Daewoo Minx 500

8,000 rpm
40 Taper

Spindle had 25 microns of run out in the taper and was contaminated with coolant causing the bearings to fail. Our evaluation determined that coolant was entering the spindle through the front labyrinth. We ground plate ground the taper and manufactured new labyrinth interfaces to improve contamination resistance. We then replaced the bearings, rebuilt the spindle, test ran it at speed, balance and final QC before shipment.
