OKK VP500 2APC Spindle Repair
The OKK VP500 2APC is a bridge style CNC vertical machining center. It comes fitted with a grease lubricated and stator driven spindle capable of running up to 12,000 rpm.
When this OKK VP500 2APC arrived at Northland Tool and Electronics we completed a full breakdown and evaluation. After inspection, we noted that the front bearings had suffered a catastrophic failure, the cages were broken. The rotary union ceramic button was cracked, allowing coolant into the spindle. Lastly, the bellevilles and o-rings were worn.
The following actions were performed on this OKK VP500 2APC spindle:
- Clean, inspect overall dimensions.
- Replace bearings, o-rings, and bellevilles
- Customer supplied new rear bearing (we will not install.)
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.
