As early as the era of ancient Egypt, a technique was invented for turning wood with a cutting tool while the workpiece rotated around its central axis. Initially, two upright posts served as supports for the wood; the elasticity of a tree branch was used to wind a rope around the workpiece, which was then rotated by pulling the rope-either by hand or foot-while the operator held the cutting tool to perform the cut. This ancient method gradually evolved into the "bow lathe": a rope was wrapped two or three times around a pulley and attached to a flexible, bow-shaped rod; pushing and pulling the bow back and forth caused the workpiece to rotate for turning. By the Middle Ages, the "treadle lathe" had been designed; it utilized a foot pedal to rotate a crankshaft and drive a flywheel, which in turn transmitted motion to the main spindle to spin the workpiece.
Ancient lathes relied on manual pulling or foot-pedaling to rotate the workpiece via a rope while the operator held the cutting tool to perform the machining.
In 1797, the British mechanical inventor Henry Maudslay created a modern lathe featuring a lead screw to drive the tool carriage. Born in 1771, Maudslay was a capable assistant to the inventor Joseph Bramah by the age of 18. The same year he left Bramah's employ, he built his first screw-cutting lathe-an all-metal machine featuring a tool carriage and a tailstock capable of moving along two parallel guide rails. Three years later, in his own workshop, Maudslay built a more refined lathe equipped with interchangeable gears, allowing for adjustments to the feed rate and the pitch of the threads being cut. In 1800, he adopted change gears to further enable the adjustment of feed rates and thread pitches. In 1817, another Briton, Richard Roberts, introduced a four-step pulley and back-gear mechanism to vary the spindle speed.
To enhance the level of mechanization and automation, the American inventor Stephen Fitch invented the turret lathe in 1845.
In 1848, the capstan lathe also appeared in the United States. In 1873, the American inventor Spencer built a single-spindle automatic lathe, followed shortly thereafter by a three-spindle model.
The early 20th century saw the emergence of lathes driven by individual motors and equipped with gear-based speed-change gearboxes.
Following World War I, the demands of the munitions, automotive, and other machinery industries drove the rapid development of various high-efficiency automatic lathes and specialized lathes. To boost productivity for small-batch production, lathes featuring hydraulic copying attachments gained widespread adoption in the late 1940s, a period that also saw the development of multi-tool lathes. The mid-1950s marked the development of program-controlled lathes utilizing punched cards, plugboards, and rotary switches. Numerical control (NC) technology was first applied to lathes in the 1960s and underwent rapid development from the 1970s onwards.
From the 1970s onwards, high-precision machine tools-exemplified by CNC lathes-began to rise in prominence.
