高速铣削----——[外文翻译].doc

High-speed machining is an advanced manufacturing technology, different from the traditional processing methods. The spindle speed, cutting feed rate, cutting a small amount of units within the time of removal of material has increased three to six times. With high efficiency, high precision and high quality surface as the basic characteristics of the automobile industry, aerospace, mold manufacturing and instrumentation industry, such as access to a wide range of applications, has made significant economic benefits, is the contemporary importance of advanced manufacturing technology. For a long time, people die on the processing has been using a grinding or milling EDM (EDM) processing, grinding, polishing methods. Although the high hardness of the EDM machine parts, but the lower the productivity of its application is limited.


高速切削加工是一种先进制造技术，不同于传统加工方式。它的主轴转速高、切削进给速度高、切削量小，单位时间内的材料切除量却增加3～6 倍。它以高效率、高精度和高表面质量为基本特征，在汽车工业、航空航天、模具制造和仪器仪表等行业中获得了广泛的应用，取得了重大的经济效益，是当代先进制造技术的重要应用。长期以来，人们对模具的加工一直采用铣削一磨削或者电火花(EDM)加工、打磨、抛光的方法。虽然电火花可加工硬度很高的工件，但较低的生产率使它的应用受到制。随着高速加工技术的发展，采用高速切削取代磨削抛光和电加工进行模具加工已成为可能。
