A diamond sharpening stone is a specialized tool used for grinding and maintaining grinding wheels and abrasive equipment. Typically block-shaped, these stones vary in hardness and grain size to suit different abrasives.
Primarily used with grinders, diamond sharpening stones play a crucial role in restoring performance and preventing heat buildup. As grinders wear down and accumulate debris, their efficiency decreases, leading to increased friction and heat. Regular maintenance with a diamond sharpening stone is essential to keep these machines operational.
Diamond sharpening stones, made from hard materials like green carbonite or white arundum, are used to refurbish and maintain tough grinding surfaces. Available in various grain sizes, the selection of a stone depends on the specific grinder being serviced. Some stones may require a lubricant during use and have a limited lifespan.
To use, the stone is pressed against the grinder's blade to remove clogs and accumulated debris. This process, essential for high-speed grinders, prevents excessive heat buildup. Users should always wear protective glasses during maintenance to safeguard against flying particles.
