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 historical roots of metalworking predate recorded history; its use spans cultures, civilizations and millennia. It has evolved from shaping soft, native metals like gold with simple hand tools, through the smelting of ores and hot forging of harder metals like iron , up to and including highly technical modern processes such as machining ...
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.
A metal lathe is an example of a machine tool. A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformations. Machine tools employ some sort of tool that does the cutting or shaping.
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
