capstan lathe: meaning, definition, pronunciation and examples

A centre lathe (or engine lathe) is general-purpose, where tools are changed manually and mounted on a separate tool post. A capstan lathe has a rotating turret (capstan) that holds multiple tools in sequence, allowing faster production of duplicate parts without tool changes.

Their use has declined significantly with the advent of CNC (Computer Numerical Control) lathes, which offer greater precision, flexibility, and automation. However, they may still be found in some maintenance shops, training schools, or for very specific, simple high-volume tasks where the cost of CNC programming isn't justified.

Often, but purists distinguish them. A 'capstan lathe' typically refers to a lighter, often manually operated machine where the turret moves on a slide or ram. A 'turret lathe' is generally heavier, may have power feed, and the turret is mounted directly on the saddle. In casual use, 'turret lathe' is the broader term.

Operation requires manual dexterity, understanding of cutting speeds/feeds, tool geometry, and the ability to plan an efficient sequence of operations (the 'setup'). Skill is needed to index the turret accurately and produce consistent, in-tolerance parts at a high rate.

A type of lathe used for repetitive production of identical parts, featuring a rotating cylindrical tool holder (capstan) that allows quick change between different cutting operations.

Capstan lathe is usually technical/industrial in register.
