Re: CNC Aluminum: Recommended Speeds/Bits?

Step 0 with any CNC machine (IMO): get GWizard. Life will suck WAY less. It even has rigidity models, which will help guide your feeds and speeds by de-rating power on less-rigid machines like routers.

Here is a blog entry from the guy that makes GWizard. Worth a read. Then a re-read. Then another re-read after you try some of the suggestions.

110 is more than enough for a capable router table. My 4x4 Small Shop Machine is 110 and I've had good results cutting aluminum.

Are you at least running a serious air blast to make sure chips are not being re-cut? If neither of these then I think I know your problem...
