Vertical Turning Overview

The lathe is one of the oldest machine tools used for straight, radial, and taper turning of machined components. The introduction of computer numerical control (CNC) elevated lathe turning technology to a new level. Today, CNC machines provide extreme accuracy operating at very high speeds in the manufacturing process of precision machined components. Turning processes have evolved to include live tooling (rotating tools) to bring CNC milling type capability to more efficient turning operations.

A vertical CNC turning center or lathe rotates metal parts in a vertical orientation during the machining process. The raw material is held in the chuck by jaws, mandrel, collet, or face driver and connected to the headstock assembly, which drives workpiece rotation with a heavy-duty motor. The turret assembly travels along the Z-axis ways, holding the single-point cutting tools against the workpiece to remove material on each “up and down” pass; this is a multi-axis, subtractive manufacturing method.

Vertical lathes allow for larger diameter, and heavier turned part machining while requiring less floor space compared to horizontal turning centers. Drawbacks to vertical CNC turning machines are part length limitations and overall chip removal. We offer vast selections of surface finish from semi-finished to fine finishing, often not requiring a grinding process.

Vertical Lathe Anatomy

Headstock Assembly (not visible) - Drives the live spindle of the lathe
Chuck - Positioned at the end of the spindle holding the rotating workpiece
Jaws - Clamps the workpiece in the chuck
Ways Z-Axis (not visible) - The rails the index drive and tooling travel parallel to the workpiece upon
Ways X-Axis (not visible) - The rails the index drive and tooling travel perpendicular to the workpiece upon
Workpiece - Clamps into the chuck by jaws
Multi-Tool Turret - Holds multiple cutting tools at the ready
Cutting Tool - Removes material from the workpiece to form a part - subtractive manufacturing
