It is mainly used for processing micro-holes with small diameter, high depth and complex shape on the surface or inside of various materials. These micro-holes often serve as functional components for airflow control, liquid channel or signal transmission, so the processing quality and precision of micro-holes are crucial to the performance of the overall system. With the increasing demand for micro-processing in the industry, higher precision, efficiency and adaptability are required for micro-hole manufacturing equipment.

[0003] Compared with traditional mechanical processing or electric spark processing equipment, the micro-hole manufacturing equipment based on ultra-short pulse laser has unique advantages. Ultra-short pulse laser has concentrated energy and extremely short single pulse action time, which can realize cold processing without thermal influence zone, and is suitable for high-precision and high-demand material micro-hole processing. At the same time, ultra-short pulse laser has good adaptability to hard and brittle materials, composite materials and other difficult-to-machine materials, and is not prone to defects such as cracks and deformation during processing.
