In terms of Speeds / Feeds, there is variance depending on your machine.

For Aluminium, 2 flute uncoated endmills are good. You did not mention depth or width of cut, or if you are slotting or not. You can try different methods, look up NYC CNC on Youtube, has many videos around Speeds and Feeds. Ideally you want to cut as deep as possible and take 10-15% of the Width as a cut. If you cant (because you are slotting), then Id probably go around at 1mm DOC at the speeds / feeds you mention. If you can vary your feeds during the cut, you will see and hear when the machine seems happiest.

Just keep the chips clear and some lube on the cutter. No need to overkill it.

You can see here, same size endmill, but loads more RPM and a sturdy machine = 4000 mm/min cutting, but lots (probably too much) lube.
