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 ...
Jacques de Vaucanson (French: [jak də vocɑ̃sɔ̃]; February 24, 1709 – November 21, 1782) [1] was a French inventor and artist who built the first all-metal lathe.This invention was crucial for the Industrial Revolution.
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 ...

Then green sand castings are used to make a metal lathe. The lathe is the first machine built since it can be used to help build itself. The lathe and foundry are then used to make more complicated machine tools. The books in the series are, in the suggested sequence of construction: The Charcoal Foundry; The Metal Lathe; The Metal Shaper
Henry Maudslay's early screw-cutting lathes of circa 1797 and 1800.. A screw-cutting lathe is a machine (specifically, a lathe) capable of cutting very accurate screw threads via single-point screw-cutting, which is the process of guiding the linear motion of the tool bit in a precisely known ratio to the rotating motion of the workpiece.
The history of automatic lathes in industrial contexts began with screw machines, and that history can only be truly understood within the context of screw making in general. Thus the discussion below begins with a simple overview of screw making in prior centuries, and how it evolved into 19th-, 20th-, and 21st-century practice.
1818 Profile lathe. A lathe is an adjustable horizontal metal rail and a tool rest, between the material and the operator which accommodates the positioning of shaping tools. With wood, it is common practice to press and slide sandpaper against the still-spinning object after shaping it to smooth the surface.
