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 ...
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 ...
As with CNC milling machines, CNC routers can be controlled directly by manual programming, but CAD/CAM allows wider possibilities for contouring, speeding up the programming process and in some cases creating programs whose manual programming would be impractical. On some controllers the G-code can be loaded as a vector file on the router ...
The name bench lathe implies a version of this class small enough to be mounted on a workbench (but still full-featured, and larger than mini-lathes or micro-lathes). The construction of a center lathe is detailed above, but depending on the year of manufacture, size, price range or desired features, even these lathes can vary widely between ...
Lathe: Cuts workpieces while they are rotated. Makes fast, precision cuts, generally using indexable tools and drills. Effective for complicated programs designed to make parts that would be unfeasible to make on manual lathes. Similar control specifications to CNC mills and can often read G-code. Generally have two axes (X and Z), but newer ...
The closer on a manual lathe is either lever-style or handwheel-style. The closer on a CNC lathe is powered (electric, hydraulic, or pneumatic), and it may be controlled by various means: a foot pedal that the operator steps on when desired; a line in the program (for opening and closing under program control); or a button on the control panel.
