The Colombo RV110.22 is a grease lubricated and stator driven CNC wood router spindle. This specific spindle is capable of running up to 24,000 rpm.
CHALLENGE
This Colombo RV110.22 spindle was seized when it arrived at Northland Tool and Electronics. Upon inspecting the spindle, we found that there was a catastrophic failure of the #1 bearing. The cage was completely destroyed. The rear bearings had a black particulate in the grease and felt rough when spun by hand. Lastly, the grippers and shaft taper were both in poor condition and the taper had very poor tool contact. No other dimensional deviations were noted for this repair.
SOLUTION
The following actions were performed on this Colombo RV110.22 spindle:
- Clean, inspect overall dimensions
- Replace bearings, bolts, o-rings, grippers, and bellevilles
- Kiss grind the 30 ID taper
RESULT
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.
