Hello PM Nation,
I searched around Google and you tube but I am trying to find information on how the power transmission works on a Bridgeport.
Looking at them I am trying to see from the Motor on the head, belts, worm gears? I believe control the speed.
I am then also tryin to understand how the vertical linear travel is designed.
I see you can manually and also servo control the the vertical travel of the spindle but still confused how exactly it is done.
I see a threaded rod and something called a power quill but does the spindle travel up and down through a linear bushing and shaft?
Just trying to understand and am hoping you know of sources or can explain how the millers work through the generational releases from manual to servo controlled.
Thanks for reading
John
