You see that the table moves out 0.05mm when I climb mill and goes back if I stop the cut. When doing light passes it doesnt happen, and finish is good.
It seems you already know the cause of the chatter.(chair)
Cutter load is not constant so if the table doesn't deflect under light load but deflects 0.05mm under higher load then a natural consequence would be chatter.
you still haven't answered the questions:
How old is the machine?
How mach use has the machine had?
The machine is from 1986.My guess is that it is well used over the years.
