Maximizing Grinding Performance for Technical Ceramics

Challenges Grinding Reinforced Ceramics

More aerospace manufacturers are utilizing hard-reinforced ceramics like silicon carbide (SiC) and silicon nitride (Si3N4) due to their high hot-strength material capabilities. These advanced ceramics replace traditional, heavier, higher-temperature alloys in aerospace engine applications.

To meet the growing demand for reinforced ceramic parts, toolmakers need to utilize grinding wheels, which can help develop longer-lasting tools and achieve efficient production.

A toolmaker specializing in resin bond wheel production for advanced industrial ceramics faced challenges in achieving their customers' desired parts per wheel. Their wheels experienced an increased need for dressing, a common challenge when grinding hard ceramic materials and reinforced ceramics like SiC and Si3N4. For the toolmaker's customers, the increased need for dressing led to a higher risk of part edge chipping, overall surface finish degradation, and heat damage.

To solve these challenges, the ceramic wheel manufacturer sought Hyperion's help to increase the parts per wheel and reduce dressing frequency. Hyperion developed several tests evaluating the benchmark resin diamond grades and nickel-based and spike-nickel-based diamond coatings to help improve wheel wear.
