Study on grinding of SiCp/Al composites by micro-textured monolayer brazed diamond wheel

It is difficult to machine with high machining efficiency and surface integrity for SiCp/Al composite, especially for those with a high volume fraction of SiC. Here, we present monolayer brazed diamond grinding wheels that contain different micro-textures ablated by pulse laser. The dry grinding cha...

Description
Summary:It is difficult to machine with high machining efficiency and surface integrity for SiCp/Al composite, especially for those with a high volume fraction of SiC. Here, we present monolayer brazed diamond grinding wheels that contain different micro-textures ablated by pulse laser. The dry grinding characteristics of SiCp/Al composites with 70 vol.% SiC using the wheels with different micro-textures were investigated. The influence of micro-textures on the grinding force, grinding temperature, and surface integrity was examined. The results indicated that micro-textures on diamond grits can induce cleavages and form more micro-cutting edges in grinding of SiCp/Al. The wheel contains both micro-grooves and micro-hole and owns the lowest grinding force, grinding temperature, and surface integrity. The micro-textured wheel produces smaller grinding chips and less fracture, crushing, and pull-out of SiC particle on the ground surface of SiCp/Al composites than other wheels.
