Advantages of 20w laser marking machine

1. Text or image marking without distortion, high precision, repositioning accuracy is 0.001mm.

2. Non-contact processing, no damage to products, no tool wear, good marking quality.

3. The working speed is fast, which is 2-3 times that of the traditional one. The beam quality is good, the light spot is small, and the marking line width is extremely narrow, which can meet different marking needs.

4. Integrated design with laser shield, safe to use.

5. The red light positioning system is adopted, which is convenient for positioning and has high positioning accuracy.

Exhaust and dust removal system

20w laser marking machine dust extraction system-Suntop
