Modern metal lathe A watchmaker using a lathe to prepare a component cut from copper for a watch. A lathe (/ l eɪ ð /) is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about ...
A view inside the enclosure of a CNC Swiss-style lathe/screw machine. A Swiss-style lathe is a specific design of lathe providing extreme accuracy (sometimes holding tolerances as small as a few tenths of a thousandth of an inch—a few micrometers). A Swiss-style lathe holds the workpiece with both a collet and a guide bushing. The collet sits ...
Brown & Sharpe Single Spindle screw machine. Model #2 Square Base, four-slide machine. 1 1 ⁄ 2 cap or 1 3 ⁄ 4 Air Feed.. Screw machines, being the class of automatic lathes for small- to medium-sized parts, are used in the high-volume manufacture of a vast variety of turned components.
Important early machine tools included the slide rest lathe, screw-cutting lathe, turret lathe, milling machine, pattern tracing lathe, shaper, and metal planer, which were all in use before 1840. [12] With these machine tools the decades-old objective of producing interchangeable parts was finally realized. An important early example of ...
A lathe is a machine tool used principally for shaping pieces of metal, wood, or other materials by causing the workpiece to be held and rotated by the lathe while a tool bit is advanced into the work causing the cutting action. Lathes can be divided into three types for easy identification: engine lathe, turret lathe, [5] and special purpose ...
Large vertical lathe used for machining water turbines, with a face in the order of 10 to 15 meters in diameter (see worker on top of turbine for scale). A vertical lathe is a lathe where the axis of rotation is oriented vertically, unlike most conventional lathes which are oriented horizontally.
