Laser drilling utilizes a high-energy laser beam to ablate or melt quartz tube material, thereby creating holes. The high energy density and precise focusing of the laser beam enable a rapid and accurate drilling process, while also preventing material damage and deformation often associated with traditional mechanical drilling.”
High Precision
Laser drilling enables high-precision hole creation, ensuring the accuracy of quartz tube machining and the quality of the final product. Achievable hole diameters can be as small as 1 micrometer, meeting the requirements of micro-fabrication.
High Efficiency
Laser drilling is a highly efficient machining method, capable of completing large-volume drilling tasks in a short time, thereby increasing production efficiency. The perforation speed is 10 to 1000 times faster than traditional mechanical equipment.
Non-Contact Process
Laser drilling is a non-contact machining method that avoids any damage or contamination to the surface of the quartz tube, ensuring the integrity of the final product.
Excellent Controllability
Laser drilling technology allows for the creation of holes of various shapes and sizes based on the actual requirements. Through adjusting laser power and processing parameters, precise control over hole size and shape can be achieved.
Equipment Selection
When choosing laser drilling equipment, select appropriate models and configurations based on processing needs and budget. Furthermore, consider the brand and quality of the equipment to ensure its stability and reliability.
Process Parameter Adjustment
During processing, adjust parameters based on the material, thickness, and processing requirements of the quartz tube to achieve optimal results.
Safety Precautions
Laser drilling generates intense laser radiation and high temperatures. Therefore, safety precautions such as wearing protective eyewear and clothing must be followed.
Maintenance and Upkeep
Regularly maintain the laser drilling equipment, including cleaning the lens, checking the cooling system, and replacing worn parts, to ensure normal operation and extend the equipment’s lifespan.”

Frequently asked questions
Quartz glass is a hard and brittle material with excellent physical and chemical properties, extremely high mechanical hardness, good electrical insulation, high temperature and corrosion resistance, low and stable delay performance, good light transmittance, etc. It is widely used in semiconductors, optics, electricity, chemistry, aerospace, automobiles and other fields. Hard and brittle materials are difficult to process, and many fields urgently need cutting processes with small edge collapse, less material loss, low cross-section roughness, and a wide cutting thickness range. The traditional cutting method of quartz glass is mechanical cutting, that is, wheel cutting. Non-traditional cutting methods include water jet cutting, electrochemical discharge wire cutting, continuous laser cutting, etc. Mechanical cutting has low cost, but the contact between the wheel and the material causes large tool wear, and the material is easily contaminated by the tool. Quartz glass is prone to edge collapse, microcracks, and residual stress, which affects the strength and performance of the material! It is difficult to achieve curve cutting and requires post-processing, such as grinding and polishing. Laser cutting does not directly contact the material, has no contact stress, and can perform complex curve cutting. Picosecond laser has the advantages of small spot diameter, high precision, short action time with the material, and small action area, and is suitable for the processing of hard and brittle materials.
