Overview

Long shafts that also need cross-holes, keyways or flats are the case for the DN Solutions PUMA GT 3100 LM. It combines 1,350 mm (53 in) of Z travel and a 12 in chuck with a 12-station turret whose live tools run to 5,000 rpm. Maximum turning length is 1,245 mm (49 in) and maximum turning diameter is 376 mm (15 in).

The main spindle is listed at 26 kW (35 hp) and 1,123 N·m (828 ft-lb) with a 2,800 rpm top speed. That is a low-speed, high-torque spindle, sized for steel at larger diameters, and it leaves the 5,000 rpm rotary tools as the faster spindle on the machine for small drills and end mills.

Putting driven tools on the turret changes the envelope. The two-axis PUMA GT 3100 L, on the same Z travel, turns 481 mm (19 in) in diameter and 1,275 mm (50 in) in length, and is listed with a stronger spindle of 35 kW (47 hp) and 1,613 N·m (1,190 ft-lb). A part near the top of the PUMA GT 3100 L diameter range will not fit here. Going the other way, the PUMA GT 3100 M is the same live-tool machine on a shorter bed, with 830 mm (33 in) of Z, 725 mm (29 in) of turning length and a weight of 5,650 kg (12,456 lb) against 7,050 kg (15,543 lb) for this model.

No Y travel appears in the table. With 260 mm (10 in) of X and tools working on centre, the machine drills and taps radially and axially and mills slots through the centreline. An off-centre hole pattern or a flat held to an exact width calls for one of DN's Y-axis lathes, such as the PUMA 2600 LSY II with 105 mm (4 in) of Y travel on a 10 in chuck.

Rapids are 24 m/min (945 ipm) on X and 30 m/min (1,181 ipm) on Z. The machine measures 4,465 × 2,394 × 2,110 mm (176 × 94 × 83 in) as length, width and height.

Strengths & Limitations

Strengths

5,000 rpm live tools on a 12-station turret, on a bed with 1,350 mm (53 in) of Z travel
1,123 N·m (828 ft-lb) of main spindle torque from 26 kW (35 hp)
1,245 mm (49 in) of maximum turning length with a 12 in chuck
12 turret stations, against 10 on the two-axis PUMA GT 3100 L
Box guideway structure, as DN describes the series

Limitations

Turning diameter is 376 mm (15 in); the two-axis PUMA GT 3100 L turns 481 mm (19 in)
No Y travel in the table, so milled features are limited to the spindle centreline
The main spindle stops at 2,800 rpm, which limits surface speed on small diameters
At 7,050 kg (15,543 lb) it asks more of the floor than the PUMA GT 3100 M at 5,650 kg (12,456 lb)

Best For

Shafts up to 1,245 mm (49 in) that need cross-drilling, tapping or keyways in the same setup Steel parts up to 376 mm (15 in) in diameter that want 1,123 N·m (828 ft-lb) at low speed Shops replacing a lathe-then-mill route on long turned parts Radial and axial drilling with rotary tools up to 5,000 rpm

Frequently Asked Questions

01 What does the PUMA GT 3100 LM add over the PUMA GT 3100 L?

Live tooling and two turret stations. The PUMA GT 3100 LM has a 12-station turret with rotary tools to 5,000 rpm; the PUMA GT 3100 L has 10 stations and no live-tool speed in its table. In exchange the PUMA GT 3100 L turns a larger part, 481 mm (19 in) by 1,275 mm (50 in) against 376 mm (15 in) by 1,245 mm (49 in), and lists 35 kW (47 hp) and 1,613 N·m (1,190 ft-lb) at the spindle against 26 kW (35 hp) and 1,123 N·m (828 ft-lb).

02 Is there a Y-axis on the PUMA GT 3100 LM?

The table lists X travel of 260 mm (10 in) and Z travel of 1,350 mm (53 in) and no Y travel. The live tools therefore cut on the spindle centreline. For Y-axis work DN's range includes the PUMA 2600 LSY II, which lists 105 mm (4 in) of Y travel, a 10 in chuck and 1,350 mm (53 in) of Z.

03 How long a part can the PUMA GT 3100 LM turn?

Up to 1,245 mm (49 in), with a maximum turning diameter of 376 mm (15 in). The PUMA GT 3100 M, the shorter version, turns 725 mm (29 in). Tailstock and steady rest data are not in the table, so ask DN how a part near full length would be supported.

04 How fast are the main spindle and the live tools?

The main spindle runs to 2,800 rpm with 26 kW (35 hp) and 1,123 N·m (828 ft-lb). The live tools run to 5,000 rpm. The table gives no power or torque for the live-tool drive, so the size of end mill or drill it can push is something to confirm before quoting milled features.

05 What space and weight should a shop plan for?

DN lists 4,465 × 2,394 × 2,110 mm (176 × 94 × 83 in) as length, width and height, and 7,050 kg (15,543 lb) of machine weight. Add clearance at the chuck end for loading long stock and space for chip handling, which the listed dimensions do not include.
