polycrystalline cubic boron nitride (PCBN) composites are produced by sintering

micron CBN (cubic boron nitride) powders with various ceramics, so as to produce extremely hard and thermally stable tooling materials. Most PCBN materials are integrally bonded to a cemented carbide substrate. CBN is the second hardest

material known after synthetic diamond, but has high thermal and chemical resistance properties. PCBN composites provide extreme resistance to deformation and wear at high temperatures – typically an order of magnitude better than the nearest ceramic materials.

boron nitride powder is a kind of high hardness metal material rank only second to diamond and cubic boron nitride. It is widely used in the wear resistant materials, the impact of hard material, as well as nuclear shielding and nuclear material control in nuclear industry because of its high hardness, high wear resistance and a larger neutron absorption cross section. abrasive material,coating painting, control of nuclear fission and nozzle.

CBN (cubic boron nitride) super abrasive This paper studies the performance of these tools in superfinish hard machining. Specimens were machined by a solid PCBN tool and CBN particle coated tools with two different CBN particle size distributions: less than 0.5 and 2 μm. The specimen machined by a tool with small CBN particle coating showed more compressive residual stresses and less thermal damage below the machined surface than other specimens. Furthermore, the specimen machined by a tool with small CBN particle showed less residual stress scatter than other specimens. The rolling contact fatigue life was predicted by using a rolling contact fatigue life model. The rolling contact fatigue life predictions indicate that the predicted life of the specimen machined by a tool with small CBN particle coating is longer than that of other specimens. The results thus indicate that a tool with small CBN particle coating provides better performance than other tools in superfinish hard machining.
