gravostar Process-integrated parts marking The manufacturing and marking of parts take place in one working sequence with the gravostar marking tool; i.e. each produced part leaves the cutting machine having already been equipped with the desired marking. The gravostar is predominantly used in machining centre and CNC lathes as a conventional machining tool, and practically all machinable materials up to a hardness of approx. 62 HRC can be marked. Benefits: + Time saving • o necessity for the separate process step for parts N marking • No additional parts handling for marking • Short...

1 2 1 Cost-effective parts marking on CNC lathe With gravostar there is no necessity for the use of driven tools. 2 Face-end marking of a drive shaft Functional principle of micro-percussion: Marking with gravostar: Contrary to engraving the micro-percussion process produces a fine, punctual compaction of the material rather than material waste or consumption. This takes place thanks to the vertical oscillation of the marking needle. The needle oscillation is brought about by the impulse control system, which is integrated into the tool. As soon as the air supply or internal cooling system...
