Norton Abrasives’ Vitrium3 bonded abrasives feature patent-pending bond technology developed by Saint-Gobain Abrasives and are said to offer several benefits over standard vitrified bonds.
According to the company, the abrasives feature a stronger bond construction that enables superior form and corner holding for improved part quality and higher tolerances, reduced dressing time and wear, as well as the ability to meet the higher wheel speeds. Norton Vitrium3 abrasives also are said to offer improved holding power with a lower bond-to-abrasive ratio. This allows increased exposure of the abrasive grains for an improved cut rate and less burn, while reducing power consumption and grinding forces on the part. In addition, increased porosity improves coolant flow and chip clearance to eliminate burn or other part damage, especially on tough-to-grind materials, such as high-nickel alloys, tool steels and chrome.
