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 ...
Lathes are the principal machine tool used in turning. Boring involves the machining of an internal surface of a hole to increase it diameter, this can be performed by either turning the workpiece on a lathe (also called internal turning), or a mill where a tool is rotated around the circumference of the hole.
Before about the beginning of the 19th century, these were used in pairs, and even screws of the same machine were generally not interchangeable. [13] Methods were developed to cut screw thread to a greater precision than that of the feed screw in the lathe being used. This led to the bar length standards of the 19th and early 20th centuries.
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 ...
In 1883, Junker and his business partner Anselme Marchal founded the company Junker et Cie. In the same year, Junker began producing automatic machines and was the first entrepreneur to bring mass-produced lathes onto the market. The lathes were mainly used to produce screws, due to the increasing demand from the watchmaking industry.
A wiper insert is an insert used in a milling machine or a lathe. It is designed for finished cutting, to give a smooth surface on the surface being cut. It uses special geometry to give a good finish on the workpiece at a higher-than-normal feedrate.
The company was founded in 1919 in Nagoya by Sadakichi Yamazaki as a small company making pots and pans. [4] During the 1920s it progressed through mat-making machinery to woodworking machinery to metalworking machine tools, especially lathes. [5]
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.
