Turret Lathe
A turret lathe is a form of lathe (metal), metalworking lathe that is used for repetitive production of duplicate parts, which by the nature of their cutting process are usually interchangeable parts, interchangeable. It evolved from earlier lathes with the addition of the ''turret'', which is an indexing (motion), indexable toolholder that allows multiple cutting operations to be performed, each with a different Cutting tool (machining), cutting tool, in easy, rapid succession, with no need for the operator to perform set-up tasks in between (such as installing or uninstalling tools) or to control the toolpath. The latter is due to the toolpath's being controlled by the machine, either in jig (tool), jig-like fashion, via the mechanical limits placed on it by the turret's slide and stops, or via Digital electronics, digitally-directed servomechanisms for computer numerical control lathes. The name derives from the way early turrets took the general form of a flattened cylindrical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colt's Manufacturing Company
Colt's Manufacturing Company, LLC (CMC, formerly Colt's Patent Firearms Manufacturing Company) is an American firearms manufacturer, founded in 1855 by Samuel Colt that has become a subsidiary of Czech holding company Colt CZ Group. It is the successor corporation to Colt's earlier firearms-making efforts, which started in 1836. Colt is known for the engineering, production, and marketing of firearms, especially during the century from 1850 through World War I, when it dominated its industry and was a seminal influence on manufacturing technology. Colt's earliest designs played a major role in the popularization of the revolver and the shift away from single-shot pistols. Although Samuel Colt did not invent the revolver, his designs resulted in the first very successful model. The most famous Colt products include the Colt Walker, made in 1847 in the facilities of Eli Whitney Jr., the Colt Single Action Army, the Colt Python, and the Colt M1911 pistol, which is the longest ...

Machine Tools
A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformations. Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the workpiece and provide a guided movement of the parts of the machine. Thus, the relative movement between the workpiece and the cutting tool (which is called the toolpath) is controlled or constrained by the machine to at least some extent, rather than being entirely "offhand" or " freehand". It is a power-driven metal cutting machine which assists in managing the needed relative motion between cutting tool and the job that changes the size and shape of the job material. The precise definition of the term ''machine tool'' varies among users. While all machine tools are "machines that help people to make things", not all factory machines are machine tools. Today machine tools are typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer
A computer is a machine that can be Computer programming, programmed to automatically Execution (computing), carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as Computer program, ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the Computer hardware, hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots.

World War II
World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks in World War II, Tanks and Air warfare of World War II, aircraft played major roles, enabling the strategic bombing of cities and delivery of the Atomic bombings of Hiroshima and Nagasaki, first and only nuclear weapons ever used in war. World War II is the List of wars by death toll, deadliest conflict in history, causing World War II casualties, the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease.

World War I
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting took place mainly in European theatre of World War I, Europe and the Middle Eastern theatre of World War I, Middle East, as well as in parts of African theatre of World War I, Africa and the Asian and Pacific theatre of World War I, Asia-Pacific, and in Europe was characterised by trench warfare; the widespread use of Artillery of World War I, artillery, machine guns, and Chemical weapons in World War I, chemical weapons (gas); and the introductions of Tanks in World War I, tanks and Aviation in World War I, aircraft. World War I was one of the List of wars by death toll, deadliest conflicts in history, resulting in an estimated World War I casualties, 10 million military dead and more than 20 million wounded, plus some 10 million civilian de ...

Screw Machine (automatic Lathe)
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 manufacturers (e.g., DMG Mori and Tsugami) market Swiss-type CNC lathes as 'automatic'. CNC has not yet entirely displaced mechanically automated lathes, as although no longer in production, many mechanically automated lathes remain in service. General nomenclature The term "automatic lathe" is still often used in manufacturing in its earlier sense, referring to automated lathes of non- CNC types. The first automatic lathes were mechanically automated and controlled by cams or tracers and pantographs. Thus, before electronic automation via numerical control, the "automatic" in the term "automatic machine tool" always referred implic ...

Cuckoo Clock
A cuckoo clock is a type of clock, typically pendulum clock, pendulum driven, that striking clock, strikes the hours with a sound like a common cuckoo call and has an automated cuckoo bird that moves with each note. Some move their wings and open and close their beaks while leaning forwards, whereas others have only the bird's body leaning forward. The mechanism to produce the cuckoo call has been in use since the middle of the 18th century and has remained almost without variation. It is unknown who invented the cuckoo clock and where the first one was made. It is thought that much of its development and evolution was made in the Black Forest area in southwestern Germany (in the modern state of Baden-Württemberg), the region where the cuckoo clock was popularized and from where it was exported to the rest of the world, becoming world-famous from the mid-1850s on. Today, the cuckoo clock is one of the favourite souvenirs of travellers in Germany, Switzerland, Austria and Eastern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chuck (engineering)
A chuck is a specialized type of clamp (tool), clamp used to hold an object with rotational symmetry, radial symmetry, especially a cylinder (geometry), cylinder. In a drill, a Milling (machining), mill and a transmission (mechanics), transmission, a chuck holds the rotating tool bit, tool; in a lathe, it holds the rotating workpiece. Chucks commonly use jaws to hold the tool or workpiece. The jaws are typically arranged in a radially symmetrical pattern like the points of a star (polygon), star. Jawed chucks may require a Wrench#Other types of keys, wrench-like device called a ''chuck key'' to be tightened or loosened, but other jawed chucks may be tightened or loosened by hand force alone, offering convenience at the expense of gripping force. Chucks on some lathes have jaws that move independently, allowing them to hold irregularly shaped objects. More complex designs might include specially shaped jaws, greater numbers of jaws, or quick-release mechanisms. Instead of jaws, a ...

Cam (mechanism)
A cam is a rotating or sliding piece in a linkage (mechanical), mechanical linkage used especially in transforming rotary motion into linear motion. It is often a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path. The cam can be a simple tooth, as is used to deliver pulses of power to a steam hammer, for example, or an Eccentric (mechanism), eccentric disc or other shape that produces a smooth reciprocating (back and forth) motion in the ''Cam follower, follower'', which is a lever making contact with the cam. A cam timer is similar, and these were widely used for electric machine control (an electromechanical timer in a washing machine being a common example) before the advent of inexpensive electronics, microcontrollers, integrated circuits, programmable logic controllers and digital control. Camshaft The cam can be seen as a device that converts rotational mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
