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.”
よくある質問
石英ガラスは硬くて脆い材料で、物理的、化学的性質が優れ、機械的硬度が非常に高く、電気絶縁性がよく、高温と耐食性に優れ、遅延性能が低く安定で、光透過性がよい。半導体、光学、電気、化学、航空宇宙、自動車などの分野で広く使用されている。硬くて脆い材料は加工が難しく、多くの分野で刃先の倒れが小さく、材料ロスが少なく、断面粗さが小さく、切断厚さ範囲が広い切断加工が急務となっている。石英ガラスの伝統的な切断方法は機械的切断、すなわち砥石切断である。非伝統的な切断方法には、ウォータージェット切断、電気化学放電ワイヤー切断、連続レーザー切断などがある。機械的切断はコストが低いが、ホイールと材料が接触するため工具の摩耗が大きく、材料が工具によって汚染されやすい。石英ガラスはエッジ崩壊、マイクロクラック、残留応力が発生しやすく、材料の強度や性能に影響する!曲線切断が難しく、研削や研磨などの後処理が必要。レーザー切断は材料に直接触れないため、接触応力がなく、複雑な曲線切断が可能です。ピコ秒レーザーは、スポット径が小さい、精度が高い、材料との作用時間が短い、作用面積が小さいなどの利点があり、硬くて脆い材料の加工に適しています。
