The modular cladding system COAXn represents a flexible processing tool
for laser cladding applications and guarantees a stable and controllable
manufacturing process as well as the highest precision in material deposition.
It consists of different powder nozzle bodies, tips, adapters, media supplies,
and process monitoring devices, which are compatible among each other.
Thus, for various lasers, optics, workpiece geometries, and cladding materials
required by the user, an optimum unit can be composed easily.
Technical data:
- metal, composite, and ceramic powders up to 50 g/min
- minimum focal length of laser optic 70 mm
- nozzle inclinations do not influence the powder supply
- working distance (tip/workpiece) 16-25 mm
- minimum powder focus is about 1 mm
- powder efficiency can amount to 90 %
- laser power up to 6 kW (CO2, Nd:YAG, diode laser)
The current constructive design of the coaxial heads consists of three
modules: powder supply and distribution, nozzle tip unit and adapter /
adjustment unit. These modules are available in a large number of different
shapes, sizes, and materials. Thus, a flexible construction kit permits
the quick composition of a cladding head which is precisely adapted to
the requirements of the particular application.
