If aluminum is your main work material, you’re going to be putting some serious time in. The machine is capable if it’s your option.
As @Zach_Kaplan said, it’s all about the toolpaths.
Here are some pics and video of a recent Aluminum/Carvey job.
I ran this with a .125" spiral, single flute bit.
Feed 250mm/min.
Depth per pass was an experimental 3.5mm with an optimal load of 0.127mm. Generated in Fusion 360.
I ended up stopping every once in a while to remove chips and, eventually, add some WD-40.
