Overview
The DN Solutions PUMA V400 is a vertical turning center (VTC) — the smallest in DN Solutions' vertical turning lineup — designed for disc-type and flanged parts where gravity-assisted loading and a compact footprint give it a decisive advantage over horizontal lathes. With a 12-inch chuck, 26 kW (35 hp) spindle delivering 863 Nm (637 ft-lb) of torque at up to 3,000 RPM, this machine handles brake rotors, gear blanks, bearing rings, and pump housings with the rigidity and efficiency that high-volume production demands.
The PUMA V400 turns up to 496 mm (19.5 in) in diameter and 461 mm (18 in) in height. Axis travels are 268 mm (11 in) on X and 488 mm (19 in) on Z. Rapid traverse runs 20 m/min on X and 24 m/min on Z. The 12-station turret provides ample tool capacity, and an optional rotary tool spindle at 4,000 RPM enables light milling and drilling operations. The vertical spindle orientation means workpieces load from the top with gravity assistance, simplifying automation and reducing part handling time.
At 6,000 kg (13,228 lb) in a compact 1,475 mm x 2,075 mm footprint, the PUMA V400 packs heavy-duty turning capability into minimal floor space. DN Solutions describes it as their 'smallest high-performance, heavy-duty VTC' — purpose-built for shops with limited floor space that need vertical turning capability. The Fanuc 0i-Plus control handles both turning and optional milling operations. This machine competes with the Mazak VTC-300C, Emag VL 4, and Okuma V80R in the compact vertical turning segment.

Strengths & Limitations
Strengths
- Vertical spindle orientation enables gravity-assisted loading, simplifying automation and reducing part handling time
- 863 Nm (637 ft-lb) of torque is exceptional for a 12-inch chuck machine, handling heavy cuts in cast iron and steel effortlessly
- Compact 1,475 mm x 2,075 mm footprint delivers heavy-duty vertical turning in minimal floor space
- Optional 4,000 RPM rotary tool spindle adds milling and drilling capability for complete part processing
- 12-station turret provides ample tool capacity for complex disc-type parts requiring multiple operations
Limitations
- Vertical orientation limits part length to 461 mm (18 in) — shaft work and long components are not feasible
- 6,000 kg machine weight with vertical height of 3,210 mm requires adequate ceiling clearance and floor preparation
- Chip evacuation requires careful management in vertical orientation to prevent chips from falling back onto the workpiece
- Higher cost than comparable horizontal lathes is justified only when the vertical orientation's advantages are fully leveraged

Frequently Asked Questions
01
New PUMA V400 machines run $140,000-$210,000 depending on options. The V400M variant with live tooling adds $20-40K. The V400P variant includes a parts loader for automated production. Used machines from 2016-2022 sell in the $60,000-$120,000 range.
02
Vertical lathes excel at disc-type and flanged parts for three reasons: gravity assists part loading (especially with automation), chips fall away from the cut zone improving surface finish, and the vertical spindle puts clamping force in line with gravity for more secure workholding. For shaft work or parts with high length-to-diameter ratios, horizontal lathes are better.
03
The V400M variant includes a rotary tool spindle at 4,000 RPM that enables light milling, drilling, and tapping operations. This isn't a replacement for a machining center, but it handles cross-holes, flats, and keyways without requiring a secondary setup on a mill.
04
Both are compact vertical turning centers for disc-type production parts. The Emag VL 4 has a built-in automation concept with integrated pick-up spindle, while the PUMA V400 uses conventional top-loading. The PUMA V400 offers more raw cutting power (35 hp vs Emag's ~28 hp) and a more conventional machine layout that's easier for general-purpose shops to adopt.
