This customer called and needed a spindle repair done within 5 days. We received the spindle and expedited the breakdown process. The rear roller bearing cage had failed causing the rolling elements to collide causing the spindle seizure. The Belleville washers for the drawbar were damaged and the taper was worn. The spindle repair was evaluated, quoted and approved within 24 hours. The shaft was kiss ground in our grinding department that specializes in spindle repair applications the same day the spindle was approved. Then the spindle went to our assembly area where the technician replaced the bearings and bellevilles. The technician adjusted preload, assembled and ran the spindle. Our quality control department inspected the spindle. The spindle repair was approved by the QC inspection process. The customer was very happy with our quick turn service and how we expedited everything through our facility.
