i wouldnt worry bout that my captain will move that much by just breakin an insert. this machine is a big dissappointment. my 7hp e-series has more power on the main spindle than my 30hp captain. i told the sales man that when he came in the other day and he just changed the subject. then he said what machine was on my wish list and i said another mazak.
i also have a shunk air chuck that doesnt hold on to anything with out a stopper plate.
o ya make sure the bolts holding the turret stay tight i have to tighten mine down about once a month.
