Overview
The DN Solutions PUMA 4100 XLB is a two-axis horizontal turning center for long shaft work: 3,150 mm (124 in) of Z travel, a maximum turning length of 3,120 mm (123 in) and a 15 in chuck in front of a 2,000 rpm spindle. Maximum turning diameter is 550 mm (22 in), and X travel is 352 mm (14 in).
The headstock figures are those of the short-bed PUMA 4100 B: 35 kW (47 hp), 2,379 N·m (1,755 ft-lb) and 2,000 rpm on both machines. What changes is the bed. The PUMA 4100 B turns 1,042 mm (41 in) on 1,105 mm (44 in) of Z travel and weighs 9,950 kg (21,936 lb), while the XLB turns about three times that length and weighs 12,400 kg (27,337 lb). A shop that already runs the shorter machine gets the same spindle rating at the chuck and gains the reach to turn a long shaft without re-chucking it.
The turret has 10 stations and the table lists no live tool speed, so this is a turning machine: milled flats, keyways and cross holes go to another operation. Rapid traverse is 16 m/min (630 ipm) in X and 20 m/min (787 ipm) in Z. On a bed this long the Z figure matters more than usual, because every tool change made at the far end of a shaft is followed by a long return move.
Installation needs planning. The machine is 7,024 mm (277 in) long, 2,276 mm (90 in) wide and 2,335 mm (92 in) high. DN Solutions' table for this model gives no spindle bore, tailstock or steady rest figures. DN Solutions presents the PUMA 4100 and PUMA 5100 series as a platform for pipe machining and threading, but the size of pipe that passes through this spindle is not stated. Anyone buying the XLB for slender shafts or for pipe should have those details confirmed in the quotation.

Strengths & Limitations
Strengths
- 3,150 mm (124 in) of Z travel and a 3,120 mm (123 in) maximum turning length, enough to turn long shafts in one chucking
- 2,379 N·m (1,755 ft-lb) of spindle torque from 35 kW (47 hp), the same headstock rating as the short-bed PUMA 4100 B
- 15 in chuck with a 550 mm (22 in) maximum turning diameter
- Z rapid of 20 m/min (787 ipm) shortens the return moves a long bed makes unavoidable
Limitations
- 10-station turret with no live tool speed in the table, so milled features need a second operation
- Spindle speed tops out at 2,000 rpm; the PUMA 4100 LA reaches 3,000 rpm with a 12 in chuck, which suits small-diameter finishing better
- No spindle bore, tailstock or steady rest figures in DN Solutions' table for this model, so pipe capacity and shaft support have to be settled in the quotation
- Needs 7,024 × 2,276 mm (277 × 90 in) of floor and a foundation for 12,400 kg (27,337 lb)

Frequently Asked Questions
01
DN Solutions lists a maximum turning length of 3,120 mm (123 in) on 3,150 mm (124 in) of Z travel, with a maximum turning diameter of 550 mm (22 in). For comparison, the PUMA 4100 LA turns 2,124 mm (84 in) on 2,155 mm (85 in) of Z travel, and the short-bed PUMA 4100 B turns 1,042 mm (41 in).
02
Bed length. Both have a 15 in chuck, a 2,000 rpm spindle rated 35 kW (47 hp) and 2,379 N·m (1,755 ft-lb), and a 10-station turret. The PUMA 4100 B has 1,105 mm (44 in) of Z travel and a 1,042 mm (41 in) turning length at 9,950 kg (21,936 lb). The XLB has 3,150 mm (124 in) of Z, turns 3,120 mm (123 in) and weighs 12,400 kg (27,337 lb).
03
The table for this model lists a 10-station turret and no live tool speed, so plan it as a turning-only machine. Elsewhere in the family, the PUMA 5100 LYA lists a 12-station turret with 4,000 rpm live tools on 2,100 mm (83 in) of Z travel.
04
The machine measures 7,024 mm (277 in) long by 2,276 mm (90 in) wide, stands 2,335 mm (92 in) high and weighs 12,400 kg (27,337 lb). Allow room beyond that for loading long shafts with a crane. DN Solutions' table gives the machine's own dimensions only.
