Akira Seiki V3XP Spindle Repair
The Akira Seiki V3XP is a CNC vertical machining center. It comes fitted with a grease lubricated and belt driven spindle that is capable of running up to 12,000 rpm.
CHALLENGE
Our customer sent in this Akira Seiki V3XP spindle stating that the spindle stopped working and was locked up. Once the spindle arrived at Northland Tool we completed a full disassembly and evaluation.
This is what we found:
- There was a black sludge (pic 1) contamination in the rear of the spindle and the rear radial bearings had catastrophically failed (pic 2).
- The rear radial bearing failure caused heavy damage to rear housing.
- The #3 and #4 bearings were heavily contaminated with a black sludge from the radials failing (pic 3).
- The front ID 40 taper had uneven contact and measured AT wrong on our air gauge system (pic 4).
- The grippers were heavily worn and needed to be replaced (pic 5).
SOLUTION
The following actions were performed on this Akira Seiki V3XP spindle:
- Replace Bolts, O-rings, Bearings, Bellevilles, and Grippers
- Grind-Plate-Grind (GPG) ID 40 taper due to uneven contact and air gauge measurement
- GPG rear 80mm housing due to severe damage caused by the radial bearing failure
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.
