Development of Ultraprecision Machining Technology
Yi Weikun (Factory No.230 of Ministry of Aero-Space Industry)
Ever since sixties of this century, the new technology has been developed rapidly. High-precision manufacturing technology is required in a lot of new technology's products. This ultra precision machining has been developed into an independent technology system. Ultra precision machining technology consists of two aspects, ultra precision cut and micro-machining. They involve many major fields of modern science, and it is a technology with state-of-the-art significance. Its basic feature is micro cut suggested by America in early sixties. Now, academia and industrial circles of all countries in the world pay great attention to it and put a lot of funds, manpoweres, into a series of researches on this respect, and have achieved great successes. Factory No.230 has achieved some successes since the factory makes researches on ultra precision machining in seventies. They will build the most advanced technology system of ultra precision machining by pre-research and technology transformation in their country.
