A lathe is a machine tool that turns work pieces by rotating them about an axis of rotation using tools. It is frequently used in woodworking, metalworking and other similar industries, or when parts must be shaped with high precision. Usually the tool itself is held in a fixed position while the workpiece is rotated, but there are exceptions such as Morse tapers 〞 see lathe tools
A lathe can also be used to cut rounds or other shapes in metal. The most common type of lathe for cutting metals is the horizontal boring machine (HBM), which uses a helical cutting tool to make long continuous cuts in round stock. Another type of lathe is the vertical boring machine (VBM), which uses a helical cutting tool that cuts on an angle, which allows it to form complex shapes such as gears or pistons.
