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 incread 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

1 One of the advantages of high-speed machining
High—speed machining as a die—efficient manufacturing， high—quality, low power consumption in an advanced manufacturing technology. In conventional machining in a ries of problems has plagued by high-speed machining of the application have been resolved。

High—speed cutting of the spindle speed, feed rate compared withtraditional machining, in the nature of the leap， the metal removal rate incread 30 percent to 40 percent, cutting force reduced by 30 percent, the cutting tool life incread by 70％ 。 Hardened parts can be procesd, a fixture in many parts to be completed rough, mi—finishing a冰雪奇缘简笔画

surface quality requirements, thus increasing the processing productivity and competitiveness of products in the market.

High-speed machines generally have high rigidity and precision， and other characteristics, processing, cutting the depth of small, fast and feed， cutting force low， the workpiece to reduce heat distortion， and high precision machining, surface roughness small. Milling will be no high-speed processing and milling marks the surface so that the parts greatly enhance the quality of the surface。 Processing Aluminum when up Ra0。40.6um, pieces of steel processing at up to Ra0.2 ～ 0。4um。
1.3 Cutting reduce the heat
Becau the main axis milling machine high—speed rotation， cutting a shallow cutting, and feed very quickly， and the blade length of the workpiece contacts and contact time is very short, a decrea of blades and parts of the heat conduction。 High-speed cutting
by dry milling or oil cooked up absolute （mist） lubrication system， to avoid the traditional processing tool in contact with the workpiece and a lot of shortcomings to ensure that the tool is not high temperature under the conditions of work， extended tool life.
1.4 This is conducive to processing thin—walled parts
High-speed cutting of small cutting force, a higher degree of stability, Machinable with high-quality employees compared to the company may be very good, but other than the company’s employees may Suanbu Le outstanding work performance. For our China practice， we u the models to determine the method of staff training needs are simple and effective. This study models can be an external object， it can also be a combination of internal and external。 We must first clear strategy for the development of enterpris。 Through the internal and external business environment and organizational resources, such as analysis, the future development of a clear business goals and operational priorities。 According to the business development strategy can be compared
to find the business models， through a comparative analysis of the finalization of business models. In determining business models， a, is the understanding of its development strategy， or its market share and market growth rate,
