After a full breakdown and evaluation, we noted that the taper had high run out and was more of an oval shape on the air gauge than round. We also found that there was oil contamination in the bearings which was a dark brown color.
The following actions were performed on this Kitamura HX-300i spindle:
- Clean, inspect overall dimensions
- Replace bolts, bearings, and o-rings
- Grind, plate, grind (GPG) the ID tooling taper
After reassembly of all components and adjusting bearing preload, we put the spindle through a rigorous break-in and testing procedure to make sure it passes our final quality inspection.
