The Difference Between CO2 Laser Engraving Machine And CO2 Laser Marking Machine

Sep 21, 2019

1. The depth of processing and printing is different. Laser engraving machines generally have deeper engraving depths and greater power. Laser power ranges from 40W to 150W. The depth of engraving varies from 0.1mm to 80mm, and the depth of engraving depends on the specific material. In general, wood, sponge, propylene vinyl and other materials are deeply engraved. CO2 marking machines generally have a print depth of less than 5 mm and a power range from 40 W to 60 W.
2. Processing speed is different. The engraving machine speed of the laser engraving machine is generally 680mm/s. The engraving speed is 1200mm/s. The speed of the marking machine is 2500mm/s.
3. The accuracy and speed of the marking machine are much higher than that of the engraving machine. The CO2 marking machine's laser is a thin beam that acts on the surface of the material. The fine line width can be as high as 0.02mm, which is more suitable for precision machining.
4. The laser is different. The engraving machine is generally made of the glass tube and has a life of about 1000 hours. It needs to be equipped with a water cooler.
The marking machine is generally made of metal tube and has a service life of about 20,000 hours. It does not need to be equipped with a water cooler.
5. The working area is different. The engraving machine has a large working area. The laser engraving machine means that the main axis of the engraving machine is replaced by a laser focusing lens, and the processing tool is replaced by a laser. Therefore, as long as the ZYZ axis is long, the working width can be large. Therefore, the accuracy is relatively poor. The marking machine uses a galvanometer scan and the size of the field lens to determine the marking area. Generally between 110*110-300*300mm.
6. The difference between the application materials. The materials used for the engraving machine are relatively wide. For example crystal, acrylic, wood, marble, cloth, leather, felt, paper, PVC, plastic, etc. Laser marking machines are mainly used for glass, leather, plastics, etc.
