Overview
The DN Solutions PUMA 800 LB II is the long-bed, low-speed variant of the 800 series, combining 3,200 mm (126 in) of turning length with a custom-order chuck and a spindle optimized for maximum torque at 500 RPM. At 55 kW (74 hp) with 8,076 Nm (5,957 ft-lb) of torque, it matches the 800 L II's power output but gears it down for applications where every Newton-meter of torque at the chuck face matters.
The 500 RPM limit is a deliberate engineering choice. At large diameters on heavy steel and cast iron, you're often cutting at 150-300 RPM anyway. The lower gear ratio lets the spindle deliver peak torque more effectively at these working speeds. The custom-order chuck means your workholding is specified to match your exact application rather than choosing from standard sizes.
X-axis travel is 470 mm, Z extends to 3,235 mm with 900 mm (35 in) of swing. Rapids run 12 m/min on X and 10 m/min on Z. The 12-station turret handles production tooling needs. Box-way construction is standard across all axes, and the FANUC control provides reliable programming.
At 22,000 kg (48,502 lb), the 800 LB II matches the 800 L II in mass and footprint. The difference is in the spindle configuration — lower max speed, optimized torque delivery, and custom workholding. For shops that have specific applications requiring maximum torque on long, heavy parts and need non-standard chuck configurations, the LB II provides a tailored solution.

Strengths & Limitations
Strengths
- 8,076 Nm torque optimized for low-speed delivery at 500 RPM for maximum cutting force at the chuck
- 3,200 mm turning length handles the longest parts in the 900 mm swing class
- Custom-order chuck means workholding is tailored to your specific application
- 55 kW spindle sustains heavy cutting over extended operations
- 22,000 kg mass and box-way construction provide exceptional stability
- 12-station turret handles complex multi-operation parts
- Same proven 800 series platform with low-speed optimization
Limitations
- 500 RPM max severely limits versatility — designed exclusively for large-diameter heavy work
- Custom-order chuck extends lead times and adds procurement complexity
- 22,000 kg and 7.4 meter length demand engineered foundations
- 10 m/min Z rapids are slow across 3.2 meters of travel
- No live tooling, Y-axis, or sub-spindle
- Very limited used market for this specialized configuration

Frequently Asked Questions
01
Choose the LB II when your application requires a non-standard chuck configuration and you're primarily cutting at speeds below 500 RPM. The lower gear ratio optimizes torque delivery at these working speeds. If a standard 32-inch chuck works for your parts, the 800 L II with its higher 750 RPM ceiling offers more flexibility.
02
New PUMA 800 LB II machines typically run $330,000-$450,000 depending on the custom chuck configuration and options. The custom-order nature may affect pricing and delivery time. Used machines are extremely rare on the open market.
03
The "custom order" designation means DN Solutions will spec the workholding based on your application requirements. This can include non-standard chuck sizes, special jaw configurations, and application-specific clamping setups. Work with your DN Solutions distributor to define the right configuration.
04
Both use custom-order chucks at 500 RPM with identical spindle specs. The key difference is bed length: the LB II provides 3,200 mm turning length versus the B II's 1,600 mm. The LB II is 1.6 meters longer and 5,500 kg heavier. Choose based on the length of your work.
