The birth of a variety of special lathe in order to improve the degree of mechanization and automation of drilling equipment, in 1845, the US Fitch invention turret lathe; CNC drilling equipment in 1848, the United States has emerged back wheel lathe; in 1873, the United States, Spencer made A single spindle automatic lathes, and soon he was made of three-axis CNC machine tools since moving lathe; the early 20th century by a separate motor-driven lathe with a gear transmission. Due to the invention of high-speed tool steel and electrical applications drilling equipment, lathes and constantly improve, and finally reached the modern level of speed and accuracy. After World War I, due to the need of arms, vehicles and other machinery industry, a variety of specialized and efficient automatic lathes and lathe rapidly. In order to improve the productivity of small quantities of the workpiece, the late 1940s drilling equipment manufacturers, lathes with hydraulic copying device to get promotion, meanwhile, have also been developed multi-tool lathe. In the 1950s, the development of a program-controlled lathe with punch cards, the latch plate and dip tray and the like. CNC technology in the 1960s for the lathe, developed rapidly after the 1970s. According to the machine movement in the cutting process to distinguish between the role of the cutting movement divided into the main movement and feed movement. Main sport: sport is working to form a cutting tool or the main power consumption. Feed motion: the workpiece is excess material is removed continuously working movement. Cutting process is only one main movement, the feed movement may be more than one. Main movement and feed movement were completed by the tool or workpiece, the tool can also be done individually. In addition to cutting machine motion movement, and some auxiliary work to achieve the cutting process and the machine must be assisted movement.
