Abstract:

The influences of abrasive belt granularity and different grinding parameters on grinding efficiency, workpiece surface quality and different effects of abrasive wear throughout the process of grinding Cu-nickel-aluminum bronze were  analyzed herein. The processing tests were carried out by alumina oxide abrasive belts for grinding Cu-nickel-aluminum bronze in different abrasive belt speeds and grinding forces respectively, the amount of material removal rate, workpiece surface roughness and belt wear were measured. The results show that increasing abrasive belt speed and grinding force can increase the material removal rate and the wear ratio to some extents. With the grinding force increasing, the workpiece surface roughness increases. With the abrasive belt granularity increasing, the workpiece surface roughness decreases. When the abrasive belt speed is 25m/s, the grinding force is 43N and the abrasive belt granularity is 240, Cu-nickel-aluminum bronze grinding effects reach the best.
