DN Solutions PUMA VTR 2025

The DN Solutions PUMA VTR 2025 is the flagship of the VTR lineup — a massive ram-type vertical turning lathe that swings workpieces up to 2,500 mm (98 in) in diameter. That's over eight feet across. With 2,000 mm (79 in) of turning length, this machine handles the largest production turning work you'll encounter short of custom-built one-off boring mills. We're talking power generation turbine casings, industrial gearbox housings, large marine components, and mining equipment that weighs as much as a pickup truck.

The spindle steps up to 75 kW (101 hp) with an enormous 46,720 Nm (34,459 ft-lb) of torque at 200 RPM. That's nearly forty-seven thousand Newton-meters — enough force to maintain stable cuts on workpieces weighing several tons even during heavy interrupted face cutting. The 200 RPM ceiling is dictated by physics: spinning a 2,500 mm diameter workpiece faster creates centrifugal forces that'd challenge any machine structure.

X-axis travel extends to a massive 2,640 mm (104 in), and Z reaches 1,400 mm (55 in). Rapids are 10 m/min on both axes. The machine itself weighs 55,000 kg (121,254 lb) — that's over 121,000 pounds of cast iron sitting on a 7,296 mm by 4,836 mm footprint and standing 7,600 mm tall. You don't install a VTR 2025; you build a facility around it.

The FANUC control handles the precision turning cycles, and despite the machine's immense size, it's capable of finishing operations that hold tight tolerances across the full 98-inch swing. For heavy industry shops turning the largest cylindrical components in energy, marine, mining, and heavy equipment sectors, the VTR 2025 is the machine that makes it possible.
