Recently, I have received a lot of inquiries from readers about laser cutting. Maybe many people don’t know much about laser cutting machines. For this reason, I have sorted out an article about the types of laser cutting machines here, hoping to help you who are confused.
The principle of the laser cutting machine is to focus the laser emitted from the laser into a high power density laser beam.
When the laser beam is irradiated on the surface of the workpiece, the workpiece will reach the melting point or boiling point.
At the same time, the high-pressure gas coaxial with the beam will blow away the molten or vaporized metal.
With the relative position of the beam and the workpiece moving, the material will eventually form a slit, thus achieving the purpose of cutting.
What are the types of laser cutting machines?
