How to process back plate to guarantee Chuck's T.I.R?

The semi-machined back plate has to be processed into fully-machined which is showed in the above fig before they can be mounted. The fully-machined back plate can be mounted onto 5" 3 jaw or 4 jaw self centering and independent lathe chuck (p/n 202-5594)All back plates have 0.04" allowance, please measure the size of Chuck's D1 before process your back plates. The size of back plates's D1 should be a little bit smaller than the size of Chuck's D1. Because the gap between back plate and chuck is smaller, chuck's TIR is better. No gap is the best.
