Okamoto surface grinding spindle

This spindle failed from contamination to the front set of bearings. The taper also had 5 microns of run out. To prevent future failures from contamination Northland Tool re-engineered the front of the spindle adding a seal. This inexpensive modification could potentially increase the spindles life by many years. We then kiss ground the spindles tooling taper in our grinding department. Our technicians rebuilt the spindle to exacting tolerances and it was shipped back to our customer for installation.
