Overview

The DN Solutions PUMA 4100 LC is a long-bed two-axis lathe built around a 21 in chuck: 2,052 mm (81 in) of maximum turning length, 550 mm (22 in) of maximum turning diameter, and a spindle rated 37 kW (50 hp) and 3,280 N·m (2,419 ft-lb) with a 1,500 rpm top speed. At 11,900 kg (26,235 lb) it outweighs the PUMA 4100 LA on the same bed, which is listed at 10,900 kg (24,030 lb).

This is the configuration for work that is both long and heavy. A 21 in chuck holds large-diameter stock, thick-walled tube and forged shafts with big flanges or journals, and 3,280 N·m (2,419 ft-lb) lets the machine take a deep cut on those diameters at low speed. The same spindle figures on the short bed belong to the PUMA 4100 C, which turns 1,002 mm (39 in) on 1,105 mm (44 in) of Z travel; the LC has 2,155 mm (85 in) of Z.

DN's description of the series puts weight on pipe machining and mentions solutions aimed at threading performance. A long bed and a large chuck are the natural base for that work, but the table for this model lists no spindle through hole, which is the figure that decides what pipe or tube can be fed through the headstock. Get the bore of the LC, and the pipe options available for it, confirmed in writing.

The limits follow from the same choices. 1,500 rpm is slow for small diameters, so a shaft with a slim end section finishes at a low surface speed. The turret has 10 stations, against 12 on the PUMA 4100 LA. There is no live-tool speed and no Y travel in the table. Rapids are 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z, with 352 mm (14 in) of X travel.

DN lists 5,774 × 2,275 × 2,272 mm (227 × 90 × 89 in) as length, width and height.

Strengths & Limitations

Strengths

3,280 N·m (2,419 ft-lb) of spindle torque available along 2,155 mm (85 in) of Z travel
21 in chuck with 550 mm (22 in) of turning diameter
2,052 mm (81 in) of turning length, against 1,002 mm (39 in) on the short-bed PUMA 4100 C
37 kW (50 hp) spindle rating, above the 35 kW (47 hp) of the PUMA 4100 LA

Limitations

1,500 rpm top speed, half the 3,000 rpm of the PUMA 4100 LA
10 turret stations for long parts that can need many tools
The table lists no spindle through hole, the figure pipe and tube work depends on
No live tools or Y travel in the table
11,900 kg (26,235 lb) and 5,774 mm (227 in) of length to accommodate

Best For

Heavy shafts, rolls and tube up to 2,052 mm (81 in) long and 550 mm (22 in) in diameter Deep roughing cuts on large diameters at 3,280 N·m (2,419 ft-lb) Long forgings with large flanges or journals held in a 21 in chuck Low-speed, high-torque turning where 1,500 rpm is sufficient

Frequently Asked Questions

01 How does the PUMA 4100 LC compare with the PUMA 4100 LA?

They share the bed, with 2,155 mm (85 in) of Z travel and 550 mm (22 in) of turning diameter, and sit at opposite ends of the spindle range. The PUMA 4100 LC has a 21 in chuck, 1,500 rpm, 37 kW (50 hp), 3,280 N·m (2,419 ft-lb) and 10 turret stations. The PUMA 4100 LA has a 12 in chuck, 3,000 rpm, 35 kW (47 hp), 1,584 N·m (1,168 ft-lb) and 12 stations. The PUMA 4100 LA turns 2,124 mm (84 in), the PUMA 4100 LC 2,052 mm (81 in).

02 What does the long bed add over the PUMA 4100 C?

Z travel and turning length. The PUMA 4100 C has 1,105 mm (44 in) of Z travel and turns 1,002 mm (39 in). The PUMA 4100 LC has 2,155 mm (85 in) of Z travel and turns 2,052 mm (81 in). Chuck size, spindle speed, power and torque are the same, and weight rises from 10,450 kg (23,038 lb) for the PUMA 4100 C to 11,900 kg (26,235 lb).

03 Can the PUMA 4100 LC machine pipe?

DN presents pipe machining as a use for the series and mentions solutions to improve threading performance. The table for the PUMA 4100 LC does not list a spindle through hole, so whether a given pipe passes through this spindle is a question for DN. Without that figure, plan only on what the table gives: 550 mm (22 in) of turning diameter and 2,052 mm (81 in) of turning length.

04 What are the travels and rapid rates?

X travel is 352 mm (14 in) and Z travel is 2,155 mm (85 in). Rapid traverse is 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z. Neither Y travel nor a live-tool speed is listed, so the two axes are all the machine has to work with.
