Design and build of a high precision spin grinding unit to be used on a surface grinder. This unit will be used to improve the precision of the Toolroom spindle parts shown in video #2 of the series to minimize the time required for final lapping. A method of lapping the rollers of the facial needle bearing to improve the runout from 10 microinches to 3 microinches is shown. The design of a differential screw system to provide 1 arc second resolution to the tilt system is covered.
