Overview

The DN Solutions PUMA V 400 P is the pendulum (twin-spindle) variant of the PUMA V 400 vertical turning platform. The 'P' designation means this machine has two work spindles that alternate between the cutting zone and the load/unload position — while one spindle is cutting, the operator or robot loads the next part on the idle spindle. When the cycle finishes, the spindles swap positions and cutting begins immediately on the fresh part.

Each spindle features a 12-inch chuck running at 3,000 RPM with 26 kW (35 hp) of power and 863 Nm (637 ft-lbs) of torque. Max turning diameter is 496 mm (19.5 in) with 461 mm (18.1 in) turning height — matching the base V 400. The X-axis rapid traverse is slightly faster at 24 m/min compared to the base model's 20 m/min. Z-axis stays at 24 m/min.

The 12-station turret is shared between both spindles, so tooling serves both work positions. At 1,475 mm x 2,075 mm, the footprint matches the standard V 400 — you're getting a twin-spindle production machine in the same space as a single-spindle VTC. Weight holds at 6,000 kg (13,228 lb).

The V 400 P's pendulum design virtually eliminates load/unload time from the production cycle. On parts with 30-60 second cycle times, the loading and unloading overhead on a single-spindle machine can eat 20-30% of total throughput. The pendulum design reclaims all of that time. For high-volume production of disc parts — brake rotors, pulleys, flanges, bearing races — the V 400 P delivers throughput that typically requires two standard machines.

Strengths & Limitations

Strengths

Pendulum twin-spindle design virtually eliminates load/unload time from the production cycle, dramatically increasing throughput
Same compact 1,475 mm x 2,075 mm footprint as the single-spindle V 400 — twin-spindle production in single-spindle floor space
Each spindle delivers full 26 kW / 863 Nm cutting performance — no compromise vs the standard V 400
Ideal for automation with gantry or robot loading on the idle spindle while cutting continues uninterrupted
496 mm max turning diameter matches the base V 400 — no work envelope reduction for the pendulum feature
On short-cycle parts, effectively doubles output compared to a single-spindle VTC

Limitations

Higher acquisition cost of $175K-$260K vs $130K-$195K for the base V 400 — needs volume to justify the premium
Shared turret between both spindles means identical tooling for both work positions — can't run different parts simultaneously
No live tooling or C-axis — parts needing milled features should look at the V 400 M instead
Pendulum mechanism adds maintenance complexity compared to the simpler single-spindle V 400
Best ROI is on short-cycle, high-volume parts — long cycle times reduce the benefit of the pendulum design

Best For

High-volume automotive production of brake rotors, drums, flywheels, and pulleys where throughput drives profitability Bearing manufacturers producing races, cups, and cones in large quantities with short individual cycle times Pump manufacturers turning impellers, wear rings, and seal housings in production volumes Any high-volume disc part application where load/unload time represents a significant percentage of total cycle time Automated production cells where robots load one spindle while the other is cutting for true continuous production

Frequently Asked Questions

01 How does the pendulum design work on the V 400 P?

Two work spindles rotate between a cutting position and a load/unload position. While one spindle is turning a part, the operator or robot unloads the finished part and loads a blank on the idle spindle. When cutting finishes, the spindles swap positions instantly and the next cycle begins. Loading time is completely overlapped with cutting time.

02 How much does a DN Solutions PUMA V 400 P cost?

New PUMA V 400 P machines typically price between $175,000 and $260,000 depending on configuration and automation level. The pendulum design adds roughly $45-65K over the base V 400. Gantry loaders and full automation packages can push above $260K but typically pay for themselves quickly in high-volume applications.

03 What cycle time improvement does the pendulum design provide?

The improvement depends on your current load/unload time relative to cutting time. On parts with 30-second cutting cycles and 15-second load/unload times, the pendulum eliminates that 15 seconds per part — effectively a 33% throughput increase. On parts with longer cutting cycles (2+ minutes), the percentage gain is smaller but still meaningful over a full shift.

04 Can I run different parts on the two spindles?

No. Both spindles share the same turret and tooling, so they must run the same part and program. The pendulum design is for high-volume production of identical parts, not flexible job shop work. If you need to run different parts, a standard single-spindle V 400 is more appropriate.
