Superabrasive grinding 101 - Aerospace Manufacturing

Cubic boron nitride (CBN) is a superabrasive traditionally used to grind steels and nickel alloys. Though not as hard as diamond (4,500kg/mm 2 vs. 9,000 kg/mm 2), CBN is not chemically reactive with ferrite-based and nickel alloys, allowing it to outperform diamond-based grinding wheels in life and material removal rates on these materials 1.A 1987 study by Hitchiner and Wilks showed that when ...

Aerospace Grinding Efficiencies with cBN Superabrasives

2019-9-17  Grinding Ni-based superalloys is often done with either conventional aluminum oxide abrasive or with cBN superabrasive wheels. There are many benefits to using cBN: fewer wheel changes and machine down time, low and controlled wear rates, and excellent thermal stability. As with any grinding wheel, the cBN superabrasive wheels wear with use.
