激光钻削是发展钻削加工的最有效技术之一。这种加工工具能有效地钻削孔径小达5μm的小孔。此外,激光钻削通常没有切屑和毛刺。激光钻削主要应用于飞机发动机中高温合金的冷却孔、内高速齿轮的润滑孔、排气孔以及电子基片中的小孔等加工。一、优点激光钻削具有许多独特的优点: 1.刀具与工件问不直接接触,排除了诸如材料变形、刀具破损、刀具磨损以及过热一类的问题。2.由于激光器是光学瞄准,能够钻出极其精密的孔。直径精度一般在±0.025mm以内。
Laser drilling is one of the most effective techniques for developing drilling. This machining tool effectively drills small holes up to 5μm in diameter. In addition, laser drilling is usually free of chips and burrs. Laser drilling is mainly used in aircraft engine cooling alloy high-temperature alloy hole, high-speed gear lubrication holes, exhaust holes and holes in the electronic substrate processing. First, the advantages Laser drilling has many unique advantages: 1. Tool and the workpiece does not ask direct contact, ruled out such as material deformation, tool damage, tool wear and overheating of a class of problems. 2. Because the laser is optically aimed, it can drill extremely precise holes. Diameter accuracy is generally within ± 0.025mm.
