1. Automatically adjust the✘♠  focal length: automatic focus∞∑ing and marking can be$ ® achieved through the auto‍<"matic focusing syste₹&$ m, even if the thickness oα®f the workpiece has slight $≤φ→differences

2. The structure is simp∞£↕le, only need to ins'∑ ​tall an automatic focus✘ε ing system on the original laser♠&∑ equipment;

3. Higher marking accuracy;

4. Low cost: It reduces the waste of m£×anpower and material re™π£sources and improves the effi ε≠αciency of marking. Improve→♠γ< quality and save ti' me for customers, thereby savingα>★ costs for customers.
