Lathe and milling machines

Types of lathes and milling machines

Both **lathes** and **milling machines** are used in the machining process to remove material from a workpiece to achieve the desired shape and size. These machines are commonly used in industries such as automotive, aerospace, and construction. The main types of lathes are categorized based on the axis around which they rotate the workpiece: parallel to the bed (usually the z-axis) or perpendicular to the bed (usually the x-axis). The types of milling machines are distinguished by the orientation of the spindle, such as horizontal, vertical, or universal machines.

• Metal lathe machines

A metal lathe machine is used to shape cylindrical material by rotating the workpiece against cutting tools. The main types are engine lathes, turret lathes, and special-purpose lathes. An engine lathe is the most common type of metal lathe machine. It is operated manually and is suitable for light manufacturing and repairing tasks. Engine lathes have a single spindle that can be rotated at different speeds to cut various metals. On the other hand, turret lathes are more suitable for mass production because they have an automated turret to cut the workpiece in various ways. In most cases, turret lathes are used to produce small parts. A special-purpose lathe is designed to perform specific machining tasks and is not as versatile as other lathes.

• Milling machines

Like **lathes**, **milling machines** are used to cut workpieces made of various materials by rotating multiple cutting tools around several axes. The main types are horizontal, vertical, and universal milling machines. Horizontal milling machines have a horizontally oriented spindle and work well for cutting metal from the sides of a workpiece. In contrast, a vertical milling machine has a vertically oriented spindle and can be used to cut metal from the top of a workpiece. Universal milling machines are more flexible than vertical or horizontal milling machines. They have a spindle that can be oriented in any direction, which is suitable for various cutting tasks.
