Overview
The DN Solutions PUMA 800 II is a heavy-duty 2-axis horizontal turning center featuring a 32-inch chuck, 900 mm (35 in) max turning diameter, and 1,600 mm (63 in) of turning length. With a 55 kW (74 hp) spindle delivering 8,076 Nm (5,957 ft-lb) of torque at up to 750 RPM, it's designed for turning the largest and heaviest workpieces that fit within a horizontal lathe envelope.
A 32-inch chuck is a statement of capability. You don't spec a chuck that size unless your work demands it — large pipe flanges, heavy pressure vessel components, mining equipment housings, and industrial castings that need serious clamping force. The 750 RPM spindle speed provides adequate surface speed for most ferrous materials at these diameters. You're not chasing RPM on a machine like this — you're leveraging torque.
X-axis travel is 470 mm, Z is 1,650 mm, and rapids run 12 m/min on X and 16 m/min on Z. The 12-station turret provides tool capacity for multi-operation parts. Box-way construction across all axes is the only way to build a machine at this scale with the rigidity these applications demand.
The PUMA 800 II weighs 16,500 kg (36,376 lb) and stretches 5.8 meters long with a 3.2-meter width. It needs an engineered foundation, proper electrical infrastructure, and a heavy-duty chip management system. The FANUC control handles programming duties reliably. For manufacturers in oil and gas, power generation, mining, and heavy industrial sectors, the 800 II provides the combination of swing, chuck size, and torque that defines this class of machine.

Strengths & Limitations
Strengths
- 32-inch chuck provides massive workholding capacity for the largest diameter parts
- 8,076 Nm of torque handles the most aggressive roughing in heavy ferrous materials
- 900 mm swing covers the full range of large-diameter turning work
- 55 kW spindle sustains heavy cutting without power fade
- 12-station turret provides tool variety for complex multi-operation parts
- Box-way construction and 16,500 kg mass deliver rock-solid stability
- 750 RPM max speed provides reasonable surface speed for large-diameter steel and cast iron
Limitations
- 750 RPM max speed limits the machine to large-diameter work — impractical for small parts
- 32-inch chuck requires significant hydraulic clamping force and limits spindle acceleration
- 16,500 kg demands engineered foundations and professional installation
- Slow rapids add non-cutting time on tool changes and positioning moves
- No live tooling or Y-axis — strictly 2-axis turning
- Significant capital investment in the $290K-$400K range

Frequently Asked Questions
01
New PUMA 800 II machines typically run $290,000-$400,000 depending on options. The 32-inch chuck and heavy-duty frame command premium pricing. Used machines in good condition sell in the $125,000-$240,000 range.
02
The 800 II uses a standard 32-inch chuck at 750 RPM, while the 800 B II uses a custom-order chuck at 500 RPM. Both deliver identical torque (8,076 Nm) and power (55 kW). The 800 II is the standard choice for most large-diameter applications.
03
Yes. The 8,076 Nm of torque and 55 kW of power handle stainless steel, duplex stainless, and other tough materials. The low-speed, high-torque design is well-suited for materials that generate high cutting forces.
04
For longer turning lengths, the PUMA 800 L II provides 3,200 mm (126 in) of turning length with the same 32-inch chuck and spindle specs. The PUMA 800 LB II offers the same length with a custom-order chuck at 500 RPM.
