Vertical lathes (VTLs) are characterized by a vertical spindle and horizontal worktable, excelling in machining heavy, large-diameter, short-length workpieces with stability, easy clamping, efficient chip removal, and space-saving design. Below are their core features and details:

Core Structural Features

  • Vertical Spindle Orientation: Spindle is perpendicular to the horizontal plane, with the workpiece clamped on a horizontal rotary table. Workpiece weight acts vertically on the machine base, reducing spindle bending and enhancing rigidity.

  • Horizontal Worktable: Provides a stable platform for heavy workpieces, simplifying loading, positioning, and alignment, often with large diameter capacity (from under 1m to over 20m).

  • Rigid Machine Base: Typically made of high-grade cast iron or mineral casting for vibration damping, ensuring stable cutting under heavy loads.

  • Dual/Twin Ram Design: Optional dual rams enable simultaneous machining of multiple features, boosting productivity.

  • Enclosed Protection & Chip Removal: Fully enclosed design with gravity-assisted chip removal; chips and cutting fluid fall into chutes, preventing re-cutting and aiding heat dissipation.


Key Functional Advantages

  1. Superior Load-Bearing & Stability: Ideal for heavy, disc/ring/box-shaped workpieces. Workpiece weight is supported by the table base, minimizing spindle deflection and ensuring consistent precision.

  2. Efficient Workpiece Handling: Horizontal table allows easy crane loading, reducing labor and alignment time; lower clamping pressure suits fragile parts.

  3. High Precision & Repeatability: Rigid structure and advanced spindle systems (e.g., hydrostatic bearings) deliver tight tolerances, suitable for thin-walled components.

  4. Automation Compatibility: Equipped with automatic tool changers (ATC), pallet changers, and integrated conveyors for unattended operation and short cycle times.

  5. Space Efficiency: Compact footprint (up to 50% smaller than horizontal lathes), optimizing workshop layout and reducing floor space costs.

  6. Multi-Process Capability: With CNC controls and optional milling/grinding heads, performs turning, boring, threading, and milling in one setup.
