Benefits of Carbide Cutting Tools www.tool-tool.com
Bewise Inc. www.tool-tool.com Reference source from the internet.
In every machining system, one simply can't ignore the important role that cutting tools play. Oftentimes, the quality of a finished product would rely on the quality of the cutting tools. The quality and the performance of cutting tools would also directly affect a machining system's overall productivity. It is because of their importance that manufacturers would take into consideration several criteria before eventually buying a piece of cutting tool for their machining system. Included in these criteria are the tools ability to last long under rigorous operating conditions and their capability to perform at very high speeds. Also important is the tool's resistance to wear and tear, including resistance to breakage, edge and flank wear, cratering or top wear, chipping, built-up edge (BUE), deformation, and thermal cracking.
1. Kinds Of Tools
As the demand for better cutting tools increase, cutting tool suppliers also continuously develop products that can pass manufacturers' demands. Through the years, a lot of materials for the manufacture of cutting tools have been experimented upon; some have passed the standards while others were simply dropped. Today, there are only two types of cutting tools heavily favored in the machining industry: high speed steel (HSS) cutting tools and carbide cutting tools; and it seems that carbide cutting tools have slightly overtaken the other in popularity. So, what advantages do carbide cutting tools have over their HSS counterparts? Considering their lead in popularity, it is clear that the benefits of carbide cutting tools outnumber that of HSS cutting tools. And we'll understand these benefits better if we know what carbide really is.

CAD/CAM Considerations For Micromilling www.tool-tool.com
Bewise Inc. www.tool-tool.com Reference source from the internet.
The challenges involved in designing machine tools, cutting tools and fixtures to effectively mill features on miniature molds and microcomponents are daunting. The same could be said for optimizing tool paths for a tool that a machine operator probably won’t be able to see or hear while it’s in cut. Unlike standard milling operations, there’s no way that a machine operator can tell just how a tool is behaving while cutting in order to make the necessary changes to optimize the process. In addition, the toolpath strategies that might be suitable for “typical” milling work do not always scale down elegantly to work for micromilling applications.
probe
Still, there is an increasing demand for small part machining of medical, electronics and optic components. Recognizing this trend, the Fraunhofer Institute for Production Technology (IPT) in Aachen, Germany, recently sponsored a micromilling research project that brought together machine tool equipment manufacturers and mold makers with the goal of developing effective micromoldmaking strategies and processes. The struggle in creating NC software for micromilling has been effectively calculating tool motions with a tolerance of 0.1 micron. Cimatron (Novi, Michigan) is one software company that took part in the IPT project. The result was upgrading Cimatron E NC software to include a variety of functions for micromilling work.

La compañía española Gamesa participa en el programa 747LCF
Bewise Inc. www.tool-tool.com Reference source from the internet.
La compañía española Gamesa participa en el programa 747LCF con Boeing en todo el análisis de ingeniería y desarrollo de la “swing zone”. Esta sección es una estructura muy compleja por la cual el fuselaje trasero se abre para permitir la carga y descarga de las estructuras de materiales compuestos más grandes del 787, como las alas o el fuselaje.
Boeing ha anunciado hoy que ha seleccionado a Evergreen International Airlines para operar la flota de aviones 747 “Large Cargo Freigter” (LFC - Carguero de Gran Capacidad), compuesta por aviones 747-400 especialmente modificados para el transporte de grandes estructuras de los nuevos Boeing 787 Dreamliner.
Evergreen International Airlines (EIA), una filial de Evergreen International Aviation, operará rutas entre Estados Unidos y Japón. Evergreen ha seleccionado a Cargolux como empresa subcontratada para operar las rutas desde Europa. Además, Evergreen ha elegido a la americana Sojitz Corp. para coordinar la logística y otros servicios para las rutas japonesas.

Premier vol du 747 LCF www.tool-tool.com

Premier vol du 747 LCF
medium_lcf.2.JPG
Le premier 747 Large Cargo Freighter a effectué son premier vol le 9 septembre, donnant par la même le coup d’envoi à un programme d’essais en vol de 250h qui devrait se dérouler pour l’essentiel à Seatle. Ce premier vol de 2h04 a permis d’évaluer ses qualités de vol, de vérifier les niveaux vibratoires et de s’assurer de l’absence de flutter. 500h d’essais au sol sont également prévus. Premier d’une série de trois avions, le 747 LCF est destiné à transporter les sous-ensembles du futur Boeing 787 jusqu’à l’usine d’assemblage final situé à Everett (Washington, Etats-Unis) à partir de leurs sites de production répartis entre les sites de Wichita (Kansas, Etats-Unis), Charleston (Caroline du sud, Etats-Unis), Nagoya (Japon) et Grottaglie (Italie). Ce nouvel avion a fait sa première apparition non officielle à la mi-août. Il a été conçu à partir d’un 747-400 classique par les équipes de Boeing situées en Russie et aux Etats-Unis, renforcées par celles de sous-traitants situés en Espagne et en Hollande. Seule la transformation par Evergreen Aviation Technologies Corp (Taipei, Taiwan) de trois 747-400 en 747 LCF a été commandée à ce jour. Les deux premiers exemplaires devraient entrer en service début 2007.

制造高精密电镀CBN砂轮的新方法www.tool-tool.com
制造高精密电镀CBN砂轮的新方法www.tool-tool.com 碧威股份有限公司
www.tool-tool.com
轉述：
点击此处：以获得带文本搜索器的该文页面
图1 砂轮的分体结构
单 层电镀CBN砂轮磨削性能优越，适于成形和高速磨削。但砂轮不宜进行直接修整，砂轮制造精度成为影响最后加工精度的重要因素。外镀砂轮制造工艺简单、成 本低，但外露切刃参差不齐，初始磨削型面精度难以提高，且砂轮耐用度低，磨料损失严重，这是目前国内外电镀CBN砂轮使用中普遍存在的问题。
一、砂轮的分体结构
图1所示砂轮共分为四个部分：带锥孔的砂轮支承体；弹性薄壁套；与薄壁套相结合的无磨粒电镀金属层；以及带有磨粒的电镀金属层。锥孔设计是为了达到与砂轮轴装配时的同轴要求。
二、电镀过程
电镀工艺过程主要分为基体及磨粒准备、镀液调制、植砂和电镀(预镀、加厚镀)等，以及用于磨粒等高性改善的中期处理和相关镀后处理工艺。镀液是以瓦特镍为本液加含钴离子的溶液配制而成，如表1所示。
