由于集成电路、特别是大规模集成电路的日益广泛应用,使电子设备向高可靠性、高精度、小型化和高密集迅速发展。印制板是必不可少的部件,提高印制板生产的精度、可靠性及生产效率就日益显得重要。因而,高速数控钻床就成了这种加工技术中极重要的生产设备。国际上,特别是美国、日本等国早在六十年代就大量生产数控钻床,现已普遍应用了计算机控制的高速钻床。在
Due to the increasingly widespread use of integrated circuits, especially large scale integrated circuits, the rapid development of electronic equipment to high reliability, high precision, miniaturization and high density. Printed board is an essential part, to improve the accuracy of printed circuit board production, reliability and production efficiency is increasingly important. As a result, high-speed CNC drilling has become such an important processing technology in the production equipment. Internationally, especially the United States, Japan and other countries as early as the 1960s on the mass production of CNC drilling machine, now widely used computer-controlled high-speed drilling machine. in
