HMC 200 Spindle Repair

HMC 200 Spindle Repair
2,400 rpm
50 Taper
This spindle had a damaged taper, 6 to 8 microns TIR, drive dog damage, damaged seal area, and bearing shoulders that had run out.
We were able to fix all the shaft dimensions with our Kellenburger ID/OD grinder. We manufactured a new drive dog and then assembled the rest of the spindle with new seals and bearings. The spindle is currently in the machine running and our customer says it’s making the best parts it has ever made.
