Tips on Preventing Burn Marks When Laser Cutting Leather

When it comes to laser cutting leather, it is important to take the necessary precautions to ensure that you do not leave any unwanted burn marks on the leather. The laser cutting process requires precise settings to achieve a clean cut without any blemishes, and the wrong settings can result in a botched job.

To help you prevent burn marks when laser cutting leather, here are a few tips to consider.

1) Adjust Power Settings

When using a laser cutter to cut leather, it is important to adjust the power settings accordingly. It ensures that the laser is not too high, which can cause it to burn. If you need help with the correct power setting, consult the instruction manual of your laser cutting machine, as it will provide the most accurate settings for the best results.

2) Adjust Speed Settings

Burn marks are an inevitable result of laser cutting leather. While the precision of a laser cutter may be beneficial to a leatherworker, there is still a risk of the material being damaged by the intense heat generated by the laser. To prevent this, it’s important to adjust the speed settings before beginning a cut.

Firstly, you need to consider the thickness of the leather. Thicker leather requires a higher speed setting than thinner leather. This is because thicker leather takes longer to cut and requires more energy from the laser. If the speed is set too low, the laser won’t be able to penetrate the material enough to achieve an accurate cut.

Secondly, different machines have different power levels, so it’s important to adjust the speed settings accordingly. If you’re using a lower power machine, you’ll need to use a lower speed setting to ensure a clean, precise cut. On the other hand, if you’re using a higher power machine, you can use a higher speed setting without risking burn marks.

3) Use Appropriate Laser Focal Length

The laser focal length of your laser cutting machine is crucial when cutting leather. It determines the distance between the laser head and the leather and can affect the cutting precision.

If the focal length is longer, the laser head will be too far from the leather, resulting in a low cut. Conversely, if the focal length is too short, the laser will cut too deeply into the leather, potentially leaving burn marks.

4) Use Proper Nozzle Size

The nozzle size of the laser is also an important factor when laser cutting leather. The too-small nozzle can cause the laser to overheat, leading to burning marks on the leather. On the other hand, a nozzle that is too large can cause the laser to underperform, resulting in a poor cut. It is important to use the appropriate nozzle size for your laser cutter.

By following these tips, you can ensure that you get the best results when laser-cutting leather. With the right settings, your leather laser cutter will produce a clean, precise cut free of burn marks. Whether you are using a laser cutting machine for leather crafting, or a leather laser cutter for industrial applications, these tips will give you the best results.
