Ancient lathe is by hand or pedal, lathe
Rotate the workpiece by rope, and hand-held cutting tool. In 1797, the British mechanical inventor Maudsley created a modern lathe with a screwdriver carriage and switched gears in 1800 to change the feed speed and pitch of the threads being machined. In 1817, another Englishman, Roberts, used four stages of pulleys and back wheels to change the spindle speed. In 1845, Fitch of the United States invented the turret lathe to increase the degree of mechanization and automation. 1848, the United States appeared again turn lathe In 1873, the United States Spencer made a single-axis automatic lathe, and soon he made three-axis automatic lathe.
At the beginning of the 20th century there was a separate motor-driven lathe with a gearbox. After World War I, due to the needs of the military, automotive and other mechanical industries, various types of highly efficient automatic lathes and specialized lathes developed rapidly. In the late 1940s, lathes with hydraulic profiling units were promoted, while multi-tool lathes were also developed at the same time in order to increase the productivity of small batch workpieces. In the 1950s program-controlled lathes with punch cards, latch plates and dials were developed. CNC technology began to be used in lathes in the 1960s and was rapidly developed in the 1970s.
