Overview

The DN Solutions PUMA 4100 LA puts the 12 in chuck and the highest spindle speed of the two-axis PUMA 4100 models on the long bed. It turns 2,124 mm (84 in) in length and 550 mm (22 in) in diameter, with 2,155 mm (85 in) of Z travel, a 3,000 rpm spindle rated 35 kW (47 hp) and 1,584 N·m (1,168 ft-lb), and a 12-station turret.

Speed is the reason to pick the A spindle. The PUMA 4100 LB, on the same bed, has a 15 in chuck and lists 2,000 rpm with 2,379 N·m (1,755 ft-lb) from the same 35 kW (47 hp). Shafts are mostly finished at moderate diameters, where a higher top speed keeps surface speed up and finishing passes short, so for typical shaft work the 3,000 rpm matters more often than the extra torque would. The smaller chuck also leaves the most turning length: 2,124 mm (84 in) here against 2,092 mm (82 in) on the PUMA 4100 LB.

The turret is the other difference worth noticing. This model lists 12 stations, while the PUMA 4100 LB lists 10. A long shaft with several diameters, grooves and threads uses tools quickly, and two more stations can decide whether a job runs without a tool swap.

It remains a turning machine. The table shows X travel of 352 mm (14 in), rapids of 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z, and neither a live-tool speed nor Y travel. Keyways and cross holes go to another machine.

The installation is substantial: 5,774 × 2,275 × 2,272 mm (227 × 90 × 89 in) as length, width and height, and 10,900 kg (24,030 lb). The table does not cover the tailstock or steady rests, which a part near full length will need.

Strengths & Limitations

Strengths

3,000 rpm spindle on a long-bed heavy lathe, against 2,000 rpm on the PUMA 4100 LB
2,124 mm (84 in) of maximum turning length on 2,155 mm (85 in) of Z travel
12 turret stations, two more than the 10 of the PUMA 4100 LB
35 kW (47 hp) and 1,584 N·m (1,168 ft-lb) at the spindle
550 mm (22 in) of turning diameter with a 12 in chuck

Limitations

Torque of 1,584 N·m (1,168 ft-lb) is well below the 2,379 N·m (1,755 ft-lb) of the PUMA 4100 LB
No live-tool speed or Y travel in the table, so milled features need a second machine
Rapid traverse is 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z
5,774 mm (227 in) long and 10,900 kg (24,030 lb), with tailstock and steady rest details not in the table

Best For

Shafts up to 2,124 mm (84 in) long that are finished at moderate diameters Long parts with many diameters, grooves and threads that fill a 12-station turret Work that needs up to 3,000 rpm more than it needs maximum torque Turning-only shaft production with milling done elsewhere

Frequently Asked Questions

01 Why choose the PUMA 4100 LA over the PUMA 4100 LB?

For spindle speed, turret capacity and a little more length. The PUMA 4100 LA lists 3,000 rpm, 12 stations and 2,124 mm (84 in) of turning length. The PUMA 4100 LB lists 2,000 rpm, 10 stations and 2,092 mm (82 in). Power is 35 kW (47 hp) on both. The PUMA 4100 LB answers with a 15 in chuck and 2,379 N·m (1,755 ft-lb) against 1,584 N·m (1,168 ft-lb), so it is the better fit for heavy cuts on large diameters.

02 What is the largest part the PUMA 4100 LA can turn?

550 mm (22 in) in diameter and 2,124 mm (84 in) in length. X travel is 352 mm (14 in) and Z travel is 2,155 mm (85 in). The chuck is 12 in, so a part near the full turning diameter is much larger than the chuck that holds it, and workholding for such parts should be discussed with DN.

03 Is there a longer two-axis PUMA 4100 with the same spindle?

The PUMA 4100 XLA lists the same 12 in chuck, 3,000 rpm, 35 kW (47 hp) and 1,584 N·m (1,168 ft-lb) on 3,180 mm (125 in) of Z travel, and turns 3,152 mm (124 in). It weighs 11,900 kg (26,235 lb) against 10,900 kg (24,030 lb) for the PUMA 4100 LA.

04 Does the PUMA 4100 LA have live tooling?

No live-tool speed appears in its table, and there is no Y travel. The PUMA 4100 LMA is the long-bed 12 in model with live tools: it lists a 4,000 rpm live-tool speed, 2,060 mm (81 in) of turning length and a spindle of 37 kW (50 hp) and 1,024 N·m (755 ft-lb).

05 How much room does the PUMA 4100 LA take?

DN lists 5,774 × 2,275 × 2,272 mm (227 × 90 × 89 in) as length, width and height, and the machine weighs 10,900 kg (24,030 lb). Add space at the ends for loading long stock by crane, which the listed dimensions do not include.
