Difference Between Turret Lathes and Capstan Lathes
















- Turret and Capstan, both, are production machines and are usually of semiautomatic, type. Both turret and capstan lathes are provide with tool head, usually hexagon, to carry a set of tools and to supplement this by an additional slide carrying tools for cutting off and forming operations.
A Capstan lathe is usually a small or medium size machine with the tool head carried upon a slide mounted in a saddle bolted to the bed of the lathe, while a turret lathe has the (hexagon) tool head mounted on a saddle sliding directly on the bed.

Metal lathe or metalworking lathe are generic terms for any of a large class of lathes designed for precisely machining relatively hard materials. They were originally designed to machine metals; however, with the advent of plastics and other materials, and with their inherent versatility, they are used in a wide range of applications, and a broad range of materials. In machining jargon, where the larger context is already understood, they are usually simply called lathes, or else referred to by more-specific subtype names (toolroom lathe, turret lathe, etc.). These rigid machine tools remove material from a rotating workpiece via the (typically linear) movements of various cutting tools, such as tool bits and drill bits.
