Since the end of the 20th century, and ultra-processing technology was introduced, and its gradual application to machining technology. Many of these technologies first applied in the process of modern weapons production, followed by these technologies has been a huge development and attention to the direction of the development of the machinery processing industry has a qualitative impact. Super machining technology improves the performance and quality of mechanical products, has become the core technology in the competition of mechanical manufacturing technology. , ultra-processing is the development of machining technology higher. At present,, ultra machining technology has made a lot of achievements, such as super cutting technology, metal bond grinding wheel dressing wheel mirror grinding technology and grinding and polishing processing technology. In the current application, diamond turning tool super cutting, diamond micro powder grinding wheel super grinding and super abrasive belt grinding and research and polishing in machining technology is more significant. In addition, ultra-processing technology for product quality, human error, the application of automation technology to assist. Since entering the 21st century, China's machining technology in the product, ultra aspects have made great progress, mainly reflected in the processing accuracy has been gradually to quantization, miniaturization processing direction. The relevant institutions found that, the development of ultra-processing technology is mainly towards two directions: one is to the amount of ion beams; the second is to three-dimensional surface processing-based detection technology. Our country in the study of technology on the basis of ultra-processing technology research is mainly focused on the basic principles, processing technology and processing accuracy and so on.
