The initial concern for this customer was the sound of the bearings during rotation. Upon further inspection the temperature of the spindle had elevated. This was caused by contamination in the bearings, both front and rear.

Our evaluation showed run out in the taper and face on the front of the shaft. We kiss ground the tooling interface in our grinding department. The spindle repair was then moved to our clean room were it received a complete rebuild and replacement of all wear items including bearings. We adjusted the preload, balanced, assembled and sent the spindle through our final QC inspection. Once all this was done the spindle was returned to the customer.
