Overview
Shaft work is the reason to pick the DN Solutions PUMA DNT 2600 L. It is the long-bed version of DN's two-axis box-guideway lathe, with 1,078 mm (42.4 in) of maximum turning length on 1,100 mm (43.3 in) of Z travel, a 460 mm (18.1 in) turning diameter and a 10 in chuck. A 12 in chuck is an option.
Almost every other row matches the short PUMA DNT 2600: 26 kW, 735 N·m, 3,500 rpm, 260 mm (10.2 in) of X travel and a 10-station turret with 12 stations optional. The PUMA DNT 2600 stops at 658 mm (25.9 in) of turning length. What the added bed takes is room and mass. The PUMA DNT 2600 L is 3,800 mm (149.6 in) long, 1,839 mm (72.4 in) wide and 4,900 kg (10,803 lb), where the PUMA DNT 2600 is 3,355 mm (132.1 in) long, 1,729 mm (68.1 in) wide and 4,300 kg (9,480 lb). Both stand 1,780 mm (70.1 in) high.
A long, slender workpiece changes what limits the cut. On a bar of modest diameter held at one end, deflection and chatter arrive long before 735 N·m is used up, so support matters more than spindle torque. DN lists several tailstock types for the series and says a steady rest is easy to retrofit, but the table carries no tailstock or steady rest figures. Get them before committing a shaft job to this machine.
With no driven tools and no Y travel in the table, keyways, flats and cross-holes go to another machine. The PUMA DNT 2600 LM adds live tools at 6,000 rpm on a 12-station turret, and its envelope shrinks to 380 mm (15 in) in diameter and 1,030 mm (40.5 in) in length. Staying two-axis keeps the larger swing. Next to DN's Y-axis PUMA 2600 LSY II, which lists 599 N·m (442 ft-lb) and weighs 7,850 kg (17,306 lb), this is a far lighter machine with more spindle torque and far less it can finish in one setup.
Rapid traverse is 30 m/min (1,181.1 ipm) in Z, which counts on a stroke this long, and 24 m/min (944.9 ipm) in X.

Strengths & Limitations
Strengths
- 1,078 mm (42.4 in) of turning length, against 658 mm (25.9 in) on the short PUMA DNT 2600
- The 460 mm (18.1 in) turning diameter is kept on the long bed; the live-tool PUMA DNT 2600 LM lists 380 mm (15 in)
- 735 N·m and 26 kW at the spindle, with a 12 in chuck available as an option
- 4,900 kg (10,803 lb), a little under the 4,950 kg (10,913 lb) of the PUMA DNT 2600 LM
- Several tailstock types and a retrofittable steady rest are listed for the PUMA DNT series
Limitations
- No tailstock or steady rest figures in the table, on a machine whose 1,078 mm (42.4 in) turning length depends on them
- No driven tools or Y travel listed; the PUMA DNT 2600 LM is the long-bed version with 6,000 rpm live tools
- The listed turret has 10 stations, with 12 as an option
- Occupies 3,800 × 1,839 mm (149.6 × 72.4 in) of floor, more than the 3,355 × 1,729 mm (132.1 × 68.1 in) of the PUMA DNT 2600
- The 3,500 rpm maximum is low for small-diameter shafts in aluminium or brass

Frequently Asked Questions
01
Bed length. The PUMA DNT 2600 L has 1,100 mm (43.3 in) of Z travel and 1,078 mm (42.4 in) of turning length; the PUMA DNT 2600 has 680 mm (26.8 in) and 658 mm (25.9 in). Turning diameter, spindle, chuck and turret rows are the same. The long machine is 3,800 mm (149.6 in) long and weighs 4,900 kg (10,803 lb), against 3,355 mm (132.1 in) and 4,300 kg (9,480 lb) for the PUMA DNT 2600.
02
DN's series description lists various tailstock types and says steady rest installation is easy to retrofit. It gives no figures for either, and the spec table has no tailstock or steady rest rows. For a shaft approaching 1,078 mm (42.4 in), ask DN which tailstock is fitted and what diameter range the steady rest covers.
03
The PUMA DNT 2600 LM adds live tools at 6,000 rpm and a 12-station turret, so cross-holes and end-face drilling can be done in the same setup. In return its turning diameter is 380 mm (15 in) and its turning length 1,030 mm (40.5 in), where the PUMA DNT 2600 L lists 460 mm (18.1 in) and 1,078 mm (42.4 in). If the parts are turned only, the two-axis machine holds more.
04
DN lists 3,800 × 1,839 × 1,780 mm (149.6 × 72.4 × 70.1 in) as length, width and height, and a machine weight of 4,900 kg (10,803 lb). The table does not include a chip conveyor or bar feeder in those figures, so add their space when planning the layout.
05
The table gives 26 kW, 735 N·m and a 3,500 rpm maximum, with a 10 in chuck and 12 in as an option. DN also lists a high-torque spindle option for the series without saying which rating the table shows. Spindle bore and bar capacity are not stated, so through-spindle bar work needs a question to DN.
