Lathe machines are used to shape various materials and perform numerous operations such as sanding, deformation, cutting, facing, knurling, drilling, turning, and much more. Lathes are capable of producing items with very fine finishes so they are often used for finishing work where a high degree of precision is required. Shaping can be done on any type of lathe but it is most commonly done on spindle-type lathes because they have many different tools that can be quickly attached to and removed from the shaft. These tools include brushes, rollers, pins, and cutters. Spur-type and face-type lathes are also useful for shaping applications because each tool can hold a large amount of stock while it is being worked on. Face-type lathes are particularly good at creating complex shapes because several different faces can be used together like scissors to cut away material. There are two types of spindle-type lathes: single-spindle and multiple-spindle. With single-spindle lathes, only one tool can be mounted on the spindle at a time. This means that if you want to change tools, you must first remove the old tool before you can install the new one.
