Overview

The DN Solutions PUMA GT 3100 M puts a 12 in chuck, a 1,123 N·m (828 ft-lb) spindle and 5,000 rpm live tools on a short bed: 830 mm (33 in) of Z travel and 725 mm (29 in) of maximum turning length. Turning diameter is 376 mm (15 in), the turret has 12 stations, and the whole machine weighs 5,650 kg (12,456 lb).

Torque is the reason to pick a 12 in machine for parts this short. The spindle is listed at 26 kW (35 hp) with a 2,800 rpm top speed, and its torque is well above the smaller models nearby in DN's range: the PUMA 2100 LSY II, with the same 830 mm (33 in) of Z travel, lists 358 N·m (264 ft-lb) and 5,000 rpm on an 8 in chuck.

Two relatives are worth checking before deciding. The PUMA GT 3100 LM is this machine with 1,350 mm (53 in) of Z and 1,245 mm (49 in) of turning length, at 7,050 kg (15,543 lb). The PUMA 3100 keeps the 830 mm (33 in) of Z and the same spindle ratings but is a two-axis lathe with a 10-station turret, no live-tool row and a 525 mm (21 in) turning diameter. So the live turret is paid for in diameter, and the long bed in mass.

Without a Y-axis row in the table, the 5,000 rpm tools are for drilling, tapping and centreline slots, not for pockets or offset flats. X travel is 260 mm (10 in). Rapids are 24 m/min (945 ipm) on X and 30 m/min (1,181 ipm) on Z.

On the floor the machine is 3,865 mm (152 in) long and 2,102 mm (83 in) wide, and it stands 1,915 mm (75 in) high. DN's series description mentions a box guideway structure, a user-friendly operation panel and a simple maintenance function, without figures.

Strengths & Limitations

Strengths

1,123 N·m (828 ft-lb) of spindle torque on a machine with only 830 mm (33 in) of Z travel
12-station turret with live tools to 5,000 rpm
12 in chuck with a 376 mm (15 in) maximum turning diameter
Lighter than the long-bed version: 5,650 kg (12,456 lb) against 7,050 kg (15,543 lb) for the PUMA GT 3100 LM
Rapids of 24 m/min (945 ipm) on X and 30 m/min (1,181 ipm) on Z

Limitations

Turning length is 725 mm (29 in); the PUMA GT 3100 LM reaches 1,245 mm (49 in)
No Y travel listed, so the live tools cut on centre only
The main spindle is limited to 2,800 rpm
The two-axis PUMA 3100 turns 525 mm (21 in) in diameter, where this machine turns 376 mm (15 in)

Best For

Short, heavy steel parts up to 376 mm (15 in) in diameter that also need drilled or tapped holes Chucked work within 725 mm (29 in) of turning length Hubs, couplings and flanges finished with 5,000 rpm rotary tools Shops that want 12 in torque without the mass of a long bed

Frequently Asked Questions

01 How does the PUMA GT 3100 M compare with the PUMA GT 3100 LM?

They share the 12 in chuck, the 26 kW (35 hp), 1,123 N·m (828 ft-lb) spindle, the 12-station turret and 5,000 rpm live tools. The PUMA GT 3100 M has 830 mm (33 in) of Z travel and turns 725 mm (29 in); the PUMA GT 3100 LM has 1,350 mm (53 in) of Z and turns 1,245 mm (49 in). The PUMA GT 3100 LM weighs 7,050 kg (15,543 lb) against 5,650 kg (12,456 lb).

02 What is the difference between the PUMA GT 3100 M and the PUMA 3100?

Both list a 12 in chuck, 830 mm (33 in) of Z travel and a 26 kW (35 hp), 1,123 N·m (828 ft-lb), 2,800 rpm spindle. The PUMA 3100 is two-axis with a 10-station turret and turns 525 mm (21 in) in diameter and 790 mm (31 in) in length. The PUMA GT 3100 M has 12 stations with 5,000 rpm live tools and turns 376 mm (15 in) by 725 mm (29 in).

03 What size of part suits the PUMA GT 3100 M?

Parts up to 376 mm (15 in) in diameter and 725 mm (29 in) long, held in a 12 in chuck. With 1,123 N·m (828 ft-lb) available and a 2,800 rpm limit, it favours steel and cast iron at medium and large diameters over small, fast work. Bar capacity is not in the table.

04 Can the PUMA GT 3100 M mill off-centre features?

The table lists X and Z travel only, 260 mm (10 in) and 830 mm (33 in), with live tools at 5,000 rpm. Off-centre milling needs a Y-axis, which this model's table does not show. Features on the centreline, such as cross-holes, face holes and through-slots, are within the listed axes.

05 How big and how heavy is the PUMA GT 3100 M?

Length, width and height are 3,865 × 2,102 × 1,915 mm (152 × 83 × 75 in) and the machine weighs 5,650 kg (12,456 lb). Those figures are for the machine itself, so allow extra room for chip handling and operator access.
