Engraving Machine

a machine for mechanical engraving from a drawing, stencil, or model. An engraving machine is used to transfer representations from bas-reliefs and other convex artistic originals to soft metal (such as copper), stone, or wood. In metalworking the engraving machine is a small copying-milling machine with a pantograph, carrying a cutting instrument (cutter or graver), which cuts the stamps, inscriptions, and figures on machined parts. An engraving machine is used in polygraphy to prepare zincographic stereotypes.
