Overview
The DN Solutions PUMA VTR 2025 M is the ultimate machine in DN Solutions' vertical turning lineup — a 2,500 mm (98 in) capacity vertical turning center with 3,000 RPM live tooling for combined turn-mill operations on the largest production parts imaginable. When you need to face-turn a massive turbine casing, bore the seating surfaces, and then drill the full bolt circle without unclamping, this is the machine that does it.
The spindle delivers 75 kW (101 hp) with a staggering 46,720 Nm (34,459 ft-lb) of torque at 200 RPM. The 3,000 RPM live tooling adds drilling, tapping, counterboring, and milling capability to the turning operations. On a part this large, the concentricity advantage of single-setup machining isn't just nice to have — it's critical. Moving a multi-ton workpiece between a VTL and a boring mill introduces alignment errors that are extremely difficult to correct.
Max turning length is 2,000 mm (79 in). X-axis spans 2,640 mm (104 in) and Z reaches 1,400 mm (55 in). Rapids are 10 m/min on both axes. The FANUC control coordinates turning and milling cycles with full interpolation, managing the transition between rotational cutting and fixed-spindle milling operations.
At 56,000 kg (123,459 lb), the 2025 M is the heaviest machine DN Solutions makes in the VTR series. The 7,296 mm by 4,836 mm footprint and 7,744 mm height mean this machine needs a purpose-built facility. It's a 1,000 kg heavier and slightly taller than the base 2025 due to the live tooling mechanism. For the world's most demanding large-part turning applications — power generation, marine, heavy equipment, and oil and gas — the VTR 2025 M represents the top of what a single machine can accomplish.

Strengths & Limitations
Strengths
- Combined turn-mill capability on 98-inch diameter parts eliminates the need to crane-transfer multi-ton workpieces to a second machine
- 46,720 Nm torque provides absolute stability on the heaviest interrupted cuts
- 75 kW spindle sustains full-power roughing passes on large castings and forgings
- 3,000 RPM live tooling handles bolt circle drilling, tapping, and keyway cutting on the VTL
- 56,000 kg machine mass is the most rigid platform in the DN Solutions VTR lineup
- Single-setup concentricity on large-diameter features is nearly impossible to achieve any other way
Limitations
- 56,000 kg weight and 7.7m height require purpose-built facility with heavy-duty foundations and crane
- 3,000 RPM live tooling limits milling speed — heavy milling still requires a horizontal boring mill
- 200 RPM table speed severely restricts surface speed on smaller-diameter internal features
- Highest acquisition cost in the entire VTR lineup — a million-dollar-class investment
- Long lead times of 6-12 months for a custom-built machine of this size

Frequently Asked Questions
01
New VTR 2025 M machines typically run $900,000-$1,250,000 depending on tooling configuration and options. Add $50-100K for installation including foundation engineering, rigging, and commissioning. These are built-to-order with 6-12 month lead times.
02
The M adds a 3,000 RPM live tooling spindle for drilling, tapping, and milling. The base 2025 is turning-only. The M weighs 1,000 kg more (56,000 vs 55,000 kg), stands slightly taller (7,744 mm vs 7,600 mm), and costs roughly $100-150K more. If your parts need any drilled or tapped features, the M saves crane transfers to a boring mill.
03
The 3,000 RPM live tooling is designed for bolt circle drilling, tapping, counterboring, spot facing, and keyway cutting — secondary features on parts that are primarily turned. It won't replace a horizontal boring mill for heavy milling work, but it handles the drilling and tapping operations that'd otherwise require moving a multi-ton part to a second machine.
04
Table load capacity varies by configuration — contact DN Solutions for your specific requirements. The 56,000 kg machine mass and heavy-duty table bearings are designed for extremely heavy workpieces. The vertical orientation is advantageous because workpiece weight loads the table bearings axially, which is their strongest orientation.
05
The VTR 2025 M excels at turning, facing, and boring large-diameter parts, with limited milling as a secondary capability. A horizontal boring mill excels at milling and boring but can't turn. For parts that are primarily turned with secondary drilled/tapped features, the VTR 2025 M is the right choice. For parts that need heavy milling, a boring mill is still needed.
