Hey there, fellow laser cutting enthusiasts! I'm a supplier of Enclosed Fiber Laser Cutters, and today I'm stoked to share some tips on how to adjust the power settings of these bad boys for different materials. It's super important to get the power settings right, 'cause that's what makes sure you get top - notch cuts every single time.
First off, let's talk about why power settings matter. The power of the laser determines how deep it can cut into a material and how clean the cut will be. If the power is too low, the laser might not cut through the material at all, or it'll leave a rough, uneven edge. On the other hand, if the power is too high, it can cause the material to melt, warp, or even catch fire. So, finding that sweet spot is key.
Cutting Mild Steel
Mild steel is one of the most common materials you'll cut with an enclosed fiber laser cutter. It's relatively easy to work with, but you still need to adjust the power settings based on its thickness.
For thin mild steel (less than 1mm), you can use a lower power setting. A power of around 20 - 30% of the maximum power of your Laser Cutting Machine with Full Cover should do the trick. The lower power helps prevent excessive melting and gives you a clean cut. You can also increase the cutting speed a bit, which saves time and still maintains a good cut quality.
As the thickness of the mild steel increases, you'll need to crank up the power. For 2 - 3mm thick mild steel, you might want to set the power to 40 - 50%. And for thicker mild steel, say 5 - 10mm, you could be looking at 60 - 80% power. But remember, as you increase the power, you'll probably need to slow down the cutting speed to ensure a complete cut.
Stainless Steel
Stainless steel is a bit more finicky than mild steel. It has a higher melting point and is more reflective, which means you need to be careful with the power settings.
When cutting thin stainless steel (less than 1mm), start with a power setting of around 30 - 40%. The higher power compared to mild steel is because of its higher melting point. You can also use a nitrogen assist gas, which helps to get a cleaner cut and prevent oxidation.
For 2 - 3mm thick stainless steel, increase the power to 50 - 60%. And for thicker stainless steel (5 - 10mm), you'll need to go up to 70 - 90% power. Again, adjust the cutting speed accordingly. A slower speed will give the laser more time to penetrate the material.
Aluminum
Aluminum is another popular material, but it's very reflective. This means that the laser can bounce off the surface, making it harder to cut.
For thin aluminum (less than 1mm), use a power setting of around 40 - 50%. You might also want to use a higher frequency setting to help the laser penetrate the material better.
When cutting 2 - 3mm thick aluminum, increase the power to 60 - 70%. And for thicker aluminum (5 - 10mm), you could be looking at 80 - 90% power. But be careful, as aluminum can melt quickly at high powers. You may need to experiment with the cutting speed and assist gas to get the best results.
Acrylic
Acrylic is a non - metallic material, and it requires a different approach. You don't want to use too much power, as it can cause the acrylic to crack or burn.
For thin acrylic (less than 5mm), a power setting of 10 - 20% is usually sufficient. You can increase the cutting speed to get a smooth cut. The lower power helps prevent the acrylic from melting and gives you a clear, clean edge.
For thicker acrylic (5 - 10mm), you can increase the power to 20 - 30%. But make sure to keep an eye on the cut quality, as too much power can still cause problems.
Wood
Wood is a natural material, and it also has different characteristics depending on the type of wood. Softwoods like pine are easier to cut than hardwoods like oak.
When cutting thin pine (less than 5mm), a power setting of 15 - 25% is a good starting point. You can use a higher cutting speed to prevent the wood from charring.
For thicker pine (5 - 10mm), increase the power to 25 - 35%. Hardwoods like oak will require a bit more power. For thin oak (less than 5mm), use 20 - 30% power, and for thicker oak (5 - 10mm), go up to 30 - 40% power.
Other Factors to Consider
It's not just about the power settings. There are other factors that can affect the cutting quality, such as the assist gas, cutting speed, and focal length.
Assist Gas: Different materials require different assist gases. For metals, oxygen is often used as an assist gas. It helps to oxidize the material, which makes it easier to cut. Nitrogen is also used, especially for stainless steel and aluminum, as it prevents oxidation and gives a cleaner cut. For non - metallic materials like acrylic and wood, compressed air can be used as an assist gas.
Cutting Speed: As mentioned earlier, the cutting speed is closely related to the power settings. Generally, as you increase the power, you'll need to decrease the cutting speed. But you can also fine - tune the speed to get the best cut quality. A slower speed might give you a cleaner cut, but it'll take longer.
Focal Length: The focal length of the laser beam affects how concentrated the laser is on the material. For thin materials, a shorter focal length can be used to get a more precise cut. For thicker materials, a longer focal length might be better, as it allows the laser to penetrate deeper.
Testing and Tweaking
The best way to find the perfect power settings for a particular material is to do some testing. Cut a small sample piece of the material and adjust the power, cutting speed, and other settings until you get the desired result. Keep a record of the settings that work well, so you can refer to them in the future.
