Abstract

This paper analyses the fracture behavior of the brazed BCBN grain by comparison with brazed PCBN grain through grinding test of Nickel-based superalloy. The self-sharpening effect is created by timing micro-fracture behavior for BCBN abrasive grains, but by macro-fracture behavior for PCBN abrasive grains. During grinding with brazed BCBN abrasive grains, the material is removed together with the consumption of the CBN particle. While for PCBN ones, the fracture pattern consists of the intercrystalline fracture and the intergranular bond fracture. The service life of brazed BCBN grinding tool is around 1.67 times longer than that of PCBN one, furthermore the material removal of PCBN grinding tool is just about 73% of that of BCBN grinding tool in this investigation.
