FIELD: process engineering.
SUBSTANCE: invention relates to machine-tool construction, particularly, to machining of hard flat surfaces, primarily, in fancy and decorative works. Magnetic impact engraving head comprises the case, solenoid, core engraving needle. Note here that said core is rigidly coupled with moving circular permanent magnets while said case is furnished with damper and fixed permanent circular magnets. Note also said moving circular permanent magnets are arranged concentrically with clearance inside fixed magnets opposite each other while engraving needle is arranged at plate spring secured at the case.
