Overview
Three metres of turning length is what sets the DN Solutions PUMA 3100 ULY apart. It lists 3,125 mm (123 in) of maximum turning length and 3,190 mm (126 in) of Z travel on a 12 in chuck, with 130 mm (5 in) of Y travel and live tools to 5,000 rpm, so a long shaft can be turned and milled without leaving the machine.
Diameter capacity does not grow with the bed. Maximum turning diameter is 420 mm (17 in), the same figure as the PUMA 3100 LY, which turns 1,285 mm (51 in). The work this machine suits is therefore slender: rolls, screws, hydraulic rods and drive shafts whose length is many times their diameter. Parts of that shape need support along their length. The table says nothing about the tailstock or steady rests, and for a 3,125 mm (123 in) part those are the first things to settle with DN.
The spindle is listed at 26 kW (35 hp), 1,123 N·m (828 ft-lb) and 2,800 rpm. On a long, flexible workpiece the cut is usually limited by chatter before it is limited by the motor, so the torque matters most for roughing near the chuck and on the larger-diameter sections.
Z rapid traverse is 26 m/min (1,024 ipm), lower than the 30 m/min (1,181 ipm) on X. Moves that send the turret back to a safe position add up on a part this long, and keeping the tool-change position close to the cut is worth the programming effort.
Plan the building around it. DN gives 6,585 × 2,280 × 2,315 mm (259 × 90 × 91 in) as length, width and height and 12,300 kg (27,117 lb) of machine weight, against 8,000 kg (17,637 lb) for the PUMA 3100 LY. Loading a three-metre bar also takes crane access and clear floor that the listed dimensions do not include.

Strengths & Limitations
Strengths
- 3,125 mm (123 in) of maximum turning length, against 1,285 mm (51 in) on the PUMA 3100 LY
- 130 mm (5 in) of Y travel and 5,000 rpm live tools available along 3,190 mm (126 in) of Z
- 1,123 N·m (828 ft-lb) of spindle torque from 26 kW (35 hp)
- 12-station turret, so the turning and rotary tools for a long part can stay mounted together
Limitations
- Maximum turning diameter stays at 420 mm (17 in) despite the bed length
- Z rapid traverse is 26 m/min (1,024 ipm), below the 30 m/min (1,181 ipm) on X
- At 6,585 mm (259 in) long and 12,300 kg (27,117 lb), foundation, crane access and floor space need planning
- Tailstock and steady rest data are not in the table, although parts near full length depend on them
- Spindle speed stops at 2,800 rpm

Frequently Asked Questions
01
Maximum turning length is 3,125 mm (123 in) with 3,190 mm (126 in) of Z travel. Maximum turning diameter is 420 mm (17 in) on a 12 in chuck. The table does not describe the tailstock or any steady rest, so how a part near full length is supported has to be agreed with DN.
02
The three share the 12 in chuck, 420 mm (17 in) turning diameter, 130 mm (5 in) of Y travel, the 26 kW (35 hp) spindle and 5,000 rpm live tools. They differ in bed length. The PUMA 3100 LY turns 1,285 mm (51 in) and weighs 8,000 kg (17,637 lb), the PUMA 3100 XLY turns 2,125 mm (84 in) at 10,800 kg (23,810 lb), and the PUMA 3100 ULY turns 3,125 mm (123 in) at 12,300 kg (27,117 lb).
03
No sub-spindle is listed. The table for this model has one spindle speed, 2,800 rpm, plus the 5,000 rpm live-tool speed, so parts are machined from one end with Y-axis milling available along the length. The PUMA 3100 SY, which lists a 4,000 rpm sub-spindle, is a short-bed machine with 765 mm (30 in) of turning length.
04
30 m/min (1,181 ipm) on X and 26 m/min (1,024 ipm) on Z. The shorter PUMA 3100 LY lists 30 m/min (1,181 ipm) as a single figure. On 3,190 mm (126 in) of Z travel, non-cutting moves are a visible part of the cycle, so it pays to keep tool-change positions near the area being cut.
05
The PUMA 4100 XLA turns 3,152 mm (124 in) in length and 550 mm (22 in) in diameter with 1,584 N·m (1,168 ft-lb) at the spindle, but its table lists no Y travel and no live-tool speed. The PUMA 3100 ULY is the choice when the long part also needs milling: it offers 130 mm (5 in) of Y travel and 5,000 rpm live tools, on a smaller 420 mm (17 in) turning diameter.
