Examples for tools and processes optimised to the specific challenges posed by composite materials will be presented. At Stand F73 in Hall 6 of the Parc des expositions de Paris-Nord Villepinte, Hufschmied will be showing its ultrasound cutting blades for the more efficient processing of honeycomb materials. The presentation will also focus on the Hexacut Eco tool range – designed for the milling of composite materials.
Due to a perfect coordination of a cutter geometry with a patented diamond – coating, tools from the Hexacut Eco milling tool range can perform both roughing and smoothing at high speeds. Especially in more demanding material combinations with copper-mesh, such as the CRP-M21E material used in the aerospace industry, most post-processing can be avoided with these tools. This saves time and costs. The new tool by Hufschmied is able to minimise the typical delamination, splintering, fibre protrusions and thermal damage inherent in CRP/GRP materials. A high stock removal rate and a long service life will pay off: Up to 40% of processing costs can be saved, as demonstrated in real-life customer projects.
Ultrasound cutting is an excellent method to separate, for example, delicate honeycomb materials as used in aeroplane construction. For the refinement of this process, Hufschmied has developed a new type of monobloc solid carbide (SC) blades. These blades are able to glide through the material with an up to 10-times increased oscillation amplitude and an up to 100% increased cutting performance as compared to current blades. These optimised blades are available directly via the suppliers of ultrasound systems, in lengths ranging from 7mm to 125mm.
