Overview

The DN Solutions PUMA VTR 1620 M adds live tooling to the already massive VTR 1620 platform, creating a vertical turning center that can turn, drill, tap, and mill workpieces up to 2,000 mm (79 in) in diameter. When you're machining a turbine casing that needs both precision turning and drilled bolt patterns, or a large gearbox housing that needs bored seats and tapped mounting holes, the 1620 M does it all without a crane-lift to a second machine.

The spindle delivers 45 kW (60 hp) with 24,668 Nm (18,194 ft-lb) of torque at 300 RPM — identical to the base 1620. The 3,000 RPM live tooling spindle handles drilling, tapping, counterboring, and keyway cutting. For parts in the 79-inch diameter class, the milling capability means you can face a flange, bore a housing, and drill the entire bolt circle in one clamping. The concentricity you get from single-setup machining is impossible to replicate when moving parts this large between machines.

X-axis travel is 2,220 mm (87 in), Z reaches 1,200 mm (47 in), and max turning length extends to 1,800 mm (71 in). Rapids hold at 12 m/min on X and 10 m/min on Z. The FANUC control coordinates turning and milling operations with full interpolation for the live tooling spindle.

At 40,000 kg (88,185 lb), the 1620 M is a full ton heavier than the base model, adding up to nearly 88,200 pounds of machine. The footprint matches at 6,500 mm by 4,757 mm with a 6,345 mm height. This is a capital machine purchase for a serious production facility. For shops that regularly need combined turning and milling on large-diameter parts, the VTR 1620 M represents the pinnacle of DN Solutions' vertical turning capability.

Strengths & Limitations

Strengths

3,000 RPM live tooling enables drilling, tapping, and milling on 79-inch diameter parts in one setup
24,668 Nm torque handles heavy turning on the largest castings and forgings
Single-setup machining of turned and milled features ensures concentricity on critical large components
40,000 kg machine mass provides exceptional rigidity for combined turn-mill operations
2,000 mm turning diameter and 1,800 mm turning length cover the largest production turning work
Eliminates crane transfers between machines for bolt patterns, tapped holes, and keyways on large parts

Limitations

40,000 kg weight demands heavy-duty engineered foundation and high-bay facility infrastructure
3,000 RPM live tooling limits milling speed — not a replacement for a horizontal boring mill on heavy milling
300 RPM table speed severely limits surface finish on features smaller than the max diameter
6.5m x 4.8m footprint plus 6.3m height requires purpose-built facility space
Top-of-range pricing makes this a major capital investment with long payback on light utilization

Best For

Power generation facilities producing turbine casings with turned bores and drilled bolt patterns Heavy equipment manufacturers machining large gearbox housings with bored seats and tapped holes Oil and gas shops turning and drilling massive valve bodies and wellhead components Shipbuilding facilities machining large marine bearing housings and coupling flanges Facilities needing single-setup concentricity on critical large-diameter components Shops upgrading from manual VBMs that need combined turning and milling in one machine

Frequently Asked Questions

01 What's the difference between VTR 1620 and 1620 M?

The M adds a 3,000 RPM live tooling spindle for drilling, tapping, and milling operations. The base 1620 is turning-only. The M weighs 1,000 kg more (40,000 kg vs 39,000 kg) and costs roughly $60-100K more. If your parts need any drilled, tapped, or milled features, the M saves you a trip to a second machine.

02 How much does a VTR 1620 M cost?

New machines typically run $650,000-$880,000 depending on tooling package and options. These are custom-order machines with lead times often exceeding 6 months. Used machines are rare given the specialized nature of this equipment.

03 Can the live tooling handle serious milling work?

The 3,000 RPM live tooling is designed for secondary operations: bolt circle drilling, tapping, counterboring, keyway cutting, and light face milling. For heavy milling stock removal, you'd still need a horizontal boring mill. Think of the live tooling as eliminating secondary setups, not replacing a dedicated milling machine.

04 What foundation does the VTR 1620 M need?

A 40,000 kg machine plus multi-ton workpieces requires an engineered concrete foundation designed by a structural engineer. Typical requirements include reinforced concrete pads of 600-1,000 mm depth with vibration isolation mounts. The machine manufacturer provides foundation drawings during the quoting process.
