a 1,002 mm (39 in) maximum turning length and 3,280 N·m (2,419 ft-lb) of torque. The XLMC has a 12-station turret with 4,000 rpm live tools, 3,150 mm (124 in) of Z travel, a 3,028 mm (119 in) maximum turning length and 2,432 N·m (1,794 ft-lb). Both use a 21 in chuck, 1,500 rpm and 37 kW (50 hp).
02
DN Solutions lists a machine weight of 13,050 kg (28,770 lb). For comparison, the short-bed PUMA 4100 C weighs 10,450 kg (23,038 lb). The figure is the machine's own weight, so the workpiece and anything else standing on the slab come on top when the foundation is specified.
03
The main spindle is listed at a maximum of 1,500 rpm and the live tools at 4,000 rpm. The low main spindle speed fits the 21 in chuck and large-diameter work. On a part near 550 mm (22 in) it is ample, while small journals on the same shaft will be turned slower than ideal.
04
The table lists no Y travel for this model, only 352 mm (14 in) of X and 3,150 mm (124 in) of Z. Driven tools therefore work on the plane through the spindle centerline: cross holes, keyways and end-face drilling are within reach, while a flat or pocket offset from the centerline is not something the listed travels support.
