Based on the material properties and structure of parts, the machining experiments of NC drilling and detecting process were developed. Through the experiments, the main factors were examined which influence machining quality and efficiency. The detection methods of multiple micro holes were investigated. Finally, an automatic programming was developed by use of Visual Basic6.0.The grid of tungsten foils were machined by use of thermo grip and NC drilling. Simultaneously, the burrs were wiped off by use of equipment of ultrasonic. The results showed that the process time of drilling was about 2 seconds and a single bit could drill more than one thousand holes. The quality and efficency all meet the requirement. The computered radiography is suitable for rapid and precise detection of the grid of tungsten foil.
