Sander Kösters
A sander is a power tool used to smooth surfaces by abrasion with sandpaper. Sanders have a means to attach the sandpaper and a mechanism to move it rapidly contained within a housing with means to handhold it or fix it to a workbench. Woodworking sanders are usually powered electrically, and those used in auto-body repair work are usually powered by compressed air. There are many different types of sanders for different purposes. Multipurpose power tools and electric drills may have sander attachments. Types Types of power sanders include: * Belt sander (hand-held or stationary) * Detail sander: A hand-held sander that uses a small vibrating head with a triangular piece of sandpaper attached. Used for sanding corners and very tight spaces. Also known as "mouse" or "corner" sanders. * Disc sander: A disc sander is most commonly implemented as a stationary machine that consists of a replaceable circular shaped sandpaper attached to a wheel turned by an electric motor or compr ...

Random Orbit Sander
A random orbital sander (also known as a palm sander) is a hand-held power tool which sands in a random-orbit action. That is, in constant irregular overlapping circles. This technology was first commercially utilized in 1968 by Rupes Tools. Random orbital sanders combine the speed and aggressiveness of a belt sander with the ability to produce a finer finish than that available from a standard, slow speed orbital finishing sander. Random orbital sanders generally come in three different types: electric powered, air powered, and orbital floor sanders. The electric and air powered orbital sanders are handheld, while the floor orbital sanders are large machines that roll. The random orbit sanding pattern is produced by simultaneously spinning the sanding disk and moving it in small ellipses. This ensures that no single part of the abrasive material travels the same path twice during the same rotation. Because of this random sanding action, the tool does not leave swirl marks, and i ...

Rolodex
A Rolodex is a rotating card file device used to store a contact list. Its name, a portmanteau of the words "rolling" and "index", has become somewhat genericized for any personal organizer performing this function, or as a metonym for a total accumulation of business contacts. In this usage, it has generally come to describe an effect or characteristic of the small-world network of a business's investors, board of directors, or the value of a CEO's contacts, or in organizational structure. Models have been exhibited in the Smithsonian Institution. History The Rolodex was invented in 1956 by Danish engineer Hildaur Neilsen, the chief engineer of Arnold Neustadter Arnold Neustadter (25 August 1910 – 17 April 1996) was an American inventor An invention is a unique or novel device, method, composition, idea, or process.

Metalworking Tools
Metalworking is the process of shaping and reshaping metals in order to create useful objects, parts, assemblies, and large scale structures. As a term, it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges, down to precise engine parts and delicate jewellery. The historical roots of metalworking predate recorded history; its use spans cultures, civilizations and millennia. It has evolved from shaping soft, native metals like gold with simple hand tools, through the smelting of ores and hot forging of harder metals like iron, up to and including highly technical modern processes such as machining and welding. It has been used as an industry, a driver of trade, individual hobbies, and in the creation of art; it can be regarded as both a science and a craft. Modern metalworking processes, though diverse and specialized, can be categorized into one of three broad areas known as forming, cuttin ...

Flapwheel
A flapwheel and the related flap disk is an abrasive disk, used for metal finishing. Unlike the simpler flat disks, made from a circular flat sheet of a coated abrasive, a flapwheel is made of multiple overlapping small pieces or 'flaps', bonded to a central hub. Advantages The advantages of a flapwheel over a traditional disk are twofold: * The separate flaps each attack the workpiece surface at a slightly different angle, and this varies slightly with tool angle. This avoids the common problem with flat sheets, where they produce repeated identical scratches. * Abrasive wear is distributed more evenly across the flaps, and through the length of each flap. Flaps wear from their outer ends and the sheet carrier cuts back as the abrasive coating is worn away. The wheel remains useful even as the flaps erode. Compared to flat sheets, that are discarded after only a small area of the abrasive is truly worn-out, this is a much more efficient use of the abrasive material. Developmen ...

Rust
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron. Given sufficient time, any iron mass, in the presence of water and oxygen, could eventually convert entirely to rust. Surface rust is commonly flaky and friable, and provides no passivational protection to the underlying iron unlike other metals such as aluminum, copper, and tin which form stable oxide layers. ''Rusting'' is the common term for corrosion of elemental iron and its alloys such as steel. Many other metals undergo similar corrosion, but the resulting oxides are not commonly called "rust". Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Other forms of rust include the result of r ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, submarine, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or Mast (sailing), mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box, in the case of scow barges, to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bot ...

KC-10 Extender
The McDonnell Douglas KC-10 Extender is an American tanker and cargo aircraft that was operated by the United States Air Force (USAF) from 1981 to 2024. A military version of the three-engine DC-10 airliner, the KC-10 was developed from the Advanced Tanker Cargo Aircraft Program. It incorporates military-specific equipment for its primary roles of aerial refueling and transport. It was developed to supplement the KC-135 Stratotanker following experiences in Southeast Asia and the Middle East. The KC-10 was the second McDonnell Douglas transport aircraft to be selected by the Air Force following the C-9. A total of 60 KC-10s were produced for the USAF. The Royal Netherlands Air Force operated two similar tankers from 1995 to 2021 designated ''KDC-10'' that were converted from used civilian DC-10, instead of purpose built aircraft. The KC-10 played a key role in the mobilization of US military assets, taking part in overseas operations far from home. These aircraft performed a ...

Planer (metalworking)
A planer is a type of metalworking machine tool that uses linear relative motion between the workpiece and a single-point cutting tool to cut the work piece.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' p. 73, Cypress, CA, 2013. . A planer is similar to a shaper, but larger, and with workpiece moving, whereas in a shaper the cutting tool moves. Applications Linear planing The most common applications of planers and shapers are linear-toolpath ones, such as: * Generating accurate flat surfaces. (While not as precise as grinding, a planer can remove a tremendous amount of material in one pass with high accuracy.) * Cutting slots (such as keyways). * It is even possible to do work that might now be done by wire EDM in some cases. Starting from a drilled or cored hole, a planer with a boring-bar type tool can cut internal features that do not lend themselves to milling or boring (such as irregularly shaped holes with tig ...

Power Tool
A power tool is a tool that is actuator, actuated by an additional engine, power source and mechanism (engineering), mechanism other than the solely manual labour, manual labor used with hand tools. The most common types of power tools use electric motors. Internal combustion engines and compressed air are also commonly used. Tools directly driven by working animal, animal power are not generally considered power tools. Power tools can produce large amounts of particulates, including ultrafine particles. Airborne particulate matter is a Group 1 carcinogen. Uses Power tools are used in industry, in construction, in renovation, in the garden, for Homemaking, housework tasks such as Outline of food preparation#Food preparation techniques, cooking, housekeeping, cleaning, and Do it yourself, around the house for purposes of driving (fasteners), drilling, saw, cutting, shaping, sander, sanding, Grinding (abrasive cutting), grinding, router (woodworking), routing, polishing, painting, me ...

Mesh (scale)
Mesh is a measurement of particle size often used in determining the particle-size distribution of a granular material A granular material is a conglomeration of discrete solid, macroscopic scale, macroscopic particles characterized by a loss of energy whenever the particles interact (the most common example would be friction when granulation, grains collide). T .... For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh. A commercial peanut buyer might use a test like this to determine if a batch of peanuts has too many broken pieces. This type of test is common in some industries, and, to facilitate uniform testing methods, several standardized mesh series have been established. Metal surfaces mechanically polished are designated as having a mechanical finish related to the abrasive used. Many mesh siz ...

Machine
A machine is a physical system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, known today as mechanical advantage. Modern machines are complex systems that consist of structural elements, mechanisms and contr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
