machining Aluminium Tips?

[A_Camera]

First short video of machining aluminium. Still very new to this so any tips would be appreciated. I was playing with feeds and speeds during the test.

Started off with feed rate:

It is difficult to say anything regarding that video since I don't know how your machine looks like. To me it seems far too slow, but perhaps it is not possible to speed up more. Personally I'd prefer much faster speeds, like spindle speed 18krpm and feed rate 2700mm/min or maybe more. Here is a short video I made some time ago, milling at higher speed.



Note that I am using 4 flute bits, to me they work better. I don't use any lubricants, only the vac with dust shoe. That is enough, nothing gets hot if I don't slow down the feed rate too much and rub the bit.
