Fischer MFN-1045 Spindle Repair
The Fisher MFN-1045 spindle is from an ID grinding machine. It is oil mist lubricated and capable of running up to an impressive 45,000 rpm.
This Fischer MFN-1045 spindle arrived at our facility for a full breakdown and evaluation. Upon inspection, we noted that the front bearings had failed from excessive heat. We recommended to our customer that we replace the steel ball bearings that were in the spindle with some ceramic ball bearings. This change would allow the spindle to handle the high speed of 45,000 rpm while creating less heat. No dimensional deviations were noted for this repair.
The following actions were performed on this Fischer MFN-1045 spindle:
- Clean all parts of the spindle
- Replace all bolts and o-rings
- Replace steel ball bearings with ceramic equivalent
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.
