flat (50um or .001" over the module area) clean is important.<

Not sure that I would agree about a fly cutter. Better than nothing, but I 
would prefer 
a horizontal milling cutter. Alternatively, a face-and-end milling cutter. 
A large slot drill 
might give a good enough finish.

Another good way would be to use a shaping machine.
