Overview

The DN Solutions PUMA 700 II is a large-bore heavyweight turning center built for the biggest jobs on the shop floor. With a 24-inch chuck, 55 kW (74 hp) spindle, and a massive 8,076 Nm (5,957 ft-lb) of torque, this machine handles the kind of large steel forgings, castings, and heavy cylindrical components that would overwhelm anything in the standard lathe lineup. The box-way construction provides the foundation rigidity that large-diameter heavy cuts absolutely require.

The PUMA 700 II swings 900 mm (35 in) in diameter and turns up to 1,600 mm (63 in) in length. Axis travels are 470 mm (19 in) on X and 1,650 mm (65 in) on Z. Rapid traverse runs 12 m/min on X and 16 m/min on Z — deliberately slower than mid-size machines because at this scale, positioning accuracy and stability matter far more than speed. The 12-station turret provides ample tool capacity for the complex roughing and finishing sequences these large parts demand. Spindle speed tops out at 1,500 RPM, which is appropriate for the large diameters this machine is designed to swing.

At 16,500 kg (36,376 lb), the PUMA 700 II is a serious piece of iron that requires reinforced foundations, heavy rigging equipment, and careful installation planning. The Fanuc 0i-Plus control keeps programming familiar for operators coming from smaller DN Solutions machines. This machine competes with the Mazak Slant Turn 550 and Okuma LH55-N in the large-bore heavy-duty segment, serving oil & gas, shipbuilding, mining, and power generation customers who need to turn parts measured in feet, not inches.

Strengths & Limitations

Strengths

8,076 Nm (5,957 ft-lb) of spindle torque is immense — handles the heaviest roughing operations in large steel forgings and castings
900 mm (35 in) max turning diameter accommodates the large-bore work that exceeds 21-inch chuck machine capacity
55 kW (74 hp) spindle provides sustained power for long roughing cycles on heavy workpieces
12-station turret offers generous tool capacity for the multi-step roughing and finishing sequences large parts require
16,500 kg of machine mass provides the thermal stability and vibration damping essential for precision on large-diameter parts

Limitations

16,500 kg machine weight demands reinforced foundations, heavy rigging, and significant installation lead time and cost
12 m/min X-axis and 16 m/min Z-axis rapid traverse rates make non-cutting time substantial on complex programs
1,500 RPM spindle speed ceiling limits small-diameter finishing operations — this machine is purpose-built for large diameters
High acquisition cost of $280-420K and floor space requirements limit this to shops with consistent large-part volume

Best For

Oil & gas manufacturers turning large pipe flanges, wellhead components, blowout preventer parts, and drill collars Shipbuilding and marine manufacturers producing propeller shafts, stern tubes, and large cylindrical hull components Power generation shops turning turbine housings, generator rotors, and large bearing seats Mining equipment manufacturers producing large rollers, drums, and heavy wear components

Frequently Asked Questions

01 What does a DN Solutions PUMA 700 II cost?

New PUMA 700 II machines run $280,000-$420,000 depending on options and configuration. The investment is significant but justified for shops with consistent large-diameter work. Used machines from 2015-2022 sell in the $120,000-$250,000 range depending on hours and condition.

02 What kind of foundation does the PUMA 700 II need?

At 16,500 kg, the PUMA 700 II requires a reinforced concrete foundation typically 300-400 mm thick with appropriate rebar and anchor bolt preparation. DN Solutions provides detailed foundation drawings. Many shops need to pour a separate isolation pad to prevent vibration transmission to adjacent machines.

03 How does the PUMA 700 II compare to the PUMA 1000?

The PUMA 1000 is the next step up with a custom-made chuck (typically 30+ inches), 1,000 mm max turning diameter, and 75 kW spindle with over 11,000 Nm of torque. The 700 II handles 24-inch chuck work up to 900 mm diameter. Choose the 700 II for most heavy-duty applications; the 1000 is for truly oversized components.

04 Can the PUMA 700 II be used for general turning work?

Technically yes, but it's wildly inefficient for parts that fit on a 10 or 12-inch chuck lathe. The slow rapids, large footprint, and high operating cost make it impractical for anything but large-diameter work. Run your standard turning work on PUMA 2600 or 5100 machines and reserve the 700 II for parts that genuinely need its capacity.
