.125 aluminum on a 1500 watt laser

[Rocketman1962]

This is my first time posting on here, hopefully someone can help. I have a '90 Mazak TX-48 1500 watt laser. I've been cutting various
cold rolled steel thicknesses with good results and even .062 aluminum. I'm not having any luck with .125 aluminum with this cutting
condition;

Any help would be greatly appreciated. Thank you, Ron

I run a 89 mazak laser path that is also a 1500 watt. We cut .125" aluminum quite a bit with no problems. I would start with at least 1300 watts but run it contiuous wave (100% duty) with the feed at around 30-35 ipm. Other than that I use a standard 1.5mm nozzle with at least 130 psi. Nitrogen assist gas is prefered but oxygen seems to be good enough for me. I also use a standard focus which may not be the most optimum set up but this gets the job done for me as well. If I remember correctly 5000 or 6000 series aluminum is all we run too, so I would check to make sure the grade of material you are running is ok to laser cut. Hope this helps.

I will definitely give this a try tomorrow, thank you.
