Abstract

An investigation was conducted to assess the grinding characteristics of aluminium alloy 4032 (AA4032) when ground with a brazed diamond wheel, especially at high-grinding speed. The grinding forces, the ground surface of the workpiece and the wear of the brazed wheel were examined. The results indicated that grinding AA4032 using the brazed diamond wheel is feasible. The ground surface was formed by ductile material removal, and the smooth areas, pile-up areas, ploughing grooves, adhesion areas and small holes of the ground surface were characterised. By increasing the grinding speed, the grinding forces and surface roughness were significantly reduced, but the force ratio was increased, possibly due to the reduction of friction between the diamond grains and the workpiece. Flattening wear was found to be the main wear mode of brazed diamonds on the wheel. Chip adhesion tended to occur in areas with insufficient intergrain distance and was also observed on the top surface of grains, especially flattened grains. It is expected that this work will contribute to broadening the range of applications of brazed diamond wheels.
