I also thought about using PWM servo amps. But not all of them support
tacho-generators, which I would like to reuse, since they are tightly
coupled to the servo motors in my machine.

Yeah, that's another problem. IIRC originally the machine was used to
polish ceramic-like materials. I guess more powerful servo motors were
not necessary for this application. Which motor power rating would you
recommend for a desktop mill?
