Drilling of Composites Using Tools of Polycrystalline Superhard Materials

详细

The advantages of using tools of polycrystalline superhard materials for drilling workpieces of fiber reinforced composites are shown. The results of a comparative quality assessment of holes produced by high-speed steel drill bits and polycrystalline diamond inserted drill bits are discussed. The polycrystalline diamond inserted drill bits have been found to provide high-quality drilling of fiber reinforced composite materials.
