Overview

The DN Solutions PUMA 4100 LMB is the 15 in, long-bed, live-tool member of the PUMA 4100 family. Its table reads 2,028 mm (80 in) of maximum turning length, 550 mm (22 in) of maximum turning diameter, a 2,000 rpm main spindle at 30 kW (40 hp) and 1,611 N·m (1,188 ft-lb), 12 turret stations and live tools to 4,000 rpm.

Read the spindle line carefully, because it is not the spindle of the two-axis 15 in machines. The PUMA 4100 B lists 35 kW (47 hp) and 2,379 N·m (1,755 ft-lb) at the same 2,000 rpm, about 48% more torque than this model. The 30 kW (40 hp) figure is also lower than its live-tool neighbours: the PUMA 4100 LMA and the PUMA 4100 LMC both list 37 kW (50 hp). A buyer who assumes the 15 in live-tool machine cuts like the two-axis one will be planning with the wrong numbers.

Where the LMB fits is between those neighbours. The PUMA 4100 LMA has a 12 in chuck, 3,000 rpm and 1,024 N·m (755 ft-lb); the PUMA 4100 LMC has a 21 in chuck, 1,500 rpm and 2,432 N·m (1,794 ft-lb). For shafts too heavy for the 12 in chuck of the PUMA 4100 LMA but with sections small enough to want more than the 1,500 rpm of the PUMA 4100 LMC, the 15 in chuck at 2,000 rpm is the compromise.

The live tools turn a long lathe into a one-setup machine for shafts with drilled, tapped or slotted features. Twelve stations have to hold both the turning tools and the rotary ones, so tool planning matters on complex parts. The table lists no Y travel, which keeps milled features on the spindle centreline, and no power figure for the live-tool drive.

Z travel is 2,155 mm (85 in) and X travel 352 mm (14 in), with rapids of 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z. The machine weighs 11,550 kg (25,463 lb) and is listed at 5,774 × 2,275 × 2,272 mm (227 × 90 × 89 in) as length, width and height.

Strengths & Limitations

Strengths

15 in chuck with 4,000 rpm live tools on 2,155 mm (85 in) of Z travel
1,611 N·m (1,188 ft-lb) of spindle torque, above the 1,024 N·m (755 ft-lb) of the PUMA 4100 LMA
2,000 rpm top speed, against 1,500 rpm on the 21 in PUMA 4100 LMC
12 turret stations, two more than the two-axis PUMA 4100 B
2,028 mm (80 in) of turning length at 550 mm (22 in) of turning diameter

Limitations

Spindle power is 30 kW (40 hp), below the 37 kW (50 hp) of the PUMA 4100 LMA and PUMA 4100 LMC
Torque is well under the 2,379 N·m (1,755 ft-lb) of the two-axis PUMA 4100 B with the same chuck size
No Y travel is listed, so off-centre milling is not possible
The table gives a live-tool speed but no live-tool power or torque

Best For

Heavy shafts up to 2,028 mm (80 in) that need drilled, tapped or slotted features Parts that need a 15 in chuck and more than the 1,500 rpm of the PUMA 4100 LMC Medium-duty turning within 1,611 N·m (1,188 ft-lb) combined with on-centre milling Shops that want to finish long parts without a transfer to a mill

Frequently Asked Questions

01 Is the PUMA 4100 LMB spindle the same as on the two-axis 15 in models?

No. The PUMA 4100 LMB lists 30 kW (40 hp) and 1,611 N·m (1,188 ft-lb) at 2,000 rpm. The two-axis PUMA 4100 B, also with a 15 in chuck and 2,000 rpm, lists 35 kW (47 hp) and 2,379 N·m (1,755 ft-lb). Heavy roughing parameters proven on the two-axis machine should be re-checked against the lower figures before they are run here.

02 How does the PUMA 4100 LMB compare with the PUMA 4100 LMA and PUMA 4100 LMC?

All three share 2,155 mm (85 in) of Z travel, 12 stations and 4,000 rpm live tools. The PUMA 4100 LMA has a 12 in chuck, 3,000 rpm, 37 kW (50 hp) and 1,024 N·m (755 ft-lb), and turns 2,060 mm (81 in). The PUMA 4100 LMB has a 15 in chuck, 2,000 rpm, 30 kW (40 hp) and 1,611 N·m (1,188 ft-lb), and turns 2,028 mm (80 in). The PUMA 4100 LMC has a 21 in chuck, 1,500 rpm, 37 kW (50 hp) and 2,432 N·m (1,794 ft-lb), and turns 1,988 mm (78 in).

03 What milling can the live tools do without a Y axis?

With X and Z travel only, a rotary tool stays on the spindle centreline. It can drill and tap on the face or the diameter and mill slots and keyways as wide as the cutter. The live tools run to 4,000 rpm. Features that sit off-centre, or flats that must be milled to a set width, are beyond what this table supports.

04 What does the PUMA 4100 LMB weigh and how large is it?

It weighs 11,550 kg (25,463 lb), and DN lists 5,774 × 2,275 × 2,272 mm (227 × 90 × 89 in) as length, width and height. That is the same listed size as the long-bed PUMA 4100 LA, which weighs 10,900 kg (24,030 lb).
