In machining, a metal lathe or metalworking lathe is 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 ...
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 ...
The first American turret lathe was invented by Stephen Fitch in 1845. [6] The archetypical turret lathe, and the first in order of historical appearance, is the horizontal-bed, manual turret lathe. The term "turret lathe" without further qualification is still understood to refer to this type.
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 ...
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 ...
For manual milling machines, there is less standardization, because a greater plurality of formerly competing standards exist. Newer and larger manual machines usually use NMTB tooling. This tooling is somewhat similar to CAT tooling but requires a drawbar within the milling machine. Furthermore, there are a number of variations with NMTB ...
Facing on a lathe (perpendicular to the axis of rotation), which is commonly used in turning and boring operations. Other operations remove material in ways similar to facing, for example, planing, shaping, and grinding, but these processes are not labeled by the term "facing."
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.
