Hardinge C42 Spindle Repair

5,000 rpm

The bearings in this spindle reached the end of their lifespan. The ID collet taper had 10 microns of run out. We were able to kiss grind the ID taper and after assembly it had less than 2 microns run out. The spindle was rebuilt in our clean room and test run at 5000 rpm. When our customer installs the spindle they should be able to run a short warm up procedure and then they will be ready to make parts.
