.125 Aluminum cutting. Need to reduce dross. Amada FLCAJ Fiber
(OP)
I'm running a 4kw fiber laser and we just got an order for 11 ga aluminum. Our customer is making tanks and these parts are all exposed. Our initial test run of the material left dross that the owner wasn't happy with. Can anybody help me with some tricks for cutting a burr free aluminum?
Thanks.
Thanks.

What are your cutting conditions?
I have had success cutting Aluminum before with a Precitec head with an IPG laser on 4mm AL. Like footstrap said, it won't be completely burr free but it was pretty good and there will be striations. I can possibly show you pictures later.
I recommend a 200 microns focus spot and going relatively slow about 30-50mm. I also used a 2mm double nozzle and high pressure nitrogen gas.

250 IPM
1.5 bar N2
-0.02 Focus
Edge quality is less of a concern than the burr.
