my country made breakthroughs in the core technology of ultra-precision machining
Not long ago, the administrator saw a report on Ultra Precision Machining on the website, saying that with the efforts of many experts, our country has made a very big breakthrough in the field of Ultra Precision Machining technology. my country has made breakthroughs in the core technology of Ultra Precision Machining, which controls fine movements of 1/10,000th of a millimeter. Recently, this 11th Five-Year Plan project with my country's independent intellectual property rights-supporting technology for automotive crankshaft and camshaft follow-up grinding equipment has passed the national level appraisal. This is of great significance for improving the overall level of my country's machinery manufacturing industry. This technology is an experiment carried out in a production workshop in Zhejiang. The crankshaft follow-up grinder manufactured by Precision Machining Technology and the same type of foreign advanced grinder simultaneously process the same type of crankshaft. Appraisal experts separately extracted the workpieces to be processed on the spot, and conducted comparative testing with internationally recognized authoritative testing equipment. The results show that the key index of the machine tool's machining parts-the roundness error of the connecting rod neck is only 0.0028mm, which is not only significantly better than the error value of 0.0042mm of the comparative machining parts, but also exceeds the accuracy of 0.003mm of foreign advanced similar grinding machines. standard requirement. This is a very proud result, which makes China's Precision machining industry raise its eyebrows. Some ultra-precision machining experts said that at present, only a few countries in the world control the core technology of related ultra-precision machining. Our country bought back Equipment from abroad, and then imitated it at first, and then surpassed it later. This can be regarded as one or two original breakthroughs. Mastering this core technology of ultra-precision machining pushes the development of Precision Machining and enhances its manufacturing. The overall level of industry has great practical significance. The person in charge of the company that produced the equipment said that the machine tool has the characteristics of high precision, long life, low cost, and the price is less than half of similar imported machine tools. The cost performance is very high, and it can be widely used to upgrade traditional grinding machines. The reporter learned from the interview that the research was included in the national high-tech research and development plan by the Ministry of Science and Technology in 2008, and was successfully overcome by a group of professors from Zhejiang Normal University. The technical achievements can be widely used in the processing and manufacturing of various mechanical power and transmission systems. With our country Chang'e 3 landing softly on the moon, our China became the third country in the world to successfully land on the moon, which indicates that our country can now walk in front of other countries in many aspects.
