Overview

The DN Solutions PUMA 1000 MB is the maximum-torque variant of the PUMA 1000 series, built for the largest and heaviest turning work. If you thought the MA's 11,011 N-m was impressive, the MB pushes to 12,040 N-m (8,880 ft-lb) — enough torque to move mountains, or at least roughing passes on massive forgings and castings.

The trade for that extra torque is spindle speed: 300 RPM max versus the MA's 500 RPM. That makes the MB specifically optimized for the largest diameter work where surface speed at the part OD is adequate even at low RPM. At 800 mm diameter, 300 RPM delivers about 750 SFM — still workable for steel, and more than enough for the initial roughing passes these machines typically perform.

The work envelope is identical to the MA: 1,000 mm (39 in) max turning diameter and 2,040 mm (80 in) max turning length. Axis travels are 540 mm (21 in) on X and 2,130 mm (84 in) on Z with 12/16 m/min rapids. The 75 kW (101 hp) spindle motor is the same, just geared differently for the lower speed and higher torque.

The 12-station turret with 3,000 RPM live tooling carries over from the MA. Custom chuck sizing is standard for both models.

At 23,000 kg (50,706 lb), the MB is 2,000 kg heavier than the MA, reflecting additional gearing and structural reinforcement. The external dimensions remain the same at 6,595 mm (260 in) long. Foundation requirements go up proportionally — if you're already planning for a PUMA 1000, the extra 2 tons shouldn't change your foundation design dramatically, but it needs to be accounted for.

The MB is the right choice when your typical work sits at the upper end of the diameter range and you need maximum cutting force for heavy roughing. For shops that split between smaller and larger work within the 1,000 mm range, the MA's higher speed gives more flexibility.

Strengths & Limitations

Strengths

12,040 N-m (8,880 ft-lb) is maximum torque in the PUMA 1000 series for the heaviest roughing
75 kW (101 hp) spindle with low-speed gearing maximizes cutting force at large diameters
Same 1,000 mm swing and 2,040 mm turning length as the MA for identical work envelopes
Live tooling at 3,000 RPM for milling features on large-diameter parts
Built for the toughest materials — forgings, castings, and large-diameter heavy alloys
FANUC 0i-TF Plus control brings CNC precision to heavy-duty turning

Limitations

300 RPM max speed restricts the machine to large-diameter work only — no mid-size versatility
23,000 kg (50,706 lb) demands heavy foundations and major rigging for installation
Higher price than the MA for work that may not need the extra torque
Slow rapids at 12/16 m/min add non-cutting time, though it's less significant on large parts
Custom chuck lead times can extend project timelines

Best For

Shops exclusively turning the largest diameter parts in the 600-1,000 mm range Oil & gas manufacturers machining heavy drill collars and large-diameter pipe Power generation facilities turning large turbine shafts and generator components Heavy industry applications requiring maximum cutting force on tough forgings Roll grinding and reconditioning operations in steel and aluminum mills

Frequently Asked Questions

01 When should I choose the MB over the MA?

Choose the MB when your typical work is at the larger end of the diameter range (600-1,000 mm) and the material is tough — heavy forgings, large castings, or high-alloy steel. The extra torque lets you take deeper cuts and maintain feeds that would stall the MA. If you need more speed versatility for a range of diameters, the MA is better.

02 Can the MB handle finishing operations at 300 RPM?

For large-diameter work, 300 RPM provides adequate surface speed for finishing. At 800 mm diameter, you're getting about 750 SFM. For smaller diameters where you'd want higher surface speed, the MA at 500 RPM gives better flexibility. Most shops using the MB do roughing on this machine and may finish on a different lathe if needed.

03 Why is the MB heavier than the MA if the envelope is the same?

The extra 2,000 kg comes from the heavier gearing needed to deliver 12,040 N-m of torque and additional structural reinforcement to handle the higher cutting forces. The extra mass also contributes to vibration damping during the heavy roughing passes this machine is designed for.

04 What kind of tooling does the MB use?

The 12-station turret accepts standard heavy-duty turning tools appropriate for the scale of work. Live tooling runs at 3,000 RPM for drilling, tapping, and milling. Tooling selection at this scale is typically application-specific — work with your tooling supplier and DN Solutions dealer to spec the right holders and inserts.
