Hi. I used prototraks at a shop I worked at a few years ago. 2 were
Bridgeport retrofits and one was a larger model that was made by them.
(cannot remember the type) They were mx3's. (3 axis conversational
programing) They were very easy to use with the conversational
programing. One oddity I thought were the encoders on the machine.
They track against the cast iron via a metal wheel. You would think
that it wouldn't work, but it did quite well as long as you kept the
coolant out of them. (the encoder looks like a Travel Dial used on
many lathes I have seen. The are also made by Southwestern Ind.)
Anyhow, if you have any specific questions feel free to e-mail me at
the above address off group. Rick
