The term "turret lathe" without further qualification is still understood to refer to this type. The formative decades for this class of machine were the 1840s through 1860s, when the basic idea of mounting an indexable turret on a bench lathe or engine lathe was born, developed, and disseminated from the originating shops to many other factories.

By 1913 the company employed 100. In 1916 to 1917, Steinle extended the factory floor to the south, including the monitor roof. During World War I Steinle manufactured military supplies - using his turret lathes to manufacture five-inch naval guns in a separate 600-man factory on Atwood Avenue. Minor additions to the factory at 149 Waubesa ...
Its products, both turret lathes and instruments, played very prominent roles in the war efforts for both world wars. Warner & Swasey took part in the transition to numerical control and computer numerical control machine tools during the 1950s through 1970s, but like many other machine tool builders during those decades, it ultimately was ...
Tailstock, click on image to see naming of parts Tailstock used for drilling. A tailstock, also known as a foot stock, [1] is a device often used as part of an engineering lathe, wood-turning lathe, or used in conjunction with a rotary table on a milling machine.
Important early machine tools included the slide rest lathe, screw-cutting lathe, turret lathe, milling machine, pattern tracing lathe, shaper, and metal planer, which were all in use before 1840. [12] With these machine tools the decades-old objective of producing interchangeable parts was finally realized. An important early example of ...
The workpiece is held in the indexing head in the same manner as a metalworking lathe. This is most commonly a chuck but can include a collet fitted directly into the spindle on the indexing head, faceplate, or between centers. If the part is long then it may be supported with the help of an accompanying tailstock.
Indexing in reference to motion is moving (or being moved) into a new position or location quickly and easily but also precisely. When indexing a machine part, its new location is known to within a few hundredths of a millimeter (thousandths of an inch), or often even to within a few thousandths of a millimeter (ten-thousandths of an inch), despite the fact that no elaborate measuring or ...
