Overview

The DN Solutions PUMA 800 B II is a heavy-duty 2-axis horizontal turning center built for the biggest, most demanding workpieces in the 900 mm (35 in) swing class. It pairs a custom-order chuck configuration with 1,600 mm (63 in) of turning length and 55 kW (74 hp) pushing 8,076 Nm (5,957 ft-lb) of torque. The "B" designation indicates a low-speed, high-torque spindle variant running at up to 500 RPM — pure muscle for the heaviest cuts.

At 500 RPM max, this isn't a versatile all-rounder. It's a specialist machine for turning large-diameter castings, heavy forgings, and oversized components where surface speed isn't the limiting factor — material removal rate is. The 8,076 Nm of torque means you can take the depth of cut and feed rate you actually want, not what a weaker machine forces you to compromise on.

X-axis travel is 470 mm, Z is 1,650 mm, and rapids hit 12 m/min on X and 16 m/min on Z. The 12-station turret provides tool capacity for complex parts. Box-way construction is standard on all axes — at this scale, there's no alternative.

The PUMA 800 B II weighs 16,500 kg (36,376 lb), putting it firmly in engineered-foundation territory. The 5.8-meter overall length is more manageable than the longer 700 series machines, making it a good fit for shops that need maximum power on shorter, heavier parts. The FANUC control handles programming with industry-standard reliability. For heavy industry manufacturers producing large valve bodies, pump housings, heavy flanges, and industrial castings, the 800 B II has the raw power to match the work.

Strengths & Limitations

Strengths

8,076 Nm of torque handles the most demanding heavy roughing in any ferrous material
900 mm swing accommodates large-diameter castings, forgings, and industrial components
55 kW spindle provides sustained power for extended heavy cutting operations
12-station turret provides more tool capacity than most heavy-duty lathes
16,500 kg mass and box-way construction deliver exceptional stability
More compact footprint than the 700 L II while maintaining the same power and swing
FANUC control with proven reliability

Limitations

500 RPM max speed limits the machine to large-diameter work only — small parts are impractical
Custom-order chuck adds lead time and complexity to the purchase process
16,500 kg requires engineered foundations and professional rigging
1,600 mm turning length is shorter than the L and LB variants for long-part shops
No live tooling or Y-axis capability
Slow rapids (12/16 m/min) add non-cutting time

Best For

Heavy industrial manufacturers turning large castings, forgings, and valve bodies Pump and compressor manufacturers machining large housings and heavy components Oil and gas shops producing heavy flanges, couplings, and short-to-medium tubular parts Power generation manufacturers turning large turbine components and generator parts Shops needing maximum torque on short-to-medium length large-diameter parts

Frequently Asked Questions

01 What's the difference between the PUMA 800 B II and the PUMA 800 II?

The 800 B II runs at 500 RPM max with a custom-order chuck, while the 800 II uses a standard 32-inch chuck at 750 RPM. Both deliver 8,076 Nm of torque and 55 kW of power. The B II is for applications that need even more clamping flexibility at the lowest speeds.

02 What does a PUMA 800 B II cost?

New PUMA 800 B II machines typically run $280,000-$380,000 depending on chuck configuration and options. The custom-order chuck may affect lead time. Used machines are uncommon but sell in the $120,000-$230,000 range.

03 Why only 500 RPM?

At 900 mm turning diameter, 500 RPM gives you approximately 1,414 m/min surface speed — well above typical cutting speeds for steel and cast iron at large diameters. The gear ratio optimization for 500 RPM max allows maximum torque delivery at the chuck.

04 What chuck options are available?

The 800 B II uses a custom-order chuck configuration, meaning the specific chuck size and type are specified based on your application requirements. Contact your DN Solutions distributor to discuss workholding options for your specific parts.
