i'm sure it has already been asked, but i'm new to the VFD and had some questions on whether or not what i want to do is the best route to go or not.
We just picked up an early 70's bridgeport series 1 9x42 with the 1hp step pulley head on it. i like the reliability of the step pulley head, but i don't like the limited speeds available as well as having to change the belt for the adjustment.
the shop we're in has 240v 3 phase service, so i could just wire it up and not worry about it, but i've been reading about the vfd's and i'd like to use that for the speed control.
the questions i have are:
1. is this a smart way to go, or does it end up being more of a headache in the long run.
2. can someone point me to a good vfd to use with this mill?
3. should i get a braking resistor for when i'm tapping on the mill? or will the internal resistor in most vfd's be enough to quickly go from fwd to reverse?
thanks for the help
