I cant cut that with my spindle (not enought torque at lower speeds) and I was thinking to replace the 2.2kw water cooled spindle with a servo. What do you think? Is doable? What kind of servos whould I look for? Anybody done that?

Thank you

Can't you try doing it with lots of reallly shallow depth cuts at reasonable speed with small size carbide cutter?.
Then final full depth tiny edge skim.

The lack of torque can't be much worse than the spindle on a sieg x2 mill!!!!!.
