Depth of laser marking|How to Adjust Laser Engraving Depth and Clarity
Want to adjust the depth and clarity of the markings made by your laser marker? This course will teach you the core parameters of power, speed, and frequency, and how to set them. You will also learn how to adjust the focal length according to the material, and how to clean the mirrors, to solve the problem of blurry or too-shallow markings.Through real-life case studies, this book demonstrates the method of linking depth and clarity adjustment, enabling the reader to quickly master the essentials of laser marking machine adjustment and improve product marking quality.
In order to adjust the depth and clarity of the laser marking machine, both the hardware parameters and the operation process must be taken into account.The first thing to pay attention to is the laser power setting--the higher the power, the deeper the etching, but too high a power setting will cause the material to burn.It is suggested that testing begin at 60 % power and gradually increase to 80 % for metal materials.The next thing to consider is speed. The faster the laser moves, the less deep the etch. For fine patterns, a speed of 2000mm / s or less is recommended.The frequency parameter affects the number of laser pulses per unit area. A high frequency is suitable for lighter-colored materials to increase the intensity of the coloration, while a low frequency is suitable for deep engraving.
Focusing is a key step in achieving a sharp image.Different materials require different focal lengths. Metals usually require a shorter focal length (5-8 cm), while plastics require the standard focal length (10 cm).After each material change, the operator should use the focus block to calibrate the machine.If the edges of the letters appear blurry, check to see if the galvanometer is out of alignment or if there is a speck on the lens. We recommend cleaning the lens with alcohol once a month.
When operating, you can first use scrap to conduct a gradient test: Fix the speed value and adjust the power in 10 % increments to make a parameter comparison sample.The best parameters are recorded.For reflective materials, the frequency can be lowered and the work table angle adjusted to avoid laser reflection that would affect the clarity of the image.Regular maintenance of the laser and cooling system can ensure stable power output. It is recommended that the laser's output power be tested every quarter to see if it has diminished.
