There are many types and variations of the metal lathe today, each designed for a particular function and/or tolerance. Some of the more common types of lathes are: the center lathe which is the simplest of lathes as well as the largest; the bench lathe that is usually small enough to be mounted on a workbench; the turret lathe which allows multiple bits to be simultaneously engaged. Other less versatile lathes that are used for more specialized operations include the engine lathe, the tool room lathe, the capstan lathe and the multi-spindle lathe.

Computer technology has given the metal lathe a huge range of versatility, economy and ease of operation. The CNC lathe, a computer-operated machine, allows an operator to simply program a particular function of the machining process. With the press of a button, the CNC lathe will automatically set the proper speed of the spindle rotation and engage the designated number of machining bits at precisely the right angle and depth. Today, the CNC lathe is the most commonly used metal lathe.
