Gamfior E14127 Spindle Repair
The Gamfior E14127 is a grease lubricated and stator driven spindle capable of running up to 12,000 rpm.
When this Gamfior E14127 spindle arrived at Northland Tool and Electronics we completed a full breakdown and evaluation. Upon inspection we found quite a few issues to be addressed. First, the shaft taper had 32 microns of runout, which is unacceptable. Second, the drawbar sensor was not functioning and the encoder sensor disc was stained with rust and untestable. Third, the front housing cover had a large gouge. Lastly, the gripper ball holder was very rusted and all the o-rings and seals were worn.
The following actions were performed on this Gamfior E14127 spindle:
- Clean, inspect overall dimensions.
- Grind, chrome plate and finish grind the taper.
- Machine the front housing cover.
- Replace bearings, drawbar sleeve, optical encoder, sensor disc, actuator seals, orings and screws.
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.
