Setting the Parameters for a Leather Laser Engraver: A Guide to the Ideal Combination of Power and Speed

The company provides a laser cutting machine parameter guide for leather processing, which, through actual testing and case studies, helps users find the optimal combination of parameters, avoiding problems such as scorching or shallow cutting.These techniques are used to adjust for different leather thicknesses and precision requirements, improving work efficiency and product quality.

Why is the combination of power and speed so important?

When laser engraving leather, too much power can cause the edges to burn, while too fast a speed can make the image blurry.We have to adjust the parameters flexibly depending on the type of leather (such as top-grain leather and polyurethane), thickness, and desired depth of carving.For example, if you turn the power up all the way on a thin piece of material, you'll burn a hole in it in a matter of seconds. In this case, it's safer to lower the power and increase the speed.

The best way to find the best parameters is to practice.

Step One: First do a limited test.

Don ’ t rush to carve out the finished product! Use the scraps to make a series of small squares, and try out different combinations of power (for example, from 20 % to 80 %) and speed (300 mm / s to 800 mm / s).The key points to look at are the color change of the carving, and whether the leather has curled at the edges.

Step 2: Record your "formula.

During testing, you must always use your phone to take a picture of the results, and in your notes you must clearly record the corresponding parameters.For example, "lychee-patterned cowhide-1.5 mm thick: Power 45 % / speed 500 mm / s-Depth moderate, no scorch marks.In the future, when we encounter materials of the same type, we can simply consult the records and save half the time.

Emergency solutions for common problems.

The edges of the carving are yellow and singed.

The first thing to check is whether the power is beyond the range the material can withstand (especially for sensitive vegetable-tanned leather), or whether the machine lens is dusty, which can cause the energy to be focused incorrectly.In an emergency, you can reduce the power by 5-10 % and increase the speed by about 100 mm / s.

The lines of the patterns are broken.

This is generally caused by the laser head moving too quickly, and the energy not being able to keep up.It is recommended that you first reduce the speed (by 50mm / s each time), and at the same time observe whether power needs to be increased.If the image is complex, remember to turn on the "slow down at corners" function to prevent missing corners.

Long-term maintenance is key.

To maintain stable parameters, the focusing lens of the laser head needs to be cleaned at least once a month. Too much dust will affect the actual output power.When the temperature in the workshop is high in summer, it is recommended that the power output be reduced by 3-5 % to avoid fluctuations in energy due to poor heat dissipation.
