Overview
The DN Solutions PUMA 4100 MC puts 4,000 rpm live tools on the 21 in, short-bed PUMA 4100. It turns 550 mm (22 in) in diameter and 938 mm (37 in) in length, with a main spindle rated 37 kW (50 hp) and 2,432 N·m (1,794 ft-lb) at up to 1,500 rpm and a 12-station turret.
Short, wide and heavy is the shape of part these figures describe. A 21 in chuck almost fills the 550 mm (22 in) turning diameter, and 938 mm (37 in) is the shortest turning length of the short-bed models with live tools: the PUMA 4100 MB turns 978 mm (39 in) and the PUMA 4100 MA 1,010 mm (40 in). Think of large flanges, valve bodies, wheel hubs, bearing housings and thick rings. Almost all of them carry drilled and tapped holes, which is where the live tools come in. Roughing, finishing and hole-making happen in one clamping, and a heavy part is lifted once.
The spindle figures are not those of the two-axis 21 in machine. The PUMA 4100 C lists 3,280 N·m (2,419 ft-lb) at the same 37 kW (50 hp) and 1,500 rpm, about 35% more torque than the 2,432 N·m (1,794 ft-lb) here. On interrupted cuts in forgings and castings at large diameter that gap is felt, so depth of cut should be planned from this model's own figure. The 1,500 rpm limit matters less on this kind of work, since large diameters reach cutting speed at low rpm.
No Y travel appears in the table. Hole patterns on a pitch circle and radial holes are within reach of a centreline tool; milled flats to a set width and off-centre pockets are not. The live-tool drive power is not listed either.
Machine weight is 10,600 kg (23,369 lb). X travel is 352 mm (14 in), Z travel 1,105 mm (44 in), rapids 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z, and the listed size is 4,654 × 2,056 × 2,194 mm (183 × 81 × 86 in) as length, width and height.

Strengths & Limitations
Strengths
- 21 in chuck with 4,000 rpm live tools, for turning and drilling large flanges in one clamping
- 2,432 N·m (1,794 ft-lb) of spindle torque, the highest of the three short-bed live-tool models: the PUMA 4100 MB lists 1,611 N·m (1,188 ft-lb)
- 37 kW (50 hp) spindle rating
- 12 turret stations, against 10 on the two-axis PUMA 4100 C
- 550 mm (22 in) of turning diameter on a machine weighing 10,600 kg (23,369 lb)
Limitations
- Turning length is only 938 mm (37 in)
- Torque is below the 3,280 N·m (2,419 ft-lb) of the two-axis PUMA 4100 C
- 1,500 rpm top speed limits surface speed on small bores and diameters
- No Y travel is listed, so off-centre milling is outside the table

Frequently Asked Questions
01
The PUMA 4100 MC has live tools running to 4,000 rpm and 12 turret stations; the PUMA 4100 C has 10 stations and no live-tool speed in its table. The PUMA 4100 C has the stronger spindle, 3,280 N·m (2,419 ft-lb) against 2,432 N·m (1,794 ft-lb), and turns 1,002 mm (39 in) against 938 mm (37 in). Chuck size, 37 kW (50 hp) and 1,500 rpm are common to both.
02
Parts that are large in diameter and short: up to 550 mm (22 in) across and 938 mm (37 in) long by the table. Flanges, hubs and housings usually need bolt holes, and the 4,000 rpm live tools can drill and tap them on the centreline in the same clamping as the turning. Long shafts are better matched to the PUMA 4100 LMC, which turns 1,988 mm (78 in).
03
For the diameters a 21 in chuck is chosen for, generally yes: surface speed rises with diameter, so large parts reach cutting speed at low spindle speed. It becomes a limit on small bores and small-diameter features. The PUMA 4100 MB runs to 2,000 rpm with a 15 in chuck and the PUMA 4100 MA to 3,000 rpm with a 12 in chuck.
04
It weighs 10,600 kg (23,369 lb). DN lists 4,654 × 2,056 × 2,194 mm (183 × 81 × 86 in) as length, width and height. Allow for the lifting gear needed to load heavy parts into a 21 in chuck, which the listed dimensions do not cover.
05
The table for the PUMA 4100 MC lists no through hole. DN presents the PUMA 4100/5100 series as a solution for a wide range of pipes, with solutions to improve threading performance, but that statement carries no bore figure for this model. If tube or bar has to pass through the spindle, ask DN for the bore of the 21 in configuration before ordering.
