EPN-F Solid Endmills for Machining CFRP and Honeycomb Parts

New solid endmills have a special edge configuration for machining CFRP composite parts and honeycomb.
The increased popularity of composites in aerospace applications creates new challenges for metal cutting shops. One of these substances, Carbon Fiber Reinforced Plastic (CFRP), can be especially difficult to machine.

These materials are extremely abrasive and difficult to machine, as a result of the different physical properties of the materials used in the layers that make these composites hard, tough and strong. Due to the harsh cutting environment, tool life can be very short when machining CFRP composites.
The impact of the cutting edge fractures the hard carbon fibers, instead of shearing material away. This process causes the cutting edge considerable abrasion that can lead to rapid wear.
In order to successfully machine CFRP, ISCAR offers hard, sharp solid-carbide tools made from grade IC02 which can be supplied on request with long-lasting diamond coating (IC2018).
