The aircraft industry uses the longer more CFK and other with carbon fibres reinforced materials. HEULE, having been active at the forefront of CFK machining for quite some time now, carried out trials for this customer and developed a solution.
The picture shows on the left the bore entry and on the right the bore exit after the deburring.
The difficulty in deburring bores in carbon-reinforced materials is to cut the fibres neatly and not fray them. Furthermore, these materials are very abrasive which leads to heavy wear on the cutting edge of the blade.
