As the manufacturing industry continues to grow demand for high-precision and high-efficiency processing technology, the market potential of water-guided laser processing technology is gradually emerging. In high-end manufacturing fields such as aerospace, electronics manufacturing, medical equipment and automobile industries, the processing quality and accuracy of materials are extremely high. Traditional processing methods are difficult to meet these needs. However, water-guided laser processing technology has become an ideal solution to these problems due to its unique advantages. Traditional laser processing still has some limitations, such as large heat-affected zones and poor processing effects on highly reflective materials and heat-sensitive materials. In order to overcome these problems, researchers tried to introduce high-speed water jets into the laser processing process, forming water-guided laser technology. This technology uses water jet as the guiding medium and cooling medium for the laser beam, improving processing quality and material adaptability. Water-guided laser processing technology has been widely used in the manufacturing industry through the improvement and innovation of traditional laser processing and water-jet cutting technology, due to its high energy density and high precision.
