Laser drilling machine is a high-precision and high-efficiency processing equipment widely used in multiple industries. Laser drilling technology utilizes high-energy density laser beams to locally heat materials, achieving precise drilling. This article will provide a detailed introduction to laser drilling machines
The working principle of laser drilling machine
Laser drilling machines mainly generate high temperatures on the material surface by focusing the laser beam, causing the material to melt or evaporate, thereby achieving drilling. Compared with traditional mechanical drilling, laser drilling has higher accuracy and a smaller heat affected area. Laser drilling can adjust parameters such as laser power, pulse width, and frequency according to different needs to adapt to different materials and drilling requirements.
Technical characteristics of laser drilling machines
High precision and high repeatability: Laser drilling can achieve precision at the micrometer or even nanometer level, and has extremely high repeatability.
Non contact machining: Laser drilling is a non-contact machining method that does not generate mechanical stress and is suitable for brittle or hard materials.
Can process multiple materials: Laser drilling is suitable for various materials such as metal, non-metal, composite materials, etc.
Flexible and adaptable: Laser drilling machines can adapt to drilling needs of different shapes and sizes by adjusting laser parameters.
