There are several CNC Mills on the market but very few that are
dedicated to the Jewelery modeling. Model Master is a good mill and
they have two mills. One is a basic mill with soft ware that cost
around $6,000 and then they have a full blown version that will do
rings and has a rotarty table etc and comes with training for two
operators ( two days ). This cost around $22,000.
