I've seen someone here report on doing it just that way for commercial
mowers.


That'd be me.

Oregon makes the blades for the Scagg 61" commercial mowers. They are
_adamant_ about milling them with a face mill rather than grinding them.

They supply them as new milled, and they specify the angle and remaining
width of cutting backup area for new milling. Until they become narrower
than spec, you just keep on milling new faces. I get about 30 acres per
sharpening for a three-blade set now, up from my original 18. It has
more to do with the fact that I've finally cut up and and not now re-
cutting all the thatch than with the method.

I built up a permanent angle jig out of a block of 6061 to hold mine, and
use a small carbide insert face mill to produce the edges.

One benefit is that it never overheats the metal. The other is that they
come out virtually perfectly balanced every time.

Maybe you could take a picture and post it next time you have it setup.
