翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Hypertherm ： ウィキペディア英語版 Hypertherm Hypertherm is an American corporation which designs and manufactures advanced cutting systems such as plasma cutting machinery and related high-technology industrial applications for specific use in a wide variety of industries such as shipbuilding, manufacturing, and automotive repair. It also develops and produces man-portable handheld and mechanized plasma cutters, fiber lasers, and waterjet cutting systems, along with consumables, CNC (Computer Numerical Control) motion and height controls, and nesting and process optimization software. The company employs around 1,400 people: approximately 1,100 people at its main headquarters in New Hampshire, and another 300 throughout its international offices in Europe, Asia, and Latin America. ==History of Hypertherm and plasma cutting== Plasma cutting was accidentally discovered in the 1950s by scientists working for the U.S. defense industry. The scientists learned that increasing the gas flow and reducing the opening in the gas nozzle used in TIG welding would result in the formation of a plasma jet. However the technique wasn’t widely used because a phenomenon called double arcing (in which one arc forms between the plasma electrode and nozzle and a second arc forms between the electrode and nozzle), damaging both the electrode and cutting nozzle. Eight years later, in an attempt to control double arcing, a dual flow technique was introduced. The technique involved adding a second gas shield around the plasma nozzle. Although lessened, double arcing was still a problem. It wasn't until 1968, when Dick Couch, who went on to found Hypertherm, invented Water Injection Cutting, a process that involved radially injecting water into the nozzle. The end result was a faster and better cut, as well as less dross and the virtual elimination of double arcing. It is this invention, that made plasma cutting a viable option for companies needing to cut metal. The initial discovery of Water Injection Cutting was followed four years later by Hypertherm's introduction of a water muffler and water table that lessened the noise, smoke, and light that traditionally occurred during the cutting process. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hypertherm」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
