Success Stories of Motor City Repairing Okuma Spindles

Model:  4000 Tooling:  Big Plus 40 Max RPM: 10,000


Work Scope

  • The OEM quoted the customer $ 30,000 and a 4-6 week lead time for a new spindle.  We were able to provide them with a rebuilt unit for less than 10,000 K with a two week lead time.  The customer couldn’t have been more pleased with the result and it paid off for us as well.  They sent us two more spindles since, so it was a win win.
  • Tested, Cleaned and baked spindle motor stator.
  • Chrome and grind of ID taper to Big Plus 40 tooling size specifications.
  • Replaced ceramic ball bearings and steel roller bearings.
  • Replaced o-rings.
