超精密加工技术,或称微英寸加工技术,除应用于惯性仪表、激光核聚变用的金属反射镜、天体望远镜的金属镜制造外,随着电子技术、激光技术和计算机技术的发展,已成为开发磁盘、CD(光盘)、VTR(录相头)、激光打印机、光学医疗设备等技术密集型新产品的关键性技术。因此,开发超精密加工技术是各国制造技术发展的重点。 Ultra-precision machining technology, or micro-inch processing technology, with the exception of the metal mirror used in inertial instruments, laser fusion and celestial telescope manufacturing, with the development of electronic technology, laser technology and computer technology has become Develop key technologies for technology-intensive new products such as magnetic disks, CDs, VTRs, laser printers, and optical medical devices. Therefore, the development of ultra-precision machining technology is the focus of development of manufacturing technology in various countries.
