Relying on the progress of science and technology, various professions for the fine degree of machining technology requirements, appear to be more and more high, take the example of the present integrated circuit reference to the advancement of the integrated circuit, which is presented in a square millimetre in the plane of the number of integrated components, has reached hundreds of thousands of so many, and it requires the line width and positional errors, but also extremely small, even if it is subtle to the end of the distance error, it is extremely likely to Resulting in the production of products suffered, in this way, the fine degree of machine tool processing in the past, will not be able to meet such a high standard of processing expectations, and therefore, with the degree of ultra-precision machining technology revealed and developed, is also in line with the current industrial sector for the machinery processing industry technology to be upgraded to meet the demands of the industrial sector.
1 Principle of ultra-precision machining technology
The reason why the production of ultra-precision machinery material is very small, is because it requires extremely complex processing technology, its processing steps are numerous, the accuracy of its processing shape to reach hundreds of microns, or even hundreds of nanometres of precision, the surface roughness standard is also within the range of hundreds of nanometres, which can be seen in the machining process of the degree of difficulty. In addition, the machining process also requires cutting, grinding and other production processes, which also adds to the difficulty of the task of the machining process. If there is a situation in the processing process, resulting in mechanical precision deviation, even if the magnitude of the deviation is very small, but when the machinery is actually used in actual production, the products manufactured will not meet the requirements, which will bring about losses will be incalculable.
1.1 Ultra-precision machining ofCutting technology
In the ultra-precision machining technology, in order to ensure the precision of the processing machinery and the quality of machinery, the most critical production link is the cutting process, therefore, in the cutting process, it is required that the technicians put all their energy and infinite patience. In order to reduce the error generated in the cutting process, not only to control the temperature of the cutting environment, but also to control the cutting edge degree, followed by the cutting form, after many years of continuous experiments from countless scientists in the international community, the final confirmation of the data required to achieve the various factors in the cutting process, which effectively enhance the level of cutting processing technology.
1.2 Grinding technology for ultra-precision machining
It is ultra-precision machining in the grinding technology, is the product processing polishing and grinding where the link, but because of the nature of the processed material problems, resulting in a lot of material is very fragile, in those grinding processing link, more likely to appear in the situation of material fracture, which will cause a great deal of waste. Based on this, in the grinding process technology, the need to improve the rigidity of the processing machine, but also to protect the accuracy of the machine tool in the high-speed running process, and at the same time to ensure that grinding has a sharp edge, so as to effectively ensure the quality of the processed products, and thus improve the production efficiency of the product. 1.Ultra-precision machining, grinding technology exists in the product grinding process, but also have to do the grinding process of the product, but due to the shape of the product, resulting in product grinding failure. Product shape problems, resulting in a high failure rate of product grinding, product grinding failure means to repeat the product grinding process, which makes the product completion time is extended, the product production efficiency decline, so in the product grinding stage, the product must be for the product residence time and product feed speed as far as possible to make accurate estimates, so as to enhance the success rate of the product in this stage.
2 characteristics of ultra-precision machining technology
2.1 Characteristics of ultra-precision
The most important feature of ultra-compact machining technology is the ultra-precision requirements on the size and shape of the processed object, which is compared with the traditional precision machining technology.
2.2 Highly Intelligent Features
Compared with the traditional precision machining technology, where workers rely on their own experience and sense of touch to operate, ultra-compact machining technology has a higher level of highly intelligent automatic machining equipment, which effectively improves the stability of the machining process and ensures high efficiency of the machining process.
2.3 Characteristics of information technology
Because ultra-precision machining has ultra-precision and highly intelligent characteristics, and this characteristic is known by the above, so during the processing period, the need for a large number of input information, but also information control and information feedback, and in this process, must be combined with information processing technology, so as to effectively ensure that the processing process has a high degree of efficiency.
3 Ultra-precision machining technology in the future development of the
As technology continues to develop, machining technology must continue to be upgraded to meet the needs of science and technology. At present, countries in the aerospace field, nanotechnology field and information technology field and other high-end industrial development, need to be supported by ultra-precision machining technology, in order to effectively achieve further development. Simply from the precision of product processing, the industrial sector upgrading needs of mechanical precision is gradually increased, the level of processing technology requirements gradually from the micron level to the sub-micron level development. In recent years, along with the development of nanotechnology, nanotechnology applications in a wider and wider range of fields, such as medicine, artificial intelligence, etc., the requirements of machining precision is to reach the level of nanometre level. From this, we can boldly predict that the future of ultra-precision machining technology will be further developed to the atomic level. In the ultra-precision, high intelligence, information processing technology features, ultra-precision machining technology will be more and more refined, the entire ultra-precision machining system is becoming more and more perfect, and ultimately form a complete industrial system, the machining industry as a whole, the overall level of industry significantly improved, can be applied to a wider range of technical fields, and become a strong impetus for the further development of industry.
4 Conclusion
In summary, we can find that the ultra-precision machining technology has a very good development prospects, and its technical support for various high-end industrial fields, but also a huge development assistance, so it also has a high economic value. From the ultra-precision machining technology in the future development situation, it can be applied to the technical field will be more and more broad, so for the ultra-precision machining technology research, still to be scientists for further investigation.
