We received this from a company that produces precision parts for the medical, automotive and electronics industries. The spindle had 70 microns of run out in the taper. The customer needed better run out in order to provide their customers with quality parts.
It was determined that the taper would need grind, chrome plate and finish grind. The shaft was sent into our grinding department and they were able to bring the taper back to 2 microns of run out. After assembly and inspection the spindle was sent to the customer. They were very satisfied with the run out on the spindle and its performance in the machine.
