Similar to cutting tool technology leapfrogging machine tool technology and vice versa, grinding wheels can trail the capabilities of grinding machines before gaining ground. To keep pace with grinder technology, Norton/Saint-Gobain has developed the Norton-brand Vitrium3 grinding wheel.

The core of the technology is the wheel’s glass, or vitrified, bond, which is the company’s strongest, according to Jim Gaffney, senior product manager for Norton/Saint-Gobain. “We’re trying to stay in step with or be ahead of the machine builders,” he said, noting the wheel is suitable for grinders with spindle speeds up to 80 m/sec.
