Haas VF-0 Spindle Repair
The Haas VF-0 is a CNC vertical machining center. It comes fitted with a grease lubricated and belt driven spindle that is capable of running up to 7,500 rpm.
When this Haas VF-0 spindle was disassembled and evaluated, we noted that spindle interior was full of coolant. From this coolant contamination, the grease in the front bearing pair was partially washed out and there was no grease at all in the single rear bearing. No dimensional deviations were noted for this repair.
The following actions were performed on this Haas VF-0 spindle:
- Clean, inspect overall dimensions
- Replace all bearings, o-rings, and assembly screws
- Replace bellevilles and gripper balls
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.
