First cut in aluminium. Disaster.

[A_Camera]

This thread actually reminded me that I had two gummed up roughing bits that I needed to sort out. totally welded solid and couldn't pick it off.

Bits before:

I had pictures like this in my mind before I decided to try and make my first cut in alu, so I was very surprised that it went so well for me.



I was so glad to see the aluminum chip spraying, and the end results were really nice.

Magic stuff:

Good to know in case I need it next time. Did some more aluminum since the first time and the results have been good so far.

I am using 4-flute, dry milling at pretty high RPM and feed rate and it seems to work well on the material I used so far.
