Manufacturing technology of the main basis for nc machining technology, with the development of manufacturing technology, also has made great progress in the end of the 20th century, entered the high speed cutting with development, the development of new cutting technology and the processing method, providing a complete set of technology for the development of the characteristics of the new stage.It is important in manufacturing industry, such as the automotive industry, aerospace industry, energy industry, military industry and new mould industry, electronic industry departments such as the main processing technology, is also the industrial sector of the rapid development of the important factors.Therefore, in the manufacturing industry developed countries such as America, Germany, Japan maintained a rapid development momentum.Metal cutting tool as a supportive technology and equipment, numerical control machine tool is indispensable in the numerical control processing technology, entered the development stage of "nc tool", show the "3 tall one only" (that is, high efficiency, high precision, high reliability and specialty).
Obviously, at the beginning of the 21st century, although near net shape technology, bulk forming technology is very promising new technology, but the machining as main foundation technology of manufacturing technology status will not change.Can see from the development trend of current manufacturing and manufacturing development and progress of human society to machining the dual challenge, this is also the main trends in the early 21st century machining technology.
High speed cutting will become a new technology
Current represented by high-speed cutting dry cutting, hard cutting and so on the new cutting process has shown a lot of advantages and strong vitality, become a manufacturing technology to improve processing efficiency and quality, the main way to reduce costs.
Therefore, the new cutting such as the development of high speed cutting technology promote the development of manufacturing technology is a new task faced by the modern cutting technology.Modern high speed cutting is not a small amount of cutting speed, is the need for overall progress in manufacturing technology and innovation on the basis of further, including numerical control machine tool, cutting tool, cutting tool material, coating structure technology, great progress of to reach the cutting speed and feed rate doubled, to make the whole machining manufacturing efficiency significantly.High speed cutting of the current level of practical application, make the whole machining 1 ~ 2 times higher cutting efficiency, narrow the gap with developed countries, is our country engaged in machining and cutting tools technology professionals in efforts to target and major challenge facing the new century.
Hard cutting is an application field of high speed cutting technology, which USES single blade or multitool machining hardened parts, it is better than the traditional high grinding efficiency, flexible, and the advantages of simple process, less investment, good effect has been applied to some fields.In the auto industry, with 20 crmo5 CBN cutting tool machining hardened gear (60 HRC) inner hole, instead of grinding, the surface roughness of 0.22 mu m, has become the auto industry to promote the new technology at home and abroad.
Innovative processing technology
For a long time, difficult to machining materials such as austenitic stainless steel, high manganese steel, hardened steel, composite materials, wear resistant cast iron is one of the most difficult problems in machining, such as the low cutting efficiency and tool life short.With the development of manufacturing industry, the amount of these materials in the 21st century will increase rapidly, processing of contradictions will become more prominent.At the same time, the product material will be constantly optimized, new engineering materials are available, and each kind of new material used for machining new requirements are put forward.As in the auto industry of machining more concentrated, the engine, transmission parts of silicon aluminium alloy continues to increase, the proportion of and began the introduction of magnesium alloy and high strength cast iron, new in order to reduce automobile weight and save energy consumption.And as in the aerospace industry, titanium alloy, nickel base alloy and super heat resistant alloy, ceramics and other hard processing material application proportion and processing difficulty also will further increase.Can efficiently processing these materials, is directly related to the automotive, aerospace, energy, and other important industrial sector development speed and overall level of manufacturing industry, is one of the biggest challenges for cutting technology.We must explore from now on, in order to fundamentally solve the difficult processing materials brought about by the extensive use of varieties properties and its century-old puzzle, innovative processing technology, development of new "blade", including laser, and the processing method.
To meet the requirements of manufacturing
After entering the 21st century, the trend of product diversification and individuation, manufacturing product updates will greatly accelerate the speed.Each kind of new product development means that significant changes of the parts function, structure, materials, and put forward development of machining tasks, like familiar, such as screw pump, patterned constant speed universal joint, the bottom diameter of the centering spline, electronic industrial products such as printed circuit board, which reflects the results of cutting technology and cutter.In the future as the speed of product updates faster, will form the machining new challenges.Not only that, the current use of machining flexible and modern machining and cutting tool technology, innovation parts processing methods, showing the characteristics of low cost, large output, fast effect.As in the 1990 s, the new focus on car engines, transmission line showed: cylinder hole is solid carbide diamond drilling technology, cylinder head cylinder of high speed milling technology, synchronizer gear broaching process such as the new processing technology, the production of new production line takt time shorten, improve product quality, a substantial reduction in investment, fully shows the great potential of machining.In this context, the manufacturing of machining, the demand for the new technology, new products will now reached an all-time high, which is both a challenge to cutting technology, is also a challenge to China's old cutting industry system.
