“…It's a hot issue in processing areas. It's the most difficult processing of drilling the high quality micro-hole in all means of cutting and milling, etc.. At present, the way of micro-hole [1] processing are mechanical drilling, EDM drilling, a long pulse laser drilling, femtosecond laser drilling, etc.. With the miniaturization of core components in processing areas, the holes also become massive, small, high-precision and high-quality. With the processing requirements getting higher and higher in micro hole drilling, the traditional means of processing are difficult to overcome technological bottlenecks.…”

Based on the femtosecond laser processing technology and PZT driving scanning technology,high-precision micro- manufacturing technology is developed. By adjusting the laser parameters and scanning parameters to get micro-hole machining on the flat or curved surface. Hole’s size and surface morphology is observed by using phase contrast microscopy and scanning electron microscopy observations, and the surface roughness is analyzed by the surface profile instrument. The feasibility of diesel injector nozzle processing is verified in practical industry applications. The results show that this method of making micro hole has significant advantages, such as high precision, good consistency, without burrs, good surface roughness and high efficiency. These characteristics can meet the practical application requirements and can be used in various industrial fields.
