Good Evening, I bought this 1500 watt fiber laser and have no issue cutting mild steel nor stainless up to .125 with no burrs, I am trying to cut 1/8" 6061 aluminum and no matter what I have tried I still have exit side burr about .015 to .030. Here is what I have tried
1.5mm,2.0mm, 2.5mm & 3mm nozzles: 2mm best so far
Nitrogen at 10 bar, 15 bar, 20 bar & 25 bar: 20 bar current was best
Nozzle height set at .015, tried .028, .035 and .04 and was bad
Focus point at -.119, -.09, -.08, -.07, -.06 & -.05: -.060 best result
Cutting speed at 2.1" per second current tried 1.3, 1.5, 1.8, 1.98, 2.1 and 2.4, 2.4 would cut must be to fast
Just trying to get rid of the underside burr, accuracy is cutting +/-.002 right now but burr is issue
Thanks for all the help and insight in advance!
Thanks,
Rick
