Myford Spindle Repair

Myford Spindle Repair



CHALLENGE

This Myford spindle arrived broken down to Northland Tool and Electronics.  Upon disassembly, we noted that the bronze bearing shows signs of rub out with the shaft.  The rear 30mm shaft journal was undersized +3/-9 and tapered (ISO is +/-3.5).  Lastly, the rear 62mm housing was oversized +8/+15 (ISO is +/-6.5).

 

SOLUTION

The following actions were performed on this Myford spindle:

  • Clean, inspect overall dimensions
  • Replace roller bearings, seals, and re-scrape the bronze bearing
  • Grind, chrome plate, and finish grind the 62mm rear housing and 30mm rear shaft journal

 

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.
