Hi all,
My workplace is wanting to do CNC grinding on ceramic coatings on aerospace fins. Looking that the profile, they could certainly be ground in a 3 axis CNC machine. My question is more of related to machine longevity. Are there any machines well suited to this sort of work? Something I'm presuming with good coolant filtration and way coverings. Should I be looking into specific grinding machines?
Some specs
We have a CNC mill that I'm sure could do it, but it's limited to 15k spindle speed and is only used for graphite with no flood coolant of any sort.
Just getting me pointed in the right direction would be huge. I'm just a dumb engineer at a small company. I have no CNC manufacturing experience and I've already tapped out the guys at work.
TIA.

Some specs
- The current fins are about 4" long, so small work envelope. Maybe bigger in the future.
- I'd assume a wheel of about 2" diameter, but with the current geometry there is no reason they couldn't be bigger or smaller.
- There is currently no geometry that couldn't be done with a 3 axis mill and slightly rounded stone. I don't see a need for 4 or 5 axis.
- Tolerances are +/- 1 thou.
