Overview

The DN Solutions PUMA 4100 LMC is the largest-chuck live-tool model on the long PUMA 4100 bed: a 21 in chuck, 1,988 mm (78 in) of maximum turning length, 550 mm (22 in) of maximum turning diameter and a 12-station turret with rotary tools to 4,000 rpm. The main spindle is rated 37 kW (50 hp) and 2,432 N·m (1,794 ft-lb) and tops out at 1,500 rpm.

Machine weight is 12,050 kg (26,566 lb); the two-axis PUMA 4100 C with the same chuck size weighs 10,450 kg (23,038 lb) on the short bed.

Two figures deserve a second look. First, torque. The PUMA 4100 C lists 3,280 N·m (2,419 ft-lb) from the same 37 kW (50 hp) and 1,500 rpm, so the live-tool version gives up about a quarter of the two-axis torque. Its 2,432 N·m (1,794 ft-lb) is still well above the 1,611 N·m (1,188 ft-lb) of the PUMA 4100 LMB, and it is the same torque figure the PUMA 5100 LYA lists at 2,000 rpm. Second, length. The larger the chuck, the less of the Z travel is left for the part: turning length here is 1,988 mm (78 in) from 2,155 mm (85 in) of Z, against 2,028 mm (80 in) on the PUMA 4100 LMB and 2,060 mm (81 in) on the PUMA 4100 LMA.

The kind of part this suits is large in diameter at one end and long: flanged shafts, rolls with big journals, heavy tube with features to drill. The 21 in chuck holds the large end, the spindle roughs it at low speed, and the 4,000 rpm tools then drill and tap a flange face or cut a keyway along the shaft without the part leaving the machine. Features must sit on the centreline, since the table has no Y travel, and it gives no power for the live-tool drive.

X travel is 352 mm (14 in). Rapids are 16 m/min (630 ipm) on X and 20 m/min (787 ipm) on Z. DN lists 5,774 × 2,275 × 2,272 mm (227 × 90 × 89 in) as length, width and height.

Strengths & Limitations

Strengths

21 in chuck combined with 4,000 rpm live tools on a 12-station turret
2,432 N·m (1,794 ft-lb) of spindle torque from 37 kW (50 hp)
1,988 mm (78 in) of turning length, against 1,002 mm (39 in) on the short-bed PUMA 4100 C
Flange drilling and keyway milling in the turning setup, on parts up to 550 mm (22 in) in diameter
12,050 kg (26,566 lb) of machine weight

Limitations

Torque is below the 3,280 N·m (2,419 ft-lb) of the two-axis PUMA 4100 C at the same power and speed
1,500 rpm top speed is slow for the small-diameter sections of a shaft
No Y travel in the table: bolt holes and slots only where a centreline tool can reach
Turning length of 1,988 mm (78 in) uses less of the 2,155 mm (85 in) Z travel than the smaller-chuck models

Best For

Flanged shafts and rolls up to 1,988 mm (78 in) long held in a 21 in chuck Large-diameter roughing at 2,432 N·m (1,794 ft-lb) followed by drilling and tapping Heavy parts where a second setup on a mill means another crane lift Low-speed turning with on-centre milling at up to 4,000 rpm

Frequently Asked Questions

01 How much torque does the PUMA 4100 LMC give up against the two-axis PUMA 4100 C?

The PUMA 4100 LMC lists 2,432 N·m (1,794 ft-lb); the PUMA 4100 C lists 3,280 N·m (2,419 ft-lb). Both are rated 37 kW (50 hp) with a 1,500 rpm top speed and a 21 in chuck. The two-axis figure is about 35% higher, so roughing cuts sized for the PUMA 4100 C need to be reduced on the live-tool machine.

02 What live-tool capability does the PUMA 4100 LMC have?

A 12-station turret with a live-tool speed of 4,000 rpm. The table lists X and Z travel only, so rotary tools work on the spindle centreline: drilling and tapping on a face or a diameter, and slots or keyways the width of the cutter. Live-tool power and torque are not in the table and should be requested for heavy drilling.

03 How does the PUMA 4100 LMC compare with the PUMA 5100 LYA?

The PUMA 5100 LYA lists a 15 in chuck, 2,000 rpm, 37 kW (50 hp) and 2,432 N·m (1,794 ft-lb), turns 2,050 mm (81 in) and weighs 13,000 kg (28,660 lb). The PUMA 4100 LMC has a 21 in chuck, 1,500 rpm, the same power and torque figures, 1,988 mm (78 in) of turning length and 12,050 kg (26,566 lb). Both list 4,000 rpm live tools and 550 mm (22 in) of turning diameter.

04 What part sizes does the PUMA 4100 LMC cover?

Up to 550 mm (22 in) in turning diameter and 1,988 mm (78 in) in turning length, with 352 mm (14 in) of X travel and 2,155 mm (85 in) of Z travel. The 21 in chuck is what shortens the turning length. On the short bed the PUMA 4100 C, with the same chuck size, turns 1,002 mm (39 in) on 1,105 mm (44 in) of Z travel.

05 What should be confirmed before ordering?

Three things the table does not state: the spindle through hole, which decides whether tube or bar can pass through the headstock, the power of the live-tool drive, and tailstock or steady rest support for long parts. Also check the floor for 12,050 kg (26,566 lb) and a listed size of 5,774 × 2,275 × 2,272 mm (227 × 90 × 89 in) as length, width and height.
