Unit marking done with laser marking station

  • Easily find the focal length thanks to the focusing diodes. Simply join the two laser diodes by adjusting the laser height with the motorized axis.
  • The laser automatically positions itself to the focal length at the start. You only have to enter the part height directly on the screen.
  • Thanks to the simulation mode, the station shows you the exact positioning of your future marking directly on the part.
Automated laser ideal for batch marking

LW2 is fully programmable to become an automated station:

  • All the marking files are pre-recorded by the supervisor on the station.
  • The entire marking process is programmable: marking informations, part height, time stamping, serialization, door opening/closing, I/O activation, etc...
  • The LW2 can then switch to operator mode.
  • No risk of errors, training free, just press a single button to start the next marking

The production mode allows you to go further in managing the traceability of your batches by connecting to your internal databases.

You thus connect the content of the marking to your databases and the history of the marked parts for an easier production process.

LW2 - Cobot

The marking station is controlled remotely, thanks to dedicated and programmable I/Os. It can be integrated into a robotic cell and associated with robots or cobots. The speed of door opening/closing has been optimized (2s) as well as the durability of our components to allow high volume production in a difficult environment. This allows you feel secure about integrating our laser station on your production line. Gravotech offers you a ready-to-integrate package.

Jewelry engraving accessories for laser stations

LW2 in Jewelry

Rotary device
In jewelry, most objects are cylindrical. By adding a rotary device to your LW2, you complete your offer in jewelry personalization. 
Engrave on the outside and inside of rings.

 

Pin table
Create an air flow under your base material during laser cutting to prevent overheating. By using the cutting pin table, you raise your material by 2 cm and avoid heat deformation, beam returns and colour degradation.

 

50W laser
With LW2, combine the speed of galvo technology and the power of a 50 Watt laser source. Be comfortable when cutting and fast when engraving for maximum efficiency.
