Modern metal lathe A watchmaker using a lathe to prepare a component cut from copper for a watch. A lathe (/ l eɪ ð /) is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about ...
A view inside the enclosure of a CNC Swiss-style lathe/screw machine. A Swiss-style lathe is a specific design of lathe providing extreme accuracy (sometimes holding tolerances as small as a few tenths of a thousandth of an inch—a few micrometers). A Swiss-style lathe holds the workpiece with both a collet and a guide bushing. The collet sits ...
In metalworking and woodworking, an automatic lathe is a lathe with an automatically controlled cutting process. Automatic lathes were first developed in the 1870s and were mechanically controlled. From the advent of NC and CNC in the 1950s, the term automatic lathe has generally been used for only mechanically controlled lathes, although some ...
Jacques de Vaucanson (French: [jak də vocɑ̃sɔ̃]; February 24, 1709 – November 21, 1782) [1] was a French inventor and artist who built the first all-metal lathe. This invention was crucial for the Industrial Revolution. The lathe is known as the mother of machine tools, as it was the first machine tool that led to the invention of other ...
A turret lathe is a form of metalworking lathe that is used for repetitive production of duplicate parts, which by the nature of their cutting process are usually interchangeable. It evolved from earlier lathes with the addition of the turret, which is an indexable toolholder that allows multiple cutting operations to be performed, each with a ...
Today's South Bend Lathe corporation is the successor to the original South Bend Lathe Works, an American machine tool builder that for many decades was one of the most important builders [citation needed] of metalworking lathes in the U.S. and in the world. The South Bend Lathe Works was established in 1906 in South Bend, Indiana by identical ...
A screw-cutting lathe is a machine (specifically, a lathe) capable of cutting very accurate screw threads via single-point screw-cutting, which is the process of guiding the linear motion of the tool bit in a precisely known ratio to the rotating motion of the workpiece. This is accomplished by gearing the leadscrew (which drives the tool bit's ...
A lathe is a machine tool used principally for shaping pieces of metal, wood, or other materials by causing the workpiece to be held and rotated by the lathe while a tool bit is advanced into the work causing the cutting action. Lathes can be divided into three types for easy identification: engine lathe, turret lathe, and special purpose ...
