Laser marking machine in the process of product processing, and sometimes there will be a spark to smoking in product marking surface, this phenomenon indicates that the product has been on the product surface marking effect is too large, the product has caused excessive power marking , and product marking effect either rough or has damaged the surface, the effects of laser marking requirements are relatively high, if you want to ensure the perfect effect of the product, the user must be familiar with the marking machine power regulation, and physical materials for different surface laser absorption proficiency! Eliminate the phenomenon of spark, then laser marking machine sparking what is it? One laser marking machine types: thermal processing type 1, generally the most commonly used laser is thermal laser processing, works by marking thermal energy or chemical products is a physical effect, thus completing the laser marking identification purposes . 2, the product material different properties, different substances to determine the absorption of the laser light is also very different. 3, there is a laser spot mode sparkle phenomenon also has some connection. 4. Focus adjustment: positive focus, defocus (defocus are divided into positive and negative defocus) the marking fruit have different effects. 5, marking speed and power can make some adjustments, using marking effect was more perfect. 6. Hardware: when galvanometer and laser marking delay correction is good, sparks node or break point should be able to mitigate. Laser marking machine summary: Laser marking machine Marking Products sparks although not completely avoided, but during the operation must first follow when marking proofing good focus adjusted, the optical power to the lowest in more slowly play a few samples, and slowly adjust the laser marking machine power until satisfactory so far. Also marking the course of these different materials have more contact proofing, also the subject of the rally very useful experience effects. Not only can improve the marking effect, but also reduce proofing sample loss.
