Overview
The DN Solutions Puma VT900 is a vertical turning center designed for chucking short, heavy workpieces that would be awkward to load on a horizontal lathe. Gravity does the fixturing work — drop the part into the chuck, close it, and cut. No tailstock drama, no fighting with heavy blanks hanging off a horizontal spindle. The inverted vertical spindle design means chips fall away from the workpiece and cutting zone, keeping finishes clean and reducing recutting.
The VT900 sits between the compact V400 series and the larger VT1100 in DN Solutions' vertical turning lineup. With a 24-inch chuck and a max turning diameter around 900 mm, it handles mid-to-large castings, forgings, and ring-shaped parts common in automotive, heavy equipment, and energy applications. The spindle delivers 45 kW (60 hp) with substantial torque at low RPM — exactly what you need for face-turning large flanges and boring deep bores in cast iron and steel.
The 12-station turret indexes quickly for multi-tool operations, and the rigid box-way construction on both axes soaks up the vibration from heavy interrupted cuts on rough castings. The Fanuc control with iHMI touchscreen keeps programming straightforward. For shops running large-diameter chucking work in moderate volumes, the VT900 eliminates the crane-and-chuck struggle of loading heavy parts on horizontal lathes.

Strengths & Limitations
Strengths
- Vertical spindle orientation uses gravity for part loading — heavy castings and forgings drop into the chuck without crane gymnastics
- Chips fall away from the cutting zone naturally, reducing recutting and improving surface finish on face-turning operations
- 45 kW (60 hp) spindle with massive low-end torque handles heavy interrupted cuts on rough castings and forgings without stalling
- Box-way construction on both axes provides vibration damping for aggressive roughing on large-diameter parts
- 12-station turret supports complex multi-tool operations without manual tool changes
Limitations
- Large footprint and 16,000 kg machine weight require substantial floor space and foundation preparation
- 1,200 RPM max spindle speed limits small-diameter finishing work — this machine is built for big, heavy parts
- Higher price point than equivalent horizontal lathes due to specialized vertical construction
- Limited availability in the used market compared to horizontal Puma models

Frequently Asked Questions
01
New Puma VT900 machines typically run $250,000-$350,000 depending on options like milling capability, chip conveyor configuration, and automation integration. The VT series commands a premium over horizontal lathes due to the specialized vertical construction.
02
The VT1100 steps up to a 32-inch chuck with 1,100 mm max turning diameter and 65 kW (87 hp) spindle power versus the VT900's 24-inch chuck and 900 mm capacity. The VT1100 weighs 22,000 kg compared to the VT900's 16,000 kg. Choose the VT900 for mid-size vertical turning work; the VT1100 for the largest castings and forgings.
03
Vertical turning centers excel at short, heavy, large-diameter parts. Gravity assists part loading (drop it in the chuck), chips fall away from the cut naturally, and the vertical spindle orientation handles the weight of heavy workpieces without deflection issues. Horizontal lathes are better for long shaft work.
04
The base VT900 is a 2-axis turning-only machine. DN Solutions offers M-suffix variants (like the VT1100M) with live tooling and C-axis capability for milling, drilling, and tapping. Check with your dealer for VT900M availability.
