HPTec Composite Tool Action with CCDia®AeroSpeed®: Long tool life and best surface quality

Because of their low weight and high load-bearing capacity, fiber composite materials (FRP) are being used in more and more applications. HPTec GmbH from Ravensburg is one of the world's leading specialists when it comes to the anything but simple machining of such high-performance materials. With a view to highest process reliability and component quality, the tool experts have developed the new micro cutters of the "HPTec Composite Tool Action". An important component is the diamond coating based on CCDia®AeroSpeed®.

Composites such as CFRP or GFRP consist of several layers. The specific combination of fibers, such as carbon or glass, with different resins or bonding agents, such as Kevlar, aramids or polyester, enables the design of complex components with high strength and low weight. This inhomogeneous material structure with hard and highly abrasive fibers as well as a thermally sensitive matrix poses special challenges for machinists. Reliable process solutions are required that also meet the increasing demands on productivity. "Delamination and fiber protrusions weaken the structure of FRP components. Therefore, they must be avoided at all costs during machining. A…
