Lathe is the main tool used to turn the rotating workpiece of the lathe. On the lathe can also be used to drill bits, reaming drilling, reamer, taps, die and rolling tools, etc. for the corresponding processing.
The ancient lathe was made by pulling or pedaling the workpiece through the ropes, and cutting with a hand knife. In the 1797, the British mechanical inventor Maudsley created a modern lathe with a lead screw drive and switched gears in 1800 to change the feed speed and the pitch of the thread being processed. In 1817, another Englishman, Roberts, used a four-stage belt wheel and a back wheel mechanism to change the spindle speed. In order to improve mechanization of automation, 1845, the United States of the Philippines invented turret lathe.
1848, the United States again appeared back wheel lathe 1873, the United States of Spencer made a single spindle automatic lathe, and soon he was made into a three-axis automatic lathe. At the beginning of 20th century there was a lathe with a gear box driven by a separate motor. After the First World War, various efficient automatic lathes and specialized lathes developed rapidly due to the needs of arms, automobiles and other machinery industries. In order to improve the productivity of small batch workpiece, the lathe with hydraulic profiling device was popularized in the late 40, meanwhile, the lathe of multiple knives was also developed. The 50, the development of a perforated card, latch plate and Dial the code plate, such as the program control lathe. CNC technology in the 60 's began to be used in lathes, 70 after the rapid development.
