GMN TS100CX170 Spindle Repair
The GMN TS100CX170 is a grease lubricated 10,000 RPM spindle. This spindle is used in a precision tool grinding machine in the cutting tool industry.
When this spindle arrived at Northland Tool and Electronics it was completely seized. Once the spindle was disassembled it was found that the front bearings were completely dry and contaminated. The ball cages were broken in both the #1 and #2 bearings with cage dust and contamination throughout. The rear bearings had clean grease but felt worn. The front housing nut was difficult to remove and was damaged during breakdown. There were no critical dimensional deviations found on this spindle.
The following actions were performed on this GMN TS100CX170 spindle repair:
- Clean all parts of the spindle
- Replace all bolts and o-rings
- Replace bearings
- Machine new front housing nut
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.
