Kennametal
Kennametal, Inc. is a manufacturer of high-performance cutting tools and engineered components used in the aerospace, defense, transportation and oil and gas drilling industries. Its customer base is global. History Kennametal was founded in 1938 by Philip M. McKenna in the Latrobe, Pennsylvania area. The company evolved from Vanadium Alloys Steel Company (VASCO), founded in 1910 by the McKenna family with its headquarters in Latrobe, Pennsylvania. While research director of VASCO, metallurgist Philip McKenna developed and received a patent for a tungsten-titanium carbide composition. McKenna formed Kennametal, Inc. for the purpose of marketing this alloy. The company's original flagship product, known as "Kennametal", was introduced in the late 1930s. It was described as "much harder than the hardest tool steel," which enabled high-rate steel cutting not possible previously. In July 1940, Kennametal of Canada Ltd. was organized for the purpose of "manufacturing Kennametal, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stellite
Stellite alloys are a range of cobalt-chromium alloys designed for wear resistance. "Stellite" is also a registered trademark of Kennametal Inc. and is used in association with cobalt-chromium alloys. History Stellite was invented by Elwood Haynes in the early 1900s, initially as a material for making cutlery that would not stain or require constant cleaning. He was granted a patent for two specific alloys in 1907, and for two related ones in 1912; once he had these four patents he went into the business of producing his metal alloys. In the early 1920s, after considerable success during World War I in sales of cutting tools and high-speed machine tools made from Stellite, Haynes's company was bought by Union Carbide, becoming its "Stellite division", and continued to develop other alloys as well. The company was sold again in 1970 to Cabot Corporation, and in 1985 Cabot sold off the Stellite portion of the business. The Stellite trademark was acquired by Kennametal in 2012. Co ...

Tap And Die
In the context of threading, taps and dies are the two classes of tools used to create screw threads. Many are cutting tools; others are forming tools. A tap is used to cut or form the female portion of the mating pair (e.g. a nut). A die is used to cut or form the male portion of the mating pair (e.g. a bolt). The process of cutting or forming threads using a tap is called ''tapping'', whereas the process using a die is called ''threading''. Both tools can be used to clean up a thread, which is called ''chasing''. However, using an ordinary tap or die to clean threads generally removes some material, which results in looser, weaker threads. Because of this, machinists generally clean threads with special taps and dies—called '' chasers''—made for that purpose. Chasers are made of softer materials and don't cut new threads. However they still fit tighter than actual fasteners, and are fluted like regular taps and dies so debris can escape. Car mechanics, for example, use ch ...

Rail Transport
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in railway track, tracks, which usually consist of two parallel steel railway track, rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and rail freight transport, freight transport globally, thanks to its Energy efficiency in transport, energy efficiency and potentially high-speed rail, high speed.Rolling stock on rails generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by Diesel locomotive, diesel or Electric locomotive, electric locomotives. While railway transport is capital intensity, capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milling Cutter
Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools). They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutter's shape (e.g., a form tool such as a hobbing cutter). Features Milling cutters come in several shapes and many sizes. There is also a choice of coatings, as well as rake angle and number of cutting surfaces. * Shape: Several standard shapes of milling cutters are used in industry today, which are explained in more detail below. * Flutes / teeth: The flutes of the milling bit are the deep helical grooves running up the cutter, while the sharp blade along the edge of the flute is known as the tooth. The tooth cuts the material, and chips of this material are pulled up the flute by the rotation of the cutter. There is almost always one tooth per flute, but some cutters have two teeth per flute.

Tool Bit
In machining, a tool bit is a non-rotary cutting tool used in metal lathes, shapers, and planers. Such cutters are also often referred to by the set-phrase name of single-point cutting tool, as distinguished from other cutting tools such as a saw or water jet cutter. The cutting edge is ground to suit a particular machining operation and may be resharpened or reshaped as needed. The ground tool bit is held rigidly by a tool holder while it is cutting. Geometry Back rake is to help control the direction of the chip, which naturally curves into the work due to the difference in length from the outer and inner parts of the cut. It also helps counteract the pressure against the tool from the work by pulling the tool into the work. Side rake along with back rake controls the chip flow and partly counteracts the resistance of the work to the movement of the cutter and can be optimized to suit the particular material being cut. Brass for example requires a back and side rake of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tipped Tool
A tipped tool is any cutting tool in which the cutting edge consists of a separate piece of material that is brazed, welded, or clamped onto a body made of another material. In the types in which the cutter portion is an indexable part clamped by a screw, the cutters are called inserts (because they are inserted into the tool body). Tipped tools allow each part of the tool, the shank and the cutter(s), to be made of the material with the best properties for its job. Common materials for the cutters (brazed tips or clamped inserts) include cemented carbide, polycrystalline diamond, and cubic boron nitride. Tools that are commonly tipped include milling cutters (such as end mills, face mills, and fly cutters), tool bits, router bits, and saw blades (especially the metal-cutting ones). Advantages and disadvantages The advantage of tipped tools is only a small insert of the cutting material is needed to provide the cutting ability. The small size makes manufacturing of the ins ...

Consolidation (business)
In business, consolidation or amalgamation is the merger and acquisition of many smaller companies into a few much larger ones. In the context of financial accounting, ''consolidation'' refers to the aggregation of financial statements of a group company as consolidated financial statements. The taxation term of consolidation refers to the treatment of a corporate group, group of companies and other entities as one entity for tax purposes. Under the Halsbury's Laws of England, ''amalgamation'' is defined as "a blending together of two or more undertakings into one undertaking, the shareholders of each blending company, becoming, substantially, the shareholders of the blended undertakings. There may be amalgamations, either by transfer of two or more undertakings to a new company or the transfer of one or more companies to an existing company". Overview Consolidation is the practice, in business, of legally combining two or more organizations into a single new one. Upon consolidati ...

Cutting Tool (machining)
Cutting is the separation or opening of a physical object, into two or more portions, through the application of an acutely directed force. Implements commonly used for wikt:cut, cutting are the knife and saw, or in medicine and science the scalpel and microtome. However, any sufficiently sharp object is capable of cutting if it has a hardness sufficiently larger than the object being cut, and if it is applied with sufficient force. Even liquids can be used to cut things when applied with sufficient force (see water jet cutter). Cutting is a compression (physical), compressive and shearing (physics), shearing phenomenon, and occurs only when the total stress (physics), stress generated by the cutting implement exceeds the ultimate Strength of materials, strength of the material of the object being cut. The simplest applicable equation is: :\text = or \tau=\frac The stress generated by a cutting implement is directly proportional to the force with which it is applied, and ...

Fixture (tool)
A fixture is a work-holding or support device used in the manufacturing industry. Fixtures are used to securely locate (position in a specific location or orientation) and support the work, ensuring that all parts produced using the fixture will maintain conformity and interchangeability. Using a fixture improves the economy of production by allowing smooth operation and quick transition from part to part, reducing the requirement for skilled labor by simplifying how workpieces are mounted, and increasing conformity across a production run. Compared with a jig A fixture differs from a jig in that when a fixture is used, the tool must move relative to the workpiece; a jig moves the piece while the tool remains stationary. Purpose A fixture's primary purpose is to create a secure mounting point for a workpiece, allowing for support during operation and increased accuracy, precision, reliability, and interchangeability in the finished parts. It also serves to reduce working tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
