I don't understand why so many look down upon bridgeport mills. I hear of them being inaccurate and not sturdy enough but I just don't see it. A lot of the work I have done is on bridgeports and I have no issues with them being accurate or stout enough when used within reason. My current mill will put a 3" 6 insert shell mill through a piece of 2024 .150 deep at 15ipm and 3600rpm with no issues, steel is a bit slower and not as deep, but again...within reason. As far as accuracy we hit +/-.0005 or better all day long, x, y, and z. These aren't new machines, and the dro's could probably use some calibration but with measurement before going to the number to hit you can easily get it dead nuts. As measured with mit digital mics that read .00005 and starrett digital height gages with bs half thou indicators and readouts to .0005.
It's not a hard concept, if I can do it why can't you?
Ps, I used to run 17-4 in a 2 axis bridgeport cnc'd mill every day with the same results.
Sure tolerances are there for a reason, but why not make it perfect if it only takes a few more minutes.
