CHALLENGE

Our customer sent in this Hwacheon Vesta 1000 spindle stating that the spindle had failed.  When it arrived at Northland Tool we noted that it was completely seized so no incoming tests could be taken.  We then performed a full breakdown and evaluation where we recorded that the #2 bearing ball cage had melted and seized.

This caused the bearing to catastrophically fail and contaminate the #1 bearing.  Lastly, the ID 40 taper had pit marks throughout the taper and high run out.

 

SOLUTION

The following actions were performed on this Hwacheon Vesta 1000 spindle:

  • Clean, inspect overall dimensions
  • Replace bearings, bolts, o-rings, and bellevilles
  • Grind, plate, grind (GPG) the 40 ID Taper

 

RESULT

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.

This spindle passed our final quality inspection and was returned to our customer with a 1-year warranty.
