Robotic Thermal Cutting Machine

Voortman V808

The Voortman V808 is the most versatile and market leading robotic thermal cutting machine with 8-axis. The extreme flexibility of the robot in combination with the machine structure enables the machine to cut every 3D shape possible and mark all four sides of your material. This system allows for enormous freedom to design and produce structures with the most complex connections and copes, but also a significant increase in production speed.

The Voortman V808 robotic thermal cutting machine is equipped with the new faster and more accurate versatile Panasonic TL-1800G3 coping robot.

Surface Treatment

Shot blasting

Shot blasting is used to clean surface until S2.5-3.0 and to gain roughness 45-70 mkm before painting.

We have 2 shot blasting cameras each 6x18x5 m. Max weight to shot blast in one time is 5 tons.

Painting

At our factory we have 2 heatable (+18 °C in winter) painting facilities each 18x90x5 m large. Totally our paintshop is more than 3000 m² big.
Each facility have 2x5t cranes, so it is possible to paint 10t heavy constructions in one piece. Typically we are using epoxy or polyurethane paints EN ISO 12944-5 prime/finish system. We can offer any paint system and tone according to EN ISO 12944-5 standard.
