I spotted a link to a video from a link someone posted recently, and that began a series of interesting discoveries of other drill sharpening machines and methods
Kaindl a German company

Viel a Canadian company, but a location in the USA

You might notice that both of the above methods utilize a segmented chuck? holder for the drills. A similar type holder is used for the TDR SRD drill sharpening machines

The segmented drill holder makes it easy for the operator to flip the holder over and have the 2 drill point sharpening positions indexed 180 degrees apart (without remounting the drill in the holder).Videos of Viel and Kaindl
