Cup-cutting machines

Hello.. Back in 1987..I read a "Lapidary Journal" article about an Italian machine that cut bowls or cups, using two diameters of a constant-radius semi-circular, bowl-like saw blade. Around the "lip" of the "cup"or "bowl" of the saw blade shape, would be situated the cutting diamonds, and the saw was spun AND rotated through 90 degrees to give a half-globe piece of stone product. By utilizing various diameters of blades, a bowl of down to 1/8 " thickness could be produced in a "reasonable" time period.
This machine was made in Milan, Italy, by a company (seenmingky now defunct) named "Taglieria Artigiana Pietre Dure" ( which roughly translates to : artisan gemstone cutting factory)........ I would love to know what became of them, if there are similar machines on the market, etc, etc.....HAS ANYONE EVER MADE AN AGATE OR JASPER BOWL ??? thanks, tony
