A mate of mine has asked me to take a look at a manual bridgeport mill (I don't know which model) because neither the X or Y feed motors seem to be working. I'm guessing that it is unlikely that both motors will have packed up and it is possibly a supply problem. Spindle motor runs and the DRO fires up Main machine is 3 phase but what to the variable speed feed motors run off?? DC perhaps in order to get the speed control.
I just need a few clues before I turn up and look a complete ar$e as he is bound to be hanging round me expecting the miracle solution in minutes!!
