DN Solutions PUMA VTR 1620

The DN Solutions PUMA VTR 1620 is where the VTR lineup starts getting into truly large-scale vertical turning territory. With a 2,000 mm (79 in) max turning diameter and 1,800 mm (71 in) turning length, this machine handles workpieces that are over six feet across and five feet tall. If you're machining large turbine casings, massive bearing housings, or industrial gearbox components, this is the class of machine that gets the job done.

The spindle pushes 45 kW (60 hp) with 24,668 Nm (18,194 ft-lb) of torque at 300 RPM. Nearly twenty-five thousand Newton-meters of torque — that's enough to maintain stable cuts on multi-ton castings during heavy facing operations. The lower 300 RPM ceiling reflects the enormous table diameter and the extreme centrifugal forces involved in spinning workpieces this large at higher speeds.

X-axis travel spans a massive 2,220 mm (87 in) — nearly seven and a half feet of cross travel. Z-axis reaches 1,200 mm (47 in). Rapids hold at 12 m/min on X and 10 m/min on Z. The ram-type head rides on heavy-duty box ways, and the entire structure weighs 39,000 kg (85,980 lb). That's almost 86,000 pounds of cast iron providing a rigid cutting platform.

The machine sits on a 6,500 mm by 4,757 mm footprint and stands 6,345 mm tall. You need a proper facility with crane capability, engineered foundations, and overhead clearance to accommodate a machine like this. The FANUC control handles standard turning cycles with the precision required for large-diameter finishing operations where a thousandth of an inch matters across a 79-inch swing.
