Turning Machines - Lathe Maintenance
Machine Types Home
The engine lathe is a precision machine tool and must be treated with great care. Regular cleaning and maintenance will help to assure that the lathe will maintain its service life and accuracy for many years. This unit will cover basic lathe maintenance. The procedures you find within this document should be able to be performed by apprentice or beginning machine tool students. Lathe maintenance that requires more extensive disassembly should only be done by, or under the supervision of, qualified personnel.

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.

Center lathe with DRO and chuck guard. Size is 460 mm swing x 1000 mm between centers
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.
