Had a toolholder pull out during a finish pass on a Mazak Integrex last Friday
I was running a stainless steel job, about 6 inches deep in a bore, when I heard that nasty grinding sound. The hydraulic collet let go and the whole holder spun in the spindle. Turns out the drawbar pressure was low, like under 800 psi when it should be 1200. Has anyone else had their machine drop pressure like that mid-run without throwing a warning?
