Overview
The Doosan Puma GT 3100 is the 12 in chuck model in DN Solutions' GT range of turning centers, and its spindle is built around torque: 1,613 N·m (1,190 ft-lb) and 35 kW (47 hp) with a 2,800 rpm maximum. It turns parts up to 481 mm (19 in) in diameter and 755 mm (30 in) long. Doosan Machine Tools became DN Solutions in 2022, and this model remains on the company's list.
A 2,800 rpm ceiling is low for small diameters, where the spindle and not the insert will set the surface speed. At large diameters the picture reverses, and 1,613 N·m is what deep roughing passes in steel and cast iron ask for. The Puma 2600SY shows the opposite choice: a 10 in machine with 599 N·m (442 ft-lb) at up to 4,000 rpm. Anyone turning mostly bar-size work is looking at the wrong lathe here; anyone roughing forgings and castings on a 12 in chuck is looking at the right one.
DN's table gives this model two axes. X travel is 260 mm (10 in) and Z is 830 mm (33 in), with rapids of 24 m/min (945 ipm) and 30 m/min (1,181 ipm), and the turret has 10 stations. There is no row for a Y-axis, driven tools, a sub-spindle, bar capacity or the control, so settle those with DN Solutions before ordering. DN describes the range as covering 8, 10 and 12 in chuck sizes with a box guideway structure, a layout that favours heavy cuts over axis speed.
For installation, the machine is 4,068 mm (160 in) long, 2,102 mm (83 in) wide and 1,915 mm (75 in) high, and it weighs 5,500 kg (12,125 lb).

Strengths & Limitations
Strengths
- 1,613 N·m (1,190 ft-lb) of spindle torque for deep roughing cuts at large diameters
- 35 kW (47 hp) spindle power on a 12 in chuck machine
- Turns up to 481 mm (19 in) in diameter and 755 mm (30 in) in length
- Rapid traverse of 30 m/min (1,181 ipm) in Z and 24 m/min (945 ipm) in X
- Box guideway structure, as DN Solutions describes the GT range
Limitations
- The 2,800 rpm maximum limits surface speed on small diameters
- The turret has 10 stations, against 12 on the Puma 2600SY
- The table lists X and Z only, with no Y-axis, driven-tool or sub-spindle row, so milled features go to another machine
- Bar capacity, spindle bore and the control are not stated in the table

Frequently Asked Questions
01
DN Solutions lists a maximum spindle torque of 1,613 N·m (1,190 ft-lb) and a maximum spindle power of 35 kW (47 hp), with a top speed of 2,800 rpm. The combination favours heavy cuts at large diameters over high surface speed on small ones.
02
The maximum turning diameter is 481 mm (19 in) and the maximum turning length is 755 mm (30 in), on a 12 in chuck. Axis travel is 260 mm (10 in) in X and 830 mm (33 in) in Z.
03
The table for this model lists X and Z travel and a 10-station turret, and has no row for driven tools, a Y-axis or a sub-spindle. If a job needs milled or cross-drilled features, confirm with DN Solutions what the machine can be supplied with before planning around it.
04
The machine measures 4,068 × 2,102 × 1,915 mm (160 × 83 × 75 in) as length, width and height, and weighs 5,500 kg (12,125 lb). Add clearance for the chip conveyor, door opening and maintenance access.
05
The Puma 2600SY is a 10 in machine with a Y-axis, a 12-station turret and 599 N·m (442 ft-lb) at up to 4,000 rpm. The Puma GT 3100 has a 12 in chuck, 1,613 N·m (1,190 ft-lb) at up to 2,800 rpm and a 10-station turret on two axes.
