Scoring heads also have two linear axes (like needle embossers), but are more stable than pure embossing heads. As higher transverse forces occur during needle scribing than during needle embossing, Östling’s scribing heads contain a spindle drive instead of a toothed belt drive. 0.4 mm marking depths are achieved during needle scribing.
Since the diamond / carbide tip does not oscillate during needle scribing like the carbide tip during needle embossing, but is pressed onto the workpiece to be marked, no large material unevenness can be compensated. In order to achieve uniform marking, the surface of the material to be marked must therefore be as even as possible.
