gravostar RMB-12
The unique feature of this process: the marking needle, which is spring-mounted and pre-tensioned in the axial direction, is equipped with a freely rotating solid carbide ball.
The marking contour is created by the compaction of the material left by the rolling action of the hard metal ball on the surface of the material.
Roller embossing is used for fine, visually high-quality marking and for applications where absolute freedom from burrs without any material throw-up is required. Even uneven marking surfaces can be provided with a consistent marking depth due to the spring-mounted marking needle with this tool type.
Field of application
Optically very high-quality, absolutely burr-free, fine marking
of any workpieces with regular, uneven or rough surfaces.
