Overview
A 12 in chuck on a frame that turns 550 mm (22 in): the DN Solutions PUMA 4100 MA is the short-bed, live-tool PUMA 4100 with the highest main spindle speed of the three chuck sizes, 3,000 rpm. Maximum turning length is 1,010 mm (40 in) on 1,105 mm (44 in) of Z travel, the turret has 12 stations and the live tools run to 4,000 rpm.
The spindle is rated 37 kW (50 hp) and 1,024 N·m (755 ft-lb). For a machine of 9,600 kg (21,164 lb) that is a modest torque figure, and it tells you what the A spindle is for. The two-axis PUMA 4100 B lists 2,379 N·m (1,755 ft-lb) at 2,000 rpm, and even the two-axis PUMA 4100 LA with the same 12 in chuck lists 1,584 N·m (1,168 ft-lb). The MA is the choice when parts are mid-sized and the cycle benefits from speed, while the large frame is kept in reserve for the occasional big diameter that a smaller lathe cannot swing.
X travel of 352 mm (14 in) is what gives the turret room. With live tools mounted, radial drills and end mills stand well out from the turret face, and generous X travel lets them clear the part. The table lists no Y travel, so those tools cut on the centreline: holes on a bolt circle, cross holes through the axis, slots and keyways as wide as the cutter. The table states the live-tool speed but not the drive power.
Rapids are 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z, moderate figures that suit longer cycle parts better than short ones. The machine is listed at 4,654 × 2,056 × 2,194 mm (183 × 81 × 86 in) as length, width and height. If the parts are long, the PUMA 4100 LMA carries the same spindle and live-tool figures on 2,155 mm (85 in) of Z and turns 2,060 mm (81 in).

Strengths & Limitations
Strengths
- 3,000 rpm main spindle with 37 kW (50 hp) on a frame that turns 550 mm (22 in)
- Live tools to 4,000 rpm on a 12-station turret
- 352 mm (14 in) of X travel, which gives live tools room to clear the part
- 1,010 mm (40 in) of turning length on a machine listed at 4,654 mm (183 in) long
- At 9,600 kg (21,164 lb), lighter than the two-axis PUMA 4100 B at 9,950 kg (21,936 lb)
Limitations
- Main spindle torque of 1,024 N·m (755 ft-lb) is less than half the 2,379 N·m (1,755 ft-lb) of the PUMA 4100 B
- No Y travel in the table, so milling stays on the spindle centreline
- A 12 in chuck on a 550 mm (22 in) turning diameter limits how large-diameter parts can be gripped
- Rapids of 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z are slow for short-cycle work

Frequently Asked Questions
01
The table does not give a reason, only the figures. The PUMA 4100 MA lists 37 kW (50 hp) and 1,024 N·m (755 ft-lb) at 3,000 rpm. The two-axis PUMA 4100 LA, with the same 12 in chuck and top speed, lists 35 kW (47 hp) and 1,584 N·m (1,168 ft-lb). Treat the live-tool model as a different spindle and size cuts from its own torque figure.
02
On the same short bed with live tools, the PUMA 4100 MB has a 15 in chuck, 2,000 rpm and 1,611 N·m (1,188 ft-lb), and the PUMA 4100 MC has a 21 in chuck, 1,500 rpm and 2,432 N·m (1,794 ft-lb). Each step up in chuck size lowers top speed and raises torque. The PUMA 4100 MA is the fastest of the three at 3,000 rpm.
03
No Y travel is listed. The table gives 352 mm (14 in) of X travel and 1,105 mm (44 in) of Z travel. On this machine the 4,000 rpm live tools work on the spindle centreline, which covers bolt-circle holes, cross holes through the axis and slots as wide as the cutter. Flats milled to a set width and off-centre holes are not within reach.
04
Maximum turning length is 1,010 mm (40 in) and maximum turning diameter is 550 mm (22 in). For longer work the PUMA 4100 LMA has 2,155 mm (85 in) of Z travel and turns 2,060 mm (81 in), with the same 12 in chuck, 3,000 rpm spindle and 4,000 rpm live tools, at 11,050 kg (24,361 lb).
05
Machine weight is 9,600 kg (21,164 lb) and the listed size is 4,654 × 2,056 × 2,194 mm (183 × 81 × 86 in) as length, width and height. Those dimensions match the two-axis PUMA 4100 B, so the live-tool turret does not change the space the machine is listed to need.
