The development of numerical control was the next major leap in the history of automatic lathes—and it is also what changed the paradigm of what the "manual versus automatic" distinction meant. Beginning in the 1950s, NC lathes began to replace manual lathes and cam-op screw machines, although the displacement of the older technology by CNC ...
Hartness 3x36 flat turret lathe with cross-sliding head, equipped for bar work, 1910 [1]. A turret lathe is a form of metalworking lathe that is used for repetitive production of duplicate parts, which by the nature of their cutting process are usually interchangeable.
A memoir that contains quite a bit of general history of the industry. Floud, Roderick C. (2006) [1976], The British Machine Tool Industry, 1850–1914, Cambridge, England: Cambridge University Press, ISBN 978-0-521-02555-3, LCCN 2006275684, OCLC 70251252. A monograph with a focus on history, economics, and import and export policy.
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 ...
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 ...
A lead screw is sometimes used with a split nut (also called half nut) which allows the nut to be disengaged from the threads and moved axially, independently of the screw's rotation, when needed (such as in single-point threading on a manual lathe). A split nut can also be used to compensate for wear by compressing the parts of the nut.
Early bow lathes and strap lathes were developed and used in Egypt and Rome. [3] The Chinese, Persians, and Arabs had their variations of the bow lathe. [4] Early lathe workers would sometimes use their bare feet to hold cutting tools in place while using their hands to power the lathe.
South Bend Lathe is a brand of machine tools. Today's South Bend Lathe corporation is the successor to the original South Bend Lathe Works , an American machine tool builder that for many decades was one of the most important builders [ citation needed ] of metalworking lathes in the U.S. and in the world.
