超精密切削加工技术是适应尖端技术的需要,而于60年代发展起来的一种机械制造新工艺,它综合了近代的先进技术和工艺,在20多年内,使机械加工精度提高了1～2个数量级,从50年代末的微米级提高到今天的几十毫微米级(即从微米提高到0.01微米)。美国Pneumo Precision公司研制的超精密金刚石切削加工机床,可加工最大外径为350mm,最大端面尺寸为560mm,采用空气轴承的主轴转速最高达 Ultra-precision machining technology is to adapt to the needs of cutting-edge technology, and developed in the 60’s a new mechanical manufacturing process, which combines the modern advanced technology and process in 20 years, the machining accuracy of 1 to 2 An order of magnitude from the micron level at the end of the 1950s to tens of nanometer levels today (ie from micron to 0.01 micron). The United States Pneumo Precision company developed ultra-precision diamond cutting machine, Machinable the largest diameter of 350mm, the largest end size of 560mm, the use of air bearing spindle speed up to
