Abstract

Il presente trovato si riferisce ad una macchina per la sfaccettatura di pietre preziose e non preziose, particolarmente per la realizzazione di monili. La macchina comprende un mandrino che è provvisto di mezzi di presa di una pietra da sfaccettare e un utensile che è mobile a comando in avvicinamento o in allontanamento al mandrino per interferire con la pietra posta su tale mandrino. Il mandrino è posto su un supporto che è girevole a comando attorno ad un asse coincidente sostanzialmente con l'asse del mandrino e sono previsti mezzi di comando che generano una rotazione ad intermittenza del supporto secondo angoli di ampiezza prefissata e l'utensile è costituito da una mola azionabile con moto rotatorio attorno al suo asse e mobile a comando in avvicinamento o in allontanamento al mandrino per abradere in sequenza porzioni della pietra portate, mediante la rotazione intermittente del supporto, nella zona di azione della mola.The present invention relates to a machine for faceting precious and non-precious stones, particularly for making jewelery. The machine comprises a mandrel which is provided with means for gripping a stone to be faceted and a tool which is movable on command towards or away from the mandrel to interfere with the stone placed on said mandrel. The mandrel is placed on a support which is rotatable on command about an axis coinciding substantially with the axis of the mandrel and control means are provided which generate an intermittent rotation of the support according to angles of predetermined width and the tool consists of a grinding wheel which can be activated with a rotary motion around its axis and which is movable when moving towards or away from the spindle to sequentially abrade portions of the stone carried, by means of the intermittent rotation of the support, in the area of action of the grinding wheel.
