Product catalog summary
Overview: Gravostar provides integrated tool solutions for parts marking in manufacturing processes, particularly in machining centers and CNC lathes. The tool allows for marking during the production sequence, eliminating the need for separate marking steps.
Key Benefits:
  • Time Saving: No separate process step or additional handling for marking; marking time is approximately 1 second per digit.
  • Reliability: Ensures no missed or incorrect markings.
  • Automation: Marking is integrated into the processing program with data adoption from databases.
  • Customization: Variable shape and size of markings, including serial numbers and logos for traceability.
  • Versatility: Suitable for various surfaces, including raw cast and uneven surfaces, with automatic compensation for dimensional differences.
  • Material Integrity: Non-cutting process that does not weaken material fibers, suitable for thin and stressed workpieces.
  • Operational Reliability: Dependable process with a wear-free marking needle (92 HRC hardness).
Technical Specifications:
  • Micro-percussion process with a vertical oscillation frequency of 300 Hz.
  • Marking depth adjustable up to 0.3 mm, with a maximum hardness of 62 HRC for marking surfaces.
  • Feed speed up to 5,000 mm/min.
  • Distance compensation up to 8 mm depending on the tool type.
  • Needle drive options include internal tool cooling or compressed air.
Application Options: Primarily used in processing centers and CNC lathes, with height compensation for uneven surfaces ensuring consistent marking depth.
Alternative Tools: The R-20 scratching tool is available for fine markings, equipped with a standard Weldon 20 shank shaft, with special models available upon request.

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 marking...

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 are...
