Arnold Ravensburg / coaxworks cooperation
The machine factory Arnold GmbH from Ravensburg has developed and delivered a laser system for additive manufacturing using welding wire for a well-known customer from Switzerland.
A 3D laser system from the PremiumLine series was further developed and adapted to customer-specific requirements. The result is the GNT-200 model. The PremiumLine is now offered for component sizes from 2000 mm to 5000 mm with various beam sources such as fiber, disc, diode and CO2 lasers.
The GNT-200 is designed as a gantry system and offers up to seven NC-controlled axes (XYZB-C1-A-C2). The processing optics are adjusted horizontally (X & Y), vertically (Z), tiltable (B) and rotatable (C1). The component is clamped on the faceplate of the rotary swivel axis (A-C2). All axes are involved in several transformations, so simple 2D to complex 3D geometries can be manufactured. A solid-state laser with a laser power of up to 8 kW is used as the beam source.
A key feature of the system is the processing optics from coaxworks GmbH . The wireM laser welding head has a 3-beam design with integrated coaxial wire feed. Using the wireM allows the welding process to be direction-independent, enabling the application of coatings not only to rotationally symmetrical but also to flat and freeform component surfaces. The precise energy input results in a very uniform weld seam with minimal heat input into the component. By selecting the laser power (≤4 kW) and wire diameter (0,8 / 1,0 / 1,2 mm), the layer thickness can be varied, thus applying only the necessary amount of material in a cost-effective manner. Complete utilization of the welding wire ensures exceptionally clean process conditions for both operator and machine. Furthermore, the integrated collision protection shutdown, a unique technical feature, protects the laser system for a long service life in practical use.
The compact footprint and gantry construction allow for easy transport and quick re-commissioning at the end customer.
The new PremiumLine series is predestined for customers in the field of small series production, job shops, as well as research and development.
