It was aluminum.
It turns out, that my mill is able to cut aluminum. But man, that was loud!
The quiet before the storm:
The real deal (with lots of cutting oil on it):
Tools & Settings:
- 2mm aluminum
- Dremel 400 Digital
- Tungsten carbide 3mm mill bit
- 20000 RPM
- Feedrate 100 mm/minute
- .3 mm depth per cut
- lots of cutting oil
I guess I could increase the feedrate a bit, but I should lower the depth per cut to probably .2mm
All in all, I’m very exited. But really: It was LOUD!!
And here’s the inevitable video:
