Laser fine processing is an advanced technology that utilizes a laser beam with high brightness and directional properties to focus energy onto materials for processing. It has a wide range of applications, including precision cutting, precision welding, precision punching and surface treatment, and is widely used in the fields of cell phones, new energy batteries, PCBs and so on. Especially in the field of precision manufacturing, laser fine processing, with its high efficiency, high precision and low energy consumption, is considered one of the leading technologies in the future, which helps to promote the development of precision manufacturing in the direction of higher precision, higher efficiency and higher quality, and plays a very important role. 

For example, precision cutting can realize high-precision cutting, accuracy up to the micron level, cutting surface smooth and thermal deformation is small; precision welding can effectively improve the welding quality and welding strength, and realize high-efficiency welding; precision punching can realize extremely high-precision processing of small holes or fine holes for micro-nano manufacturing, optical components processing and other high-precision requirements of the field. In addition, laser fine processing also has the advantages of multi-functionality, adaptability, good processing quality, high processing accuracy, high processing efficiency, high economic efficiency, energy saving and material saving, no pollution and pollution. However, the high cost of equipment for laser fine processing and the strict skill requirements of operators are problems that need to be solved gradually.
