近年来,与电子技术有关的计算机、通讯机器等都在开发高性能、高质量的产品。电子机械的主要部分电子线路是由印刷电路板组成的。过去,印刷线路板主要用于附加价值很高的仪器;最近,多用于家庭电器等产品上。这种趋向,要求印刷线路板的部件装配、配线应实现高密度化,并进行大批量生产和降低成本。线路板制造工序之一就是钻孔,现在,可在一块线路板上钻几千个到几万个孔。钻孔加工主要是在NC钻床上进行,刀具是用微小直
In recent years, computers and communication machines related to electronic technology are developing high-performance and high-quality products. The main part of electronic machinery is composed of printed circuit board electronic circuit. In the past, printed circuit boards were mainly used for high added value of the instrument; recently, used for household appliances and other products. This trend requires the assembly of printed circuit board components, wiring should be high density, and high-volume production and reduce costs. One of the circuit board manufacturing processes is drilling, and now, thousands to tens of thousands of holes can be drilled on a circuit board. Drilling is mainly carried out on the NC drilling machine, the tool is a slight straight
