采用陶瓷CBN砂轮分别在常规砂轮转速20 m/s和超高砂轮转速120 m/s下对（TiCp+ TiBw）/ Ti-6Al-4V复合材料进行了对比磨削试验。研磨行为，即，分析了磨削力和力比、磨削温度、比磨削能和磨削表面形貌。结果表明，超高砂轮转速下的法向和切向磨削力均小于常规砂轮转速下的磨削力。然而，力比，比磨削能，磨削温度显示出矛盾的趋势相比，磨削力之间的常规速度和超高速磨削。（TiCp+ TiBw）/ Ti-6Al-4V复合材料磨削表面的主要缺陷为空洞、微裂纹、断裂或压碎、拔出和涂抹。
Comparative grinding experiments of (TiCp+ TiBw) / 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 (TiCp+ TiBw) / Ti–6Al–4V composites are voids, micro-cracks, fracture or crushed, pulled-out, and smearing.
