Anca Spindle Repair

This Anca reached the end of the bearings usable service life. Northland Tool and Electronics was able to fix the wear damage to the spindle taper by kiss grinding it on one of our Kellenburger grinders. We rebuilt the spindle in our clean room with new bearings and test ran it in our test room. The spindle is currently in a storage box as a spare until needed.
