Gravotech - LW2 marking station

LW3

LASER STATION
LW3: High volume industrial laser station
LW3 - Gravotech
The only Gravotech class 1 laser enclosure for large direct part marking. The LW3 brings security and marking versatility to the workplace.
  • LARGE MARKING POSSIBILITIES
    With its 3-sided door, the LW3 benefits from the best inside height dimensions and can securely envelop and mark parts up to 628 mm high. Thanks to its compatibility with our Fibre, Hybrid, Green industrial laser series, the LW3 can mark with high precision nearly every metal or plastic surfaces on its special positioning table.
     
  • VERSATILE
    From unique identification marking, to multi-level engraving, and matrix marking on a batch of small to medium parts, this industrial laser station can mark your large part at several positions, and levels. Add a 3D module to your LW3 laser to mark sloped parts.
     
  • INDUSTRY ORIENTED
    This laser marking machine is the only large laser engraver of the market with an attached touchscreen allowing the operator to easily manage the direct part marking process. In addition to the easy installation, manutention, and silent/ergonomic door opening, this class 1 laser stands out with its exceptional build quality.

Technical specifications

New ZX bridge
The LW3 is also available with a ZX bridge configuration, that enables the laser head to move along those 2 axes.
It can now mark very large parts from one end to the other, extending the effective marking area from 300 x 300 mm to 875 x 300 mm (34.45 x 11.81 in).

Integrated touchscreen
Control the marking process with the 7 inch color touchscreen.
Select jobs that are loaded in the machine and securely mark your parts.

Automatic and secure door
The 3 sided-door has been designed for ease of access and easy loading of the part.
When the marking job starts, the door automatically closes, and then reopens when it finishes. You can check the state of the permanent marking through the 380 x 210 mm protective window.
In addition, its opening adds no extra height to this class 1 laser machine.

Mark and identify large parts with our LW3 Laser workstation

The way the LW3 is built offers many possibilities for large direct part marking.

Obviously the size of this workstation inherently allows for big parts to fit in and receive their unique identifying number.
Indeed the enclosure has one of the best indoor heights, and can hence host parts up to 628 mm high.

In addition, this industrial laser station is equipped with a large metal table with rails and grooves for part and holder positionning.

If you need to mark parts bigger than the LW3, a Class 4 override accessory can permit marking while the door is open.

LW2 safety door

Thanks to its Class 1 laser certification (international standard for the highest laser security level), the LW3 ensures that the operator and workplace stays safe.

The door automatically closes before the marking is launched, securing the laser beam within the laser marking machine’s enclosure. The operator can then observe the laser marking through the dedicated secure window, without needing protective glasses. In addition, sensors check if the door is closed.

Finally, the LW3 and touchscreen are ready to pilot an exhaust system, for smoke and particle extraction. Because, during the laser marking, fumes and particles can be generated and need to be extracted to proper filtration systems.

Simplified interface for operators

The LW3 is one of the few industrial laser stations to not continuously require a PC or laptop to work.

Would it be a barcode, 2D code, text, date or logo, the marking job is created thanks to one of our industrial software: Lasertrace or Gravostyle™. It is then sent and hosted within the LW3.

This means that the marking files are accessed and launched through the attached touchscreen, adding autonomy to our workstation.

Production mode

This laser marking machine can mark large, but also series of small to medium parts. This marking method is also referred as batch marking.
With its available marking area and the optional ZX bridge’s stroke, the laser marking head placed within the LW3 can mark lots of parts.

As a supervisor, you can program every step of the batch marking process through our industrial software:

  • marking information
  • part height
  • input/output (i/o) signal activation
  • time stamping
  • text prompt on touchscreen
  • acquisition with barcode reader
  • etc.

This preparation drastically reduces operator errors. The press of a button launches the batch marking.

LW3 laser workstation on its support trolley for easy movement

Manageable industrial laser

For a galvanometric laser station of its size, the LW3 only weighs 200 kg.

When positioned on our dedicated trolley, it then can easily be moved around for commissioning, or if its permanent marking capabilities are needed elsewhere.

The workstation trolley, optional wheels and relative light weight make the LW3 an easy to move large laser engraver. You can reassign and adapt it to various industrial creation processes.
