I'm looking at producing camera accessories milled from 7075 aluminum. They're small, but somewhat complex, so the finish toolpaths are numerous and speed is fairly important if I want to produce more than one per day
I was planning on using an X3-type mill, but they're limited to 1750 rpm. I see the Taig mills get get as high as 11K rpm, which would allow some pretty awesome feed rates in theory.
However, someone has told me that the Taigs are not rigid enough to support even moderate feed rates regardless of rpm.
Is there anyone here with actual experience machining aluminum with the Taigs? What kind of feed rates are you getting?
Is there any way to increase the rigidity of the Taig with some kind of column bracing? I assume it's the column flex that's the problem.
