yes, make sure the gibs are tightened and the ball screw bearings also tight. there will always be some degree of flex on every machine, but i think this one should be a bit better than .004" with just light hand force (30-40lbs).
for the gibs, youll have to pull up on the head somehow. an easy way is by resting the spindle nose on a block of wood. then youll find you can tighten them significantly better than if the spindle is just hanging normally. |
