To meet growing challenges and increasing pressure to reduce costs, Norton Abrasives R&D engineers have developed the new Norton B74 bond, which offers longer life and higher material removal rates than existing solutions for hot and cold mill roll grinding. The new open-structure bond combined with superior grain blends increases process productivity while reducing grinding costs.
Norton B74 grinding wheels feature next-generation chemistry that significantly improves grain retention. This enables wheels to be constructed with an innovative structural composition for a given hardness, which translates directly into abrasive with the long-life grain retention of a hard grade and the ease-of-use performance of a soft grade.
The new bond technology offers reduced cycle times (up to 50%), longer wheel life, and the versatility to efficiently grind various materials. In addition, the bond retains its strength after exposure to coolant, resulting in less wheel compensation during grinding.
Stefano Natalicchio, Product Manager, Saint-Gobain Abrasives EMEA, claims: "Using fewer grinding wheels that are more productive on a wider variety of products is critical for improving production efficiency. The B74 technology enables roll grinders to reduce cycle times and overall process costs, thus increasing the overall profits."
Wheels are made to order and available with ceramic, aluminium oxide, silicon carbide grain, and grain blends.
