CO2 laser cutting machine is a CNC laser machine that uses laser technology to cut and engrave materials. Since CO2 laser cutting machines can also engrave, CO2 laser cutting machines are also called CO2 laser engraving machines. In addition, some people also call it wood laser cutting machine or acrylic laser cutting machine, etc. 

Advantages, disadvantages and applications of CO2 laser cutting machine (Figure 1)

CO2 laser cutting machine uses a focusing lens to focus the CO2 laser beam onto the surface of the material to melt it. At the same time, coaxial compressed gas blows away the molten material. The laser beam moves along a certain path and forms a slit of a certain shape. Then the cutting process is completed.
              

Advantages of CO2 laser cutting machine

1. Fast cutting speed

2. High cutting efficiency

3. Small heat affected zone

4. Narrow incision

5. Suitable for cutting non-metallic materials

6. Not affected by the shape of the workpiece

7. Save materials and effort

Disadvantages of CO2 laser cutting machines

1. Low photoelectric conversion rate

2. High energy consumption

3. High operating costs

4. Includes a variety of consumables that require frequent maintenance.

Cutting materials and applications of CO2 laser cutting machines

The 40WCO2 wood laser cutting machine can mark steel, and the 90WCO2 laser engraving machine can directly engrave on the steel surface. Using oxygen as auxiliary gas, CO2 CNC laser cutting machines of 150W and above can cut 1mm thick steel plates.

Generally speaking, although CO2 laser cutting machines can process mild steel, aluminum, titanium and other alloys, their cutting efficiency is low. However, it is very good at cutting and engraving non-metallic materials. Materials that CO2 laser engraving machines can cut and engrave include:

  Non-metal: wood, acrylic, paper, cloth, epoxy resin, plastic, rubber, crystal, etc. CO2 laser cutting machines are widely used in clothing, leather, cloth toys, computer embroidery and cutting, electronic appliances, models, handicrafts, advertising and other industries Application and decoration, packaging and printing, paper products and other industries.
