What are laser engraving and laser cutting?
Laser: When the electrons in the atom absorb energy and jump from a low energy level to a high energy level, and then fall back from a high energy level to a low energy level, the released energy is released in the form of photons.
Laser engraving: It uses high-density laser beams to irradiate materials, and generate high temperature on the surface of the material during the engraving process and gasify to achieve an engraving effect that is different from the surface of the raw material.
Laser cutting: It uses a high-power, high-density laser beam to irradiate the material, to generate high temperature that makes the material quickly gasify to form holes, and blows off the molten material with the help of high-speed airflow. As the beam moves, the continuous holes form a narrow slit to complete the cutting of the material.
Features of laser engraving/cutting: With non-contact processing, it is not affected by the elasticity and flexibility of materials, convenient for processing soft materials, and will not cause mechanical extrusion or mechanical stress to materials. On the other hand, it has high precision, fast speed and wide application fields.
There are many factors that affect the engraving effect, including focal length, power, speed, fast axis and slow axis scanning direction, line interval, air assist, software algorithm, machine assembly differences, different materials, etc.; similarly, focal length, power, speed, fast axis and slow axis cutting path, air assist, honeycomb panels, machine assembly differences, and different materials and cutting time will also affect the cutting effect.
