With high demand and rapid development of micro-machining technology in civil, industrial, medical, or aerospace fields, the development trends to request higher processing precision and higher finishing quality. 

Traditional machining, EDM and electron beam processing methods cannot meet the technical requirements of high-precision micro-hole machining such as the size and precision, the taper controllability of micro-holes, the ability to deal with a large aspect ratio hole and the wide applications on high hardness, high melting point, and high brittle materials. Laser processing has the advantages of high precision, high efficiency, low cost, low material selectivity, etc. It has become one of the top technologies for high precision micro-processing.

Generally, the holes processed by the scanning galvanometer are all positive tapers, and it is challenging to realize the processing of different taper holes and shaped holes cause the failure to control the touching angle. Widely used long-pulse laser processing has a large heat-affected zone which would get recast layers.

Han’s Laser did deep researches and now launch the "multi-axis ultra-fast micro-machining equipment" HN-GY-PS60, which can not only realize X, Y, Z motion control in three directions and also possible to rea-time control the rotation of the laser beam and the laser touching angle. We also provide assistance options such as coaxial observation camera, fume extractor, and real-time power monitoring system, etc., to help customers manage the process. The customer can realize the drilling and cutting of various holes such as cylindrical holes, positive tapered holes, negative tapered holes, and square holes by any combination of processing parameters.
