CHALLENGE
Our customer sent in this Deckel Maho Ultrasonic 80F spindle stating that there were encoder issues. Once the spindle arrived at Northland Tool we completed a full disassembly and evaluation.
This is what we found:
- We found no issues with either of the encoders the customer sent in
- Spindle was difficult to rotate by hand and was received missing the front housing bolts
- The locking unit in the front of the shaft made contact with the journal and caused rub out damage
- Front and rear bearings felt okay when spun by hand
- Field passed incoming testing on our motor analyzer
- There were no proximity sensors sent in with the spindle
- The bearings are propriatary and will need to be replaced with standard bearings. We will need to
modify the housings to accommodate standard bearings
SOLUTION
The following actions were performed on this Deckel Maho Ultrasonic 80F spindle:
- Replace bolts, O-rings, Bearings, and Bellevilles
- Kiss grind ID of shaft locking unit
- Kiss grind journal where the locking unit caused rub out damage
- Grind-Plate-Grind both front housings and rear housing
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.
