The Boneham & Turner GS6580 is a high speed grinding spindle. It is grease lubricated, pulley driven, and capable of running up to 28,000 rpm.
CHALLENGE
This Boneham & Turner GS6580 spindle was difficult to rotate by hand, therefore no incoming runout could be taken. During disassembly, we noted that all of the bearings separated during breakdown. Once the breakdown was completed, we noted that the bearings were contaminated with a brown particulate. The spindle was then evaluated and the critical surfaces were measured. We found that both the front and rear bearing journals had deviation and will need to be ground. Lastly, the ID taper had high run out and will need grinding as well.
SOLUTION
The following actions were performed on this Boneham & Turner GS6580 spindle:
- Clean, inspect overall dimensions
- Replace bearings, o-rings, and assembly screws
- Grind, chrome plate, and finish grind (GPG) the front ID Taper
- GPG the front and rear bearing journals
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.
