We are trying to cut a long part in our CNC turning center. I tried to start the operation with a real light facing. The bar jumped out of the 3 jaw Chuck we are using and won’t turn straight now. Maybe an issue with the soft Chuck jaws? I hate dealing with these automatic hydraulic chucks because it’s harder to get the stock perfectly centered in the jaws. Would a collet Chuck be a better option for this? Or maybe a manual self centering 6 jaw?
