现代飞行器的发展,对机载设备提出了越来越高的要求。要求高精度、长寿命、高可靠性、综合化和小型化。常规的加工方法已无法满足机载设备的制造要求。必须大量采用新工艺,特别是高精工艺和特种工艺,精密、超精密加工技术是其中最为有效的加工手段之一,也是近十多年来,国外发展最快的技术领域之一。国外新一代机载设备产品对机
The development of modern aircraft, airborne equipment put forward higher and higher requirements. Requires high-precision, long life, high reliability, integration and miniaturization. Conventional processing methods have been unable to meet the manufacturing requirements of airborne equipment. It is necessary to adopt a large number of new processes, especially high-precision and special processes. Precision and ultra-precision machining technologies are among the most effective processing methods and one of the fastest growing foreign technology fields in recent 10 years. A new generation of foreign airborne equipment products to the machine
