My guess would be that these jigs are handmade by a master tool and die maker at a cost much too high for small quantity production of the pieces. (Although it's possible that someone has programmed the jig designs so they can be cut with CNC machines, or the jig pattern may be 3-D printed and somehow transferred to tool steel.) You need several jigs for the six different chess pieces. The queen's crown and rook's castellations require adding a cam to the lathe to make a cutter bob in and out as the piece turns. The bishop also needs a simple jig for a saw cut across the head. The knight's body and head are far more complicated; I guess that it's at least partly done with a mill rather than a lathe, as is the cross on the king's head.
A _good_ machinist could make a small run with a few cutting bits and only very simple jigs, but by making several separate cuts for even a pawn rather than the one-pass with the production jig you see in use here.
With some programming, the pieces themselves could be cut directly by CNC or 3-D printed. If you want the pieces made of wood, 3-D printing is out, and the CNC program is more complicated because the paths need to be laid out considering how the bits bite into the wood grain.
