Hyundai-Kia VX650 Spindle Repair
The Hyundai-Kia VX650 is a large CNC vertical machining center. It can come equipped with a grease lubricated and pulley driven spindle that is capable of running up to 10,000 rpm.
This Hyundai-Kia VX650 spindle was seized incoming, therefore no incoming tests could be performed. After a complete disassembly and evaluation, we noted that the #1 and #2 bearings had catastrophically failed and there was severe contamination in the rear bearings. All of the bearings had no grease left in them. There were no dimensional deviations to note for this repair.
The following actions were performed on this Hyundai-Kia VX650 spindle:
- Clean, inspect overall dimensions
- Replace bolts, bearings, and o-rings
- Replace seals, gripper balls, and wear bands
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.
