Fanuc Robodrill Spindle Rebuild
This Fanuc Robodrill spindle suffered a rear bearing failure due to a fretted and over sized rear housing. When our customer sent in the spindle they let us know that they would like to increase speed from 15,000 to 20,000 rpm.
Lastly, the housing OD had incoming damage from being removed out of the machine. No other dimensional deviations were noted for this repair.
The following actions were performed on this Fanuc Robodrill spindle:
- Clean, inspect overall dimensions
- Replace bearings with 20,000 rpm rated bearings
- Grind, chrome plate, and finish grind the housing
- Machine out the OD housing damage
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.
