A computer-controlled engraving machine for objects in the form of rings, bracelets, medallions, etc., incorporates various types of securing elements to enable engraving by means of rotary movements in the elements supporting the object and longitudinal displacement movements and tilting movements in an engraving tool (26). A computer (44) is fed information on the required engraving and signals (i1, i2, i3) are generated in order to control the said rotary, longitudinal displacement and tilting movements. The longitudinal displacement function for the engraving tool is essentially play-free. Various types of objects are made possible. A rotary movements-effecting element includes a rotary movement-transforming element which transmits the rotary movement to a receiving element. |
