You Ji VTH Series (Vertical Turning Lathes with Hydrostatic Bearing) up to 8 Meters

The You Ji VTH Series vertical turning lathes are engineered for heavy-duty, high-precision turning of large, heavy, and difficult-to-machine workpieces, commonly found in the aerospace, energy, transportation, and heavy equipment industries. A standout feature of this series is its hydrostatic table bearings, which offer exceptional advantages in precision, load capacity, and machine longevity. Models in bothsingle ram and twin ram configurations are available. Customized sizes and configurations are available upon request.

Like all large-format You Ji CNC machines, the VTH series is constructed with box way guideways for superior rigidity and stability, a Meehanite cast iron base for optimal vibration dampening during cutting, and a ram-type spindle head for enhanced support and stability when handling large tooling. The high-torque spindle drive delivers powerful performance at low RPMs, ideal for demanding cutting operations. For increased flexibility, the machines are available with optional C-axis and live tooling, enabling milling, drilling, and tapping in a single setup. Automatic tool changers, in turret or magazine configurations, further enhance productivity and automation potential.

The hydrostatic table bearings allow the worktable to float on a thin film of oil, eliminating metal-to-metal contact. This design ensures ultra-smooth, vibration-free rotation—critical for precision machining of heavy parts—while significantly reducing wear, maintenance requirements, and downtime related costs.

You Ji’s VTH Series is the ideal solution for extra-large components such as jet engine casings, landing gear parts, wind turbine hubs, valve bodies, large gearboxes, brake discs, bearings, housings, and flange — delivering consistent performance in even the most demanding industrial environments.
