Bridgeport VMC Weiss Spindle Repair
Our customer sent in a Bridgeport VMC Weiss spindle for repair. They wanted us to rebuild the spindle without the grease injection option as they are not happy with the spindle’s longevity when it uses grease injection as a lubrication method.
When this Bridgeport VMC Weiss spindle arrived to our facility we performed a full breakdown and evaluation. Upon inspection, we noted that the #1 bearing was contaminated, and the #2, #3, and #4 feel worn. Lastly, the gripper fingers were severely worn. No dimensional deviations were noted for this repair.
The following actions were performed on this Bridgeport VMC Weiss spindle:
- Clean, inspect overall dimensions
- Replace bearings, bellvilles, seals, grippers, and o-rings
- Convert from grease injection to grease pack
- Plug grease injection ports
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.
