Hello everybody,
I need to make a lot of parts from 4' long bars, O.D. is 1.750" we don't touch it, inside boring to 3.150" depth, eccentric tolerance is .005 ". I use a bar puller and put 3 plastic sealing rings inside the machine tube. There is almost no runout near the collet, but at the end of the bar it is about .01 ", but not always, sometimes runout is OK - .002", I cannot fix this problem. What to do? Can the Spindle Liner help?
