What is the underlying reason behind the typical malfunctions leading to uneven marking results in laser marking machines? The utilization of laser marking machines is prevalent, particularly in the realm of handicraft products, garnering favor from customers.
Yet, equipment, akin to humans, undergoes wear and tear over time, resulting in various issues. This holds true for laser CNC engraving machines, potentially resulting in inadequate cleaning of surfaces.
Therefore, what precisely led to the irregular bottom of the CNC engraving machine? How can I address it independently? Today, I’ve compiled the following information for your consideration.
Uneven marking outcomes from a laser marking machine constitute a prevalent issue. This is chiefly identifiable by a noticeable bulge at the bottom during the marking process, along with a prominent vertical line between characters. The severity of this phenomenon increases with the intensity of the marking.
The reasons for the uneven marking effect are as follows.
1. The light output of the laser switching power supply is unstable.
2. The production and processing speed is too fast, and the response time of the laser tube cannot keep up.
3. The optical path is deviated or the focal length is wrong, resulting in transmitted light and uneven bottom.
4. The selection of focusing lenses is unscientific. You should choose short-focus lenses as much as possible to improve the quality of light.
The resolution to rectify the uneven marking effect is outlined below:
- Conduct a thorough examination by replacing the laser switch power supply.
- Decrease the processing speed to mitigate the issue.
- Verify the accuracy of the optical path to ensure proper alignment.
- When utilizing short focal length spectacle lenses, adjust the focal length considering the depth of the production process.
