Fiber laser serie

The fibre laser marker is an identification marking solution dedicated to harsh environments.

Its aluminium cast housing is robust, rigid and dampens vibration and shocks. IP rating head Ip 54 for better protection of the galvo laser head and reduces long-term maintenance costs.

A dust filter is included within this high-speed laser marking machine. No cooling fan for electronics and source protection.


To facilitate and reduce the programming times of your PLCs, our Fibre laser engraver for metal is natively compatible with a wide range of communication protocols: Ethernet TCP/ IP, RS232, standard 8 I / 80, Dedicated I/O via DB-37 and optional industrial communication protocols like Profinet & Ethernet IP.

Lasertrace : our marking and identification software

Developed by Gravotech and enriched by numerous application experiences, it includes all the functions necessary for identification and traceability.

Serialise your parts easily, with text, serial numbers, logo, generate unique codes like Datamatrix, barcodes, QR codes, UID, GS1, and configure your variables, counters and shift codes.

Delivered as standard with each marking laser, Lasertrace allows you to create your marking files in a few clicks. Once the files have been transmitted to the control unit, your marking laser can operate autonomously or controlled by a PLC.

Metal marking laser machine on production line

This module guarantees you a precise and uniform laser marking, whatever the regularity of the pieces, or the complexity of their shape.

Simplify your galvo laser integration: no need to readjust the focal distance.

Easy programming.

Highest amplitude - choose the best solution on the market : Focal 160: up to 60 mm - Focal 254: up to 120 mm.

High-speed laser - reduce your marking cycle time : Less than 100ms to change the focal distance. Instant refocusing.

Steel laser engraving - multilevel

This unique system adapts to the marking surfaces instantaneous, without any laser head movement:

- No character deformation

- Uniform contrast over the entire engraving area

- Possibility of multiple laser markings on a single part at different levels

Metal laser marker using autofocus technology

This module automatically adjusts the laser focal distance without calibration or waiting time:
