How to process back plate to guarantee
ER40
Collet Chuck's T.I.R?
Back plate can be mounted onto ER40
Collet Chuck
. As long as back plate Shoulder Diameter D1=3.78" > ER40
Collet Chuck's D1=3.74"
, all ER40
Collet Chuck
will fit in. 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. Note, for fully-machined back plate, D1 need to be processed before they can be mounted.
You would not need to drill any mounting holes but you will need to turn the shoulder down .040" to match the back of the lathe chuck to make the chuck & back plate more concentric with the lathe spindle. When turning the shoulder of the backing plate, ONLY TURN THE SHOULDER OF THE BACKING PLATE WHEN ATTACHED TO THE LATHE SPINDLE. If you use a chuck to clamp the backing plate and then turn it, the backing plate will not be true to the lathe spindle and will have more runout than specified when the chuck and back plate are put together.
How to minimize Chuck's TIR?
1. Before you buy the chuck please check your spindle's runout.
