The Chiron FZ 18 is a high production vertical machining center equipped with a high speed spindle. It is coupling driven and capable of running up to 12,000 rpm.
When this Chiron FZ 18 spindle arrived at Northland Tool and Electronics it was fully evaluated to determine the possible cause of failure. Upon inspection we found quite a few issues that need to be addressed. First the bearings were severely contaminated and the front bearing spacer was bent. Second the HSK 63 taper had deep pock marks and the face of the gripper finger ejector pin was worn. Lastly the drawbar shaft had spring wear on it and will need to be ground.
The following actions were performed on this Chiron FZ 18 spindle:
- Clean all parts of the spindle
- Replace all bolts, o-rings, and bellevilles
- Replace gripper assembly
- Replace bearings
- Replace front bearing spacer
- Replace injector pin
- Grind-Plate-Grind ID taper and drawbar shaft
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.
