Overview

The DN Solutions PUMA GT 3100 L is a two-axis, long-bed lathe for a 12 in chuck, and its headline figure is torque: 1,613 N·m (1,190 ft-lb) from a 35 kW (47 hp) spindle that tops out at 2,800 rpm. It turns up to 481 mm (19 in) in diameter and 1,275 mm (50 in) in length, with a 10-station turret and no live tooling in the table.

Inside the PUMA GT 3100 family this is the heavy-turning column. The PUMA GT 3100 LM shares the 1,350 mm (53 in) Z travel and adds 5,000 rpm live tools on 12 stations, but its spindle is listed at 26 kW (35 hp) and 1,123 N·m (828 ft-lb), and its turning diameter drops to 376 mm (15 in). Against the PUMA GT 3100 LM, the PUMA GT 3100 L has about 44% more torque and about 35% more power.

What that torque buys depends on diameter. At 481 mm (19 in) a roughing cut in steel asks for a great deal of torque at low spindle speed, and that is the work this machine is specified for: large shafts, rolls, forgings and thick-walled tube. DN describes a box guideway structure for the series, which fits the same kind of cutting. The 2,800 rpm ceiling is the other side of the bargain. Small diameters will not reach the surface speeds carbide wants in non-ferrous metals.

Ten stations is a working limit on long parts that need roughing, finishing, grooving, threading and boring tools for more than one diameter range, so write the tool list before assuming one setup. X travel is 260 mm (10 in), and rapids are 24 m/min (945 ipm) on X and 30 m/min (1,181 ipm) on Z.

The machine is 4,633 mm (182 in) long, 2,394 mm (94 in) wide and 2,110 mm (83 in) high, and weighs 6,900 kg (15,212 lb). The table lists no tailstock, steady rest, bar capacity or spindle bore figures, all of which matter on a 1,275 mm (50 in) part.

Strengths & Limitations

Strengths

1,613 N·m (1,190 ft-lb) of spindle torque, about 44% more than the 1,123 N·m (828 ft-lb) of the PUMA GT 3100 LM
35 kW (47 hp) spindle on a box guideway structure
481 mm (19 in) maximum turning diameter with 1,275 mm (50 in) of turning length
1,350 mm (53 in) of Z travel covered at a 30 m/min (1,181 ipm) rapid
12 in chuck as the listed size

Limitations

No live-tool speed, Y travel or sub-spindle in the table; the PUMA GT 3100 LM is the version with 5,000 rpm live tools
The 2,800 rpm maximum spindle speed limits surface speed on small diameters
10-station turret, against 12 stations on the PUMA GT 3100 LM
Occupies 4,633 × 2,394 mm (182 × 94 in) of floor and weighs 6,900 kg (15,212 lb), before any chip conveyor or bar equipment

Best For

Heavy roughing of steel shafts and forgings up to 481 mm (19 in) in diameter Long turned parts up to 1,275 mm (50 in) Two-axis work where torque matters more than spindle speed Large-diameter threading, grooving and boring at low rpm

Frequently Asked Questions

01 How much torque does the PUMA GT 3100 L spindle produce?

DN lists 1,613 N·m (1,190 ft-lb) and 35 kW (47 hp), with a maximum speed of 2,800 rpm. The table gives no speed at which the torque applies and does not describe the drive, so ask for the torque and power curves if the job depends on torque at a particular rpm.

02 What is the difference between the PUMA GT 3100 L and the PUMA GT 3100 LM?

The PUMA GT 3100 L is the two-axis machine: 10 stations, 481 mm (19 in) turning diameter, 1,275 mm (50 in) turning length, 35 kW (47 hp) and 1,613 N·m (1,190 ft-lb). The PUMA GT 3100 LM has 12 stations with 5,000 rpm live tools, turns 376 mm (15 in) by 1,245 mm (49 in), and lists 26 kW (35 hp) and 1,123 N·m (828 ft-lb). Both have 1,350 mm (53 in) of Z travel and a 12 in chuck.

03 Can the PUMA GT 3100 L drill cross-holes or mill flats?

Not as listed. Its table has no live-tool speed and no Y travel, only X and Z with a 10-station turret, so it is a turning, boring, grooving and threading machine. Parts that need driven tools point to the PUMA GT 3100 LM, which lists rotary tools at 5,000 rpm on the same Z travel.

04 How large a part fits in the PUMA GT 3100 L?

Maximum turning diameter is 481 mm (19 in) and maximum turning length is 1,275 mm (50 in), on 260 mm (10 in) of X travel and 1,350 mm (53 in) of Z travel. The chuck is 12 in. Weight limits between centres and through-spindle bar size are not in the table.

05 What floor space and weight does the PUMA GT 3100 L need?

The listed dimensions are 4,633 × 2,394 × 2,110 mm (182 × 94 × 83 in) for length, width and height, and the machine weighs 6,900 kg (15,212 lb). Check the floor loading and the route into the building against those figures, and add space for chip handling and for loading long parts with a crane.
