Overview
The DN Solutions PUMA 4100 B is a two-axis heavy turning center with a 15 in chuck, 550 mm (22 in) of maximum turning diameter and 1,042 mm (41 in) of maximum turning length. Its spindle is rated 35 kW (47 hp) and 2,379 N·m (1,755 ft-lb) with a 2,000 rpm top speed, and the turret has 10 stations.
DN offers the two-axis PUMA 4100 with three chuck sizes, 12, 15 and 21 in, and the B is the middle one. The steps between them are large. The PUMA 4100 LA, with the 12 in chuck, lists 3,000 rpm and 1,584 N·m (1,168 ft-lb). The PUMA 4100 C, with the 21 in chuck, lists 1,500 rpm, 37 kW (50 hp) and 3,280 N·m (2,419 ft-lb). At 2,379 N·m (1,755 ft-lb) and 2,000 rpm this model sits between them. It has the torque for deep roughing cuts in steel across most of its 550 mm (22 in) turning diameter, without the 1,500 rpm ceiling of the PUMA 4100 C, which makes smaller diameters slow to finish.
Travels are 352 mm (14 in) in X and 1,105 mm (44 in) in Z, with rapids of 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z. Those are moderate rates. On heavy turning, where most of the cycle is spent in the cut, they matter less than they would on a small production lathe.
The table shows no live-tool speed and no Y travel, so this is a turning-only machine: a drilled bolt pattern or a milled flat is a second operation elsewhere. For shafts longer than 1,042 mm (41 in), the PUMA 4100 LB carries the same spindle rating on 2,155 mm (85 in) of Z travel and turns 2,092 mm (82 in).
Machine weight is 9,950 kg (21,936 lb), and DN lists 4,654 × 2,056 × 2,194 mm (183 × 81 × 86 in) as length, width and height.

Strengths & Limitations
Strengths
- 2,379 N·m (1,755 ft-lb) of spindle torque from 35 kW (47 hp) on a 15 in chuck
- 2,000 rpm top speed, against 1,500 rpm on the 21 in PUMA 4100 C
- 550 mm (22 in) of turning diameter with 352 mm (14 in) of X travel
- 1,042 mm (41 in) of turning length, the longer figure of the two short-bed models compared here: the PUMA 4100 C turns 1,002 mm (39 in)
- 9,950 kg (21,936 lb) of machine weight behind the cut
Limitations
- No live-tool speed or Y travel in the table: milling and cross-drilling need another machine
- 10 turret stations, where the PUMA 4100 LA lists 12
- Rapids of 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z are modest for short-cycle work
- Torque is below the 3,280 N·m (2,419 ft-lb) of the PUMA 4100 C for the largest, heaviest cuts

Frequently Asked Questions
01
The 15 in one. DN's headline for the two-axis series names 12, 15 and 21 in chucks. The PUMA 4100 B lists 15 in with 2,000 rpm and 2,379 N·m (1,755 ft-lb); the PUMA 4100 C lists 21 in with 1,500 rpm and 3,280 N·m (2,419 ft-lb); the PUMA 4100 LA lists 12 in with 3,000 rpm and 1,584 N·m (1,168 ft-lb).
02
1,042 mm (41 in), on 1,105 mm (44 in) of Z travel. The PUMA 4100 LB is the long-bed version with the same 15 in chuck and spindle rating, and it turns 2,092 mm (82 in). Staying on the short bed and going up to the 21 in chuck costs length: the PUMA 4100 C turns 1,002 mm (39 in) on the same Z travel.
03
Its table lists X and Z travel only, with no live-tool speed and no Y travel, so it turns, bores, threads and drills on the spindle centreline. A bolt circle or a keyway is a second operation on another machine. Where that matters, the PUMA 5100 LYA is listed with a 4,000 rpm live-tool speed and the same 15 in chuck.
04
DN describes the PUMA 4100/5100 series as a machining solution for a wide range of pipes and mentions solutions aimed at threading performance. What the table for the PUMA 4100 B does not give is a spindle through hole, so it cannot tell you what diameter of pipe or bar passes through the 15 in spindle. Ask DN for the bore of this configuration before planning that work.
05
DN lists 4,654 × 2,056 × 2,194 mm (183 × 81 × 86 in) as length, width and height and a machine weight of 9,950 kg (21,936 lb). The PUMA 4100 C on the same travels weighs 10,450 kg (23,038 lb). Check floor loading and lifting capacity against those figures before delivery.
