A lathe is a machine tool that primarily uses turning tools to perform machining on rotating workpieces. On the lathe, corresponding processing can also be carried out using drill bits, reamers, taps, dies, and knurled tools.
In ancient times, lathes relied on hand pulling or foot pedaling, rotating the workpiece through a rope, and holding a cutting tool for cutting. In 1797, British mechanical inventor Mozley created a modern lathe with a screw driven tool holder, and in 1800, AC gears were used to change the feed rate and the pitch of the processed threads.
After World War I, various efficient active lathes and specialized lathes were rapidly developed due to the needs of the military, automotive, and other mechanical industries. In order to improve the productivity of small batch workpieces, lathes with hydraulic profiling equipment were promoted in the late 1940s, and at the same time, multi tool lathes were also developed.
There are several types of lifting table milling machines, including universal, horizontal, and vertical, mainly used for processing small and medium-sized parts, with the widest application; The gantry milling machine includes gantry milling and boring machines, gantry milling and planing machines, and double column milling machines, all of which are used for processing large parts; The horizontal milling head of a single column milling machine can move along the column guide rail, and the workbench is fed longitudinally; The end milling head of a single arm milling machine can move horizontally along the cantilever guide rail, and the cantilever can also adjust the height along the column guide rail.
