machine tool which rotates the workpiece on its axis From Wikipedia, the free encyclopedia
A lathe is a type of machine used to shape things. Various kinds of work such as woodturning, metalworking, metal spinning, spin welding and glassworking use lathes. A lathe works by turning an object on an axis and applying a tool to shape it. Most lathes turn the workpiece on a horizontal axis; the potter's wheel uses a vertical axis. There are various types of lathe machine but horizontal lathes are used widely.
CNC (Computer numerical control) lathes can perform the same jobs more accurately than manual lathes. Lathes work by using accessories such as cutting tools and rests.
Examples of objects that can be made using a lathe are, candlestick holders, gun barrels, cue sticks and baseball bats.
The lathe is driven by a motor that rotates a blank of wood between two centres – the fork centre and the centre – that hold it in place. The machine rotates the wood and the user uses a variety of chisels to shape the wood by moving the chisels along a tool rest.
