A self sharpening grinding tool is made in such a way that its cutting efficiency does not decrease over time and does not need manual sharpening at regular intervals. This is achieved by the structure of the abrasive grains and the bonding system. Bonded abrasive disks have the ability to wear in a predetermined manner, granting them the ability to fracture or break. When they become dull, sharp edges that are ready to provide fresh cutting surfaces will lie concealed under the grains’ dull outer layer ready to rise and rotate. The bonding agent must release worn out grains of dull abrasives at the right time to every provide sharp abrasives and in the correct quantity. In metal recycling or general purpose metalworking, self sharpening grinding tools employed in these sectors can sustain prolonged periods of uninterrupted use without needing tool maintenance. This is achieved while there is little reduction of operational efficiency. Tool standby time as a result is decreased.
