Bridgeport Manual to CNC conversion...

Am i missing something? Why you need 750w servos on a Bridgeport. 400w will do the job

Ye, I think it was a question from someone else and it's gone off topic a bit. Nothing to do with this thread I think.

To be honest, Colin if your converting a Bridge port then I would seriously consider Closed-Loop steppers because they will easily match the performance that Bridgeport limits you too. In my opinion, Servos are a costly and complicated overkill for a bridge port.

Now Stepper technology as got so much better with Digital drives and Closed-loop feedback then they are a good match for Older machines like Bridge ports.
The secret is using the correct drives and sizing the motor. The Lichuan mains-powered drives that I use with 9Nm 3 phase motors will easily handle anything a Bridgeport will throw at them and are quite a bit Cheaper than cheap Chinese servos. They are simple devices with hardly any setting up required, just Fit and use.
