In conventional metalforming operations, the main way to reduce friction between the tooling and the workpiece is to apply a lubricant. Another supplementary method, which has been used for decades, is to introduce ultrasonic energy to the tooling, resulting in microscopic, high-frequency vibrations that reduce friction and improve surface finish.
Norton NorZon® Plus depressed center wheels now utilize a proprietary blend of patented, newest generation Norton SG ceramic alumina and Norton BlueFire™ zirconia alumina abrasives, combined with a high performance bond system for significantly improved grain micro-fracturing. The upgraded line has also been expanded with Norton NorZon Plus Fast Cut™ Depressed Center Wheels, offering the fastest material removal in the industry.
