RESEARCH OF ENGRAVING OF VARIOUS METALS AND ALLOYS, USED IN JEWELLERY PRODUCTION

The paper investigates the possibilities of engraving various metals and alloys used in jewellery production. The engraving of the samples was carried out in a glossy technique using mechanised processing on an engraving pneumatic system. As a result of the conducted experiments, the relationship between the quality of the engraved surface and the hardness and plasticity of materials is demonstrated. Conclusions and recommendations on the choice of optimal materials for engraving and adaptation of equipment modes for performing engraving work on various metals and alloys are formulated. These recommendations will be of interest to various specialists of jewellery production – jewellers, engravers, craftspeople working on en-graving pneumatic systems.
