Hurco VM1 Spindle Repair
The Hurco VM1 is a popular CNC vertical machining center. It comes equipped with a grease lubricated and belt driven spindle capable of running up to 8,000 rpm.
When this Hurco VM1 spindle arrived at Northland Tool and Electronics we completed a full breakdown and evaluation. Upon inspection, we found that the #1 front bearing failed from coolant contamination and does not feel smooth when rotated. The gripper fingers have significant wear, as seen in the pic below. Lastly, we measured the critical dimensions and found no dimensional deviations.
The following actions were performed on this Hurco VM1 spindle:
- Clean, inspect overall dimensions
- Replace bearings, gripper fingers, bellevilles, o-rings, and assembly screws
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.
