This grinding spindle came to us with the power leads cut off the stator. The incoming inspection showed contamination in both the front and rear bearings. When the customer cut the wires they were no longer able to connect the spindle as it is wound for high or low voltage. We were able to trace the leads and label them for easier installation. We assembled the spindle in our clean room with ABEC 7 bearings. After the completion of the assembly our technicians test ran the spindle at the top rated speed and trim balanced it. It was then put through our comprehensive final quality check and was approved for shipment.

This spindles front taper had worn to the point of needing a grind plate grind to bring it back to OEM specifications. The rear taper had run out but we were able to kiss grind it true. After we completed the work in our grinding department we manufactured replacement drive pins and assembled the spindle in our clean room. It was then broken in fully and test run at its maximum running speed. Vibration readings were taken and compared to our final QC criteria. All run out were check and passed. The spindle was then shipped to our customer.

The rear shaft threads on this spindle were worn and were cut into the pulley mounting surface. This caused irregular run out on the pulley resulting in vibration. We fixed the pulley mounting surface and cut new threads in our machining and grinding departments. We then assembled the spindle in our clean room, test ran and put it through our final quality check. The spindle is as good as new which is a good thing as no replacement spindles were available for the machine.
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.
