        Honeycomb Structure CBN / CERAMIC

GRADESA Honeycomb Structure CBN / CERAMIC                                                                                                 Core

        Honeycomb structure is the high structural controlled composite
        material consisting of a hard and superior wear-resistance core
        (gray portion) and a tough shell (white portion).

        FEATURES                                                                                                                                                          Shell

        • Cell Fibers combine a hard, wear-resistant core and a tough
          shell into one insert.

        • The tough shell stops cracks that form in the core.

        • CBN is good for interrupted machining of exceptionally hard
          material and ceramic is good for heat-resistant alloys
