Perlée
Perlée and perlage are French words for ''pearl pattern'', a decorative metallic finish consisting of a pattern of small circles (''pearls'') applied to a surface by grinding. It is mostly used in the automotive and watchmaking industries as an indicator of expensive craftsmanship, particularly if applied by hand rather than machine. Perlée in the watchmaking industry Watch components that are given a perlée pattern may include the movement main plate and bridges, the inside of the watch case and the watch-case bottom. The perlée patterned parts of a wrist watch are commonly invisible from the outside except if the watch has a transparent casing or deliberately exposed internal parts. Further grinding patterns used by watchmakers include the ''clavus'' pattern, also known by the French term ''oeil-de-perdrix'' (partridge eye). Perlée in the automotive and aviation industries The automotive industry has used perlée patterns on surfaces such as car dashboards since its inf ...

Engine Turning
Engine turning is a form of ornamental turning. The finishing technique may use lathes or engines to produce a pattern. Aluminium is often the metal chosen to decorate. The technique has been used in various industries, including aircraft and document verification. Description Engine turning is a form of ornamental turning. The technique geometrically applies a single-point cutting tool to produce a decorative metal surface finish pattern. Traditionally, engine turning referred to Guilloché engraving. In the 20th century, it also came to refer to the different process of ' (also known as spotting, jewelling, perlage), which is a fine geometric pattern of overlapping circles abraded onto the surface. Equipment Guilloché engine turning may be done with various machines, including rose engines, straight-line engines, brocade engines, and ornamental turning lathes. Perlage uses an abrasive rotating disk or dowel. Material Aluminium is often the metal chosen to decorat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watchmaking
A watchmaker is an artisan who makes and repairs watches. Since a majority of watches are now factory-made, most modern watchmakers only repair watches. However, originally they were master craftsmen who built watches, including all their parts, by hand. Modern watchmakers, when required to repair older watches, for which replacement parts may not be available, must have fabrication skills, and can typically manufacture replacements for many of the parts found in a watch. The term clockmaker refers to an equivalent occupation specializing in clocks. Most practising professional watchmakers service current or recent production watches. They seldom fabricate replacement parts. Instead they obtain and fit factory spare parts applicable to the watch brand being serviced. The majority of modern watchmakers, particularly in Switzerland and other countries in Europe, work directly for the watchmaking industry and may have completed a formal watchmaking degree at a technical school ...

Bugatti Veyron 16
Automobiles Ettore Bugatti was a German then French manufacturer of high-performance automobiles. The company was founded in 1909 in the then-German city of Molsheim, Alsace, by the Italian-born industrial designer Ettore Bugatti. The cars were known for their design beauty and numerous race victories. Famous Bugatti automobiles include the Type 35 Grand Prix cars, the Type 41 "Royale", the Type 57 "Atlantic" and the Type 55 sports car. The death of Ettore Bugatti in 1947 proved to be a severe blow to the marque, and the death of his son Jean in 1939 meant that there was no successor to lead the factory. With no more than about 8,000 cars made, the company struggled financially, and it released one last model in the 1950s before eventually being purchased for its airplane parts business in 1963. In 1987, an Italian entrepreneur bought the brand name and revived it as Bugatti Automobili S.p.A. A movie about the founding of the French car manufacturer Bugatti is being prod ...

Golden Age Of Aviation
Sometimes dubbed the Golden Age of Aviation, the period in the history of aviation between the end of World War I (1918) and the beginning of World War II (1939) was characterised by a progressive change from the slow wood-and-fabric biplanes of World War I to fast, streamlined metal monoplanes, creating a revolution in both commercial and military aviation. By the outbreak of World War II in 1939 the biplane was all but obsolete. This revolution was made possible by the continuing development of lightweight aero engines of increasing power. The jet engine also began development during the 1930s but would not see operational use until later. During this period civil aviation became widespread and many daring and dramatic feats took place such as round-the-world flights, air races and barnstorming displays. Many commercial airlines were started during this period. Long-distance flights for the luxury traveller became possible for the first time; the early services used airships ...

9 (nine) is the natural number following and preceding . Evolution of the Hindu–Arabic digit Circa 300 BC, as part of the Brahmi numerals, various Indians wrote a digit 9 similar in shape to the modern closing question mark without the bottom dot. The Kshatrapa, Andhra and Gupta started curving the bottom vertical line coming up with a -look-alike. How the numbers got to their Gupta form is open to considerable debate. The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the sign @ encircles a lowercase ''a''. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. Soon, all that was left of the 3-look-alike was a squiggle. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic. While the shape of the glyph for the digit 9 has an ascender in most modern typefa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guilloché
Guilloché (), or guilloche (), is a decorative technique in which a very precise, intricate and repetitive pattern is mechanically engraved into an underlying material via engine turning, which uses a machine of the same name. Engine turning machines may include the rose engine lathe and also the straight-line engine. This mechanical technique improved on more time-consuming designs achieved by hand and allowed for greater delicacy, precision, and closeness of line, as well as greater speed. The term ''guilloche'' is also used more generally for repetitive architectural patterns of intersecting or overlapping spirals or other shapes, as used in the Ancient Near East, classical Greece and Rome and neo-classical architecture, and Early Medieval interlace decoration in Anglo-Saxon art and elsewhere. Medieval Cosmatesque stone inlay designs with two ribbons winding around a series of regular central points are very often called guilloche. These central points are often blank, ...
