- Abstract
Comparative grinding experiments of (TiC + TiB) / Ti-6Al-4V composites were conducted using vitrified CBN wheel at the conventional wheel speed of 20 m/s and the super-high wheel speed of 120 m/s, respectively. The grinding behavior, i.e., grinding force and force ratio, grinding temperature, specific grinding energy, and ground surface morphology were analyzed. The results obtained indicate that the normal and tangential grinding forces at the super-high wheel speed are smaller than that at the conventional wheel speed. However, the force ratio, the specific grinding energy, and the grinding temperature show a contradictory trend compared to the grinding force between the conventional speed grinding and the super-high speed grinding. The main defects of the ground surface of (TiC + TiB) / Ti-6Al-4V composites are voids, micro-cracks, fracture or crushed, pulled-out, and smearing.
