Unit marking done with laser marking station

The LW2 offers a number of setting aids on the touch screen for individual use:

  • Easily find the focal length thanks to the focusing diodes. Simply join the two laser spots by adjusting the laser height with the motorized axis.
  • The automated laser cutter 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 laser marking station:

  • All the marking files are pre-loaded by the supervisor.
  • The entire marking process is programmable: marking information, 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 industrial laser engraver 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 mass marking in a difficult environment. This allows you to feel secure about integrating our industrial laser engraver 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.
