Belt driven

ID grinding spindle

The cause of failure of this spindle was coolant contamination and a worn tooling taper. We like a piece of our customers tooling with every repair we do. It allows us to do a more comprehensive check on not only the spindle but the influence the tooling mating surfaces may be having on the performance of the spindle.  Our evaluation showed that the customers tooling had worn over time and we recommended replacing the critical wheel holders. Our customer called us after they installed the spindle thanking us for giving them a grinder that performs like it was new.
