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.
His most influential invention was the screw-cutting lathe. The machine, which created uniformity in screws and allowed for the application of interchangeable parts (a prerequisite for mass production), was a revolutionary development necessary for the Industrial Revolution. [15]
Screw-cutting lathes fed into the just-dawning evolution of modern machine shop practice, whereas the wood-screw-making machines fed into the just-dawning evolution of the modern hardware industry, that is, the concept of one factory supplying the needs of thousands of customers, who consumed screws in growing quantities for carpentry, cabinet ...
David Wilkinson (January 5, 1771 – February 3, 1852) [1] was a U.S. mechanical engineer who invented a lathe for cutting screw threads, which was extremely important in the development of the machine tool industry in the early 19th century.
The four lathes (A, B, C, and T) were dimensionally identical but with different features. Model A was the top of the line with the screw-cutting gearbox. Model B was next with power cross feed and manual gear change for screw cutting. Model C had manual cross-feed and manual gear change for screw cutting. Model T was the Training lathe.
A screw machine may refer to a: Screw machine (automatic lathe), a small- to medium-sized automatic lathe that is mechanically automated via cams; Screw machine (turning center), a small- to medium-sized turning center that is electronically automated via CNC; Screw-cutting lathe; Turret lathe, now rarely called screw machines
