Maybe tighten the bolts down a little moreI recently bought a Bridgeport milling machine. I can tram it and get it square, make a pass and can check the squareness of the head and it will be out. Can anyone tell me what might cause this? Thanks I’m advance.
Also it will be out of square in both directions.
It’s not a round shaft model it’s a series one style.

A free loaded tram is not the same as in use. Why do not so many get this basic point.
Would be nice but not real world cutting metal.
Many cnc owners do the same duh with backlash comp.
A change from cut one to cut two can be cut loading and the fact that all is a spring matters.
How to solve? tram each time the load changes with the load in place?

Thanks everyone for the replies.
I square the head with a pro tram tool and then double check it with a test gauge setup on the spindle.
By pass I meant I was using a 1/2” end mill taking a .005” deep cut.
