We repair many spindles from customers in Canada. This customer sent us a Hurco HS100842 spindle for repair. After breaking down the spindle for evaluation we discovered that the #1 front bearing had failed. The shaft taper had 4 microns runout and the front shoulder had 3-4 microns runout.
The following actions were performed on this Hurco HS100842 spindle:
- Clean, inspect overall dimensions
- Replace bearings, o-rings, assembly screws, and bellevilles
