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 XLC puts a 21 in chuck and 3,280 N·m (2,419 ft-lb) of spindle torque on a long machine with 3,150 mm (124 in) of Z travel. It moves in X and Z only, carries a 10-station turret, and its spindle tops out at 1,500 rpm on 37 kW (50 hp).
Those spindle figures point at large-diameter roughing more than fast finishing. The maximum turning diameter is 550 mm (22 in), barely more than the chuck itself, so the work this machine suits is heavy shafts and rolls that fill the turning diameter. At 1,500 rpm, small diameters on the same part will run below the surface speed carbide wants. That is a normal trade on a lathe of this size, and worth accepting only if most of the metal comes off at the large end.
The short-bed PUMA 4100 C carries the same 21 in chuck, 1,500 rpm, 37 kW (50 hp) and 3,280 N·m (2,419 ft-lb), but turns 1,002 mm (39 in) on 1,105 mm (44 in) of Z. The XLC's maximum turning length is 3,080 mm (121 in). Against the 15 in PUMA 4100 B, with 2,379 N·m (1,755 ft-lb) at 2,000 rpm, the 21 in spindle gives about 38% more torque and gives up a quarter of the top speed.
At 12,900 kg (28,440 lb) it is a heavy installation, and the listed size is 7,024 × 2,276 × 2,335 mm (277 × 90 × 92 in) as length, width and height. Rapids are 16 m/min (630 ipm) in X and 20 m/min (787 ipm) in Z. The table does not state a spindle bore for this model. DN Solutions quotes a Ø375 mm maximum through hole for pipe work across the series, so a buyer with pipe or hollow shafts should ask which bore the XLC is supplied with.

Strengths & Limitations
Strengths
- 3,280 N·m (2,419 ft-lb) of spindle torque, about 38% more than the 2,379 N·m (1,755 ft-lb) of the 15 in PUMA 4100 B
- 21 in chuck on a machine with a 550 mm (22 in) maximum turning diameter
- Maximum turning length of 3,080 mm (121 in) on 3,150 mm (124 in) of Z travel
- 37 kW (50 hp) spindle motor, against 35 kW (47 hp) on the PUMA 4100 B
Limitations
- 1,500 rpm maximum spindle speed limits surface speed on small diameters
- Turning only: the 10-station turret has no live tool speed listed
- 12,900 kg (28,440 lb) and a 7,024 mm (277 in) length call for a prepared foundation and crane access
- Spindle bore is not stated in the table for this model; the Ø375 mm figure on the series page is a family maximum

Frequently Asked Questions
01
Mainly in bed length. The PUMA 4100 C has 1,105 mm (44 in) of Z travel, a 1,002 mm (39 in) maximum turning length and a weight of 10,450 kg (23,038 lb). The XLC has 3,150 mm (124 in) of Z travel, turns 3,080 mm (121 in) and weighs 12,900 kg (28,440 lb). Chuck size, spindle speed, power and torque are the same on both in DN Solutions' table.
02
A 1,500 rpm spindle rated 37 kW (50 hp) and 3,280 N·m (2,419 ft-lb), carrying a 21 in chuck. The table gives a single power figure for it. It does not list the spindle nose or bore, so confirm both if the job involves pipe or hollow shafts.
03
Not as listed. The table shows X and Z travel, a 10-station turret and no live tool speed or Y travel. Other members of the family do list driven tools: the PUMA 5100 LYA and PUMA 5100 LYC each show a 12-station turret with 4,000 rpm live tools.
04
Floor loading and access. The machine weighs 12,900 kg (28,440 lb) and measures 7,024 mm (277 in) in length, 2,276 mm (90 in) in width and 2,335 mm (92 in) in height. A workpiece of up to 3,080 mm (121 in) also needs crane coverage and clear space at the loading side. Tailstock and steady rest details are not in the table and should be settled in the quotation.
