Overview
The DN Solutions Puma VTR1216 is a large ram-type vertical turning center designed for machining the kind of oversized, difficult-to-cut workpieces that won't fit on anything smaller. With a 1,600 mm (63 in) max turning diameter and 1,200 mm (47 in) max turning length, this machine handles large castings, forgings, and fabricated components for energy, mining, shipbuilding, and heavy equipment industries.
The ram-type design uses a vertically-mounted cutting head (ram) that moves on the crossrail, giving the VTR1216 a massive 1,700 mm (67 in) X-axis travel. The spindle delivers 45 kW (60 hp) with an enormous 20,557 Nm (15,162 ft-lb) of torque at a max speed of 400 RPM. Those numbers tell you exactly what this machine is built for — slow, powerful face-turning and boring on massive parts where you're removing serious material.
At 29,500 kg (65,036 lb), the VTR1216 is a serious piece of iron. The massive casting absorbs vibration from heavy interrupted cuts on rough castings and weldments. The table-type design means the workpiece sits on a rotating table, gravity holds it down, and the ram carries the tool to the work. This eliminates the headstock deflection problems you'd fight on a horizontal lathe trying to swing a 1,600 mm diameter part. The Fanuc control handles the straightforward 2-axis programming these large parts typically require.

Strengths & Limitations
Strengths
- 20,557 Nm (15,162 ft-lb) of spindle torque handles the heaviest cuts on large castings and forgings without hesitation
- 1,600 mm (63 in) turning diameter and 1,200 mm turning length accommodate large workpieces that most VTLs can't handle
- Ram-type design with 1,700 mm X-axis travel enables full-face machining of large-diameter parts in a single setup
- 29,500 kg machine weight provides exceptional stability and vibration damping for heavy interrupted cuts
- Vertical table design uses gravity for workholding assistance, simplifying fixturing on large, heavy parts
Limitations
- 400 RPM max spindle speed is very low — this machine is exclusively for large-diameter, low-speed turning work
- 29,500 kg weight and 5.6-meter height require substantial foundation preparation and high-bay facility space
- Slow rapid traverse rates (12/10 m/min) add significant non-cutting time on long-travel moves
- High price point ($450K-$650K) limits this machine to shops with consistent large-part volume to justify the investment

Frequently Asked Questions
01
New VTR1216 machines run $450,000-$650,000 depending on configuration. The M-suffix variant with live tooling adds to the cost. These are capital equipment purchases typically financed over 5-7 years. Used machines are rare on the open market due to specialized applications.
02
The VTR1620 increases max turning diameter to 2,000 mm and turning length to 1,800 mm, with a proportionally larger table and heavier casting. It's the next step up when 1,600 mm turning diameter isn't enough. The VTR2025 goes even larger at 2,500 mm.
03
A ram-type VTL (like the VTR1216) mounts the cutting tool on a ram that moves along a crossrail. This gives much larger X-axis travel for full-face machining of large diameters. Standard VTCs (like the V8300) use a conventional turret on a saddle. Ram-type machines handle the largest work; standard VTCs are more compact and faster.
04
The base VTR1216 is a turning-only machine. The VTR1216M and VTR1216FM variants add live tooling capability for milling, drilling, and tapping. The F suffix indicates a full-function model with additional features. Check with your dealer for specific configuration options.
