The GMN TS80CX142 spindle is designed and used as a tool and cutter grinding spindle. It comes fitted with a HSK style OD taper tooling system and is capable of running up to 10,000 rpm.
CHALLENGE
Our customer sent in this GMN TS80CX142 spindle from their walter grinding machine. The first thing we noted when this spindle arrived at Northland Tool and Electronics was that the the tooling threads were stripped out and the spindle was noisy when spun by hand. Once we completed a full breakdown and evaluation of the spindle we found that the A side housing had high taper and face runout and the A side shaft nut was not tight. Lastly, the B side bearings felt rough when spun by hand after disassembly. No other dimensional deviations were noted for this repair.
SOLUTION
The following actions were performed on this GMN TS80CX142 spindle:
- Clean, inspect overall dimensions
- Replace bearings, o-rings, and assembly screws
- Repair damaged ID threads
RESULT
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.
