  • Monocrystalline Diamond - an overview |

    The fluctuating chip load acting on the cutting edge leads to completely different wear characteristics of the WC drills when used for drilling CFRP composites, as compared to metals. Rawat and Attia’s analysis 34 showed that fracture (chipping) and abrasion were the main mechanisms observed in HSD of deep holes in CFRP at 12 000 and 15 000 rpm and feed rate of 0.1 mm/rev.

  • Diamond-cBN alloy: A universal cutting material

    2015-9-8 · Diamond is not suitable for high-speed cutting of ferrous materials due to its poor chemical inertness, while cBN is only about half as hard as diamond. Because of their affinity in structural lattices and covalent bonding character, diamond and cBN could form alloys that can potentially fill the performance gap. However, the idea has never been demonstrated because samples obtained in the …
