1. Differences in marking principles

The  co2 laser marking machine uses carbon dioxide gas discharge to generate a laser beam for marking or cutting on the surface of the material. 

The wavelength of the beam is 10.6μm, which is suitable for marking non-metallic materials. 

The optical fiber laser marking machine uses laser to transmit the beamto the surface of the workpiece through the optical fiber for marking or cutting. The wavelength of the beam is 1.06μm, which is suitable for marking metal 

materials.

2. Differences in applicable materials

Due to the wavelength of co2 laser, co2 laser marking machines are mainly suitable for non-metallic materials, such as rubber, plastics, ceramics, glass, etc.; while fiber laser  marking machines are suitable for harder materials, such as metals, alloys, steel, and copper. wait.

3. The difference between accuracy and speed

Because the wavelength of the beam is longer, the co2 laser marking machine can perform rough engraving, sketching, spraying and other operations. However, the accuracy is relatively low, and it meets the industrial marking requirements for most non-metallic materials.

Because the fiber laser marking machine has a shorter beam wavelength and a higher laser beam spot focusing power, its marking effect is more delicate and clearer, and it is more suitable for small processing parts. Its marking speed is faster, and it can also Meet the marking needs of complex graphics, large quantities, and high speed.

In conclusion:

In general, co2 laser marking machines and fiber optic laser marking machines have their own characteristics and are suitable for different materials and marking needs. When choosing a marking machine that suits you, you need to consider factors such as material, size, shape, accuracy, and speed.
