Vertical Turning Lathe (VTL Machine)
Stallion SV Series — Powerful · Precise · Production-Ready
A Vertical Turning Lathe (VTL) rotates the workpiece around a vertical axis with the tooling positioned above — ideal for large-diameter, disc-shaped, or high-mass components where gravity assists workpiece clamping. The Stallion SV Series is built on a heavy resin-sand cast bed and column treated with stress-relief aging, with a 4-front / 2-rear precision-bearing spindle and pre-tensioned C-grade ground ball screws. Thirteen models across four configurations: single-column standard, heavy-duty, double-column and dual moving-column.

Frequently Asked Questions
What is a Vertical Turning Lathe (VTL)?
A Vertical Turning Lathe (VTL) is a CNC turning machine that rotates the workpiece around a vertical axis with the cutting tools positioned above. The vertical orientation lets gravity assist workpiece clamping, making it ideal for large-diameter, heavy,
When should I use a VTL instead of a horizontal CNC lathe?
Choose a VTL when (1) the workpiece is heavy or large-diameter (clamping is easier and safer vertically), (2) the part is disc-shaped (gravity assists fixturing), (3) you need to machine flanges, brake drums, or hubs that don't lend themselves to horizont
What is the difference between single-column, heavy-duty, double-column and dual-column VTL configurations?
Single-column standard suits general-purpose work. Single-column heavy-duty adds widened guide rail spans and full hard rail for high-tonnage cutting. Double-column distributes cutting forces across two columns for superior thermal stability and accuracy
What components are typically machined on a VTL?
Brake drums, brake discs, automotive wheels and hubs, transmission gears, pulleys, flanges, large bearing rings, and any large-diameter or disc-shaped component requiring turning, facing, or grooving operations. The SV Series is well suited to automotive,
Why is the Stallion SV Series superior to competitor VTLs?
The SV Series is built on a heavy resin-sand cast bed and column treated with stress-relief aging, with a 4-front / 2-rear precision-bearing spindle and pre-tensioned C-grade ground ball screws (Ø40–Ø50) — delivering long-term dimensional stability across
