DECKEL MAHO GILDEMEISTER Franz Kessler
This Franz Kessler spindle was removed from a DMG (DECKEL MAHO GILDEMEISTER) machine by our customer who is a cnc retrofitter. The spindle had been crashed and had severe taper damage and a broken drive dog. The bearings had also been brinelled. We were able to replace the integrated drive dog and grind plate grind the taper. We then assembled the spindle with new ceramic bearings, balanced and test ran the spindle at full speed. After we checked the drawbar sensors and the rotary encoder to make sure they were functioning properly we shipped the spindle. The cost of our repair was less than 40% of the replacement spindle offered by DMG.
