We smacked our BT40 Kitamura pretty hard. I threw a toolholder up in the spindle and it checked .002 tir runout. I ordered a 40 taper testbar in order to accurately measure the runout. It will be here in a couple of days.

I didn't feel anything in the spindle like a burr etc.. I don't hear any unusual noises either.

My question is; How do you check for a bent spindle? Am I on the right track here? Any advice is greatly appreciated.

Thanks

Don
